John Deere JS25 Walk-Behind Mower

Our John Deere walking lawn mower is the greatest and I can't be happier with it. At first we were worried about spending that much money on a lawn mower, but after using it all last summer, we are glad we did. We had previously gone through 2 other mowers in the last 5 years and were very disappointed in those for they didn't cut the grass as well and seemed to needed to be worked on all the time, so basically the John Deere has paid for itself for the years to come.

It has some great features as well, it has a 3-in-1 blade and works great for mulching and has a attachable side chute that the grass can be shot out of.

John Deere's special MowMentum System means it adjust's it's own speeds by moving the pivoting handle to control how fast the mower moves by how the handle is set, which you can also lock into place.

This machine is extremely durable and I know it will last along time. The grass bag is huge and holds alot more then the other mowers we had, it is made out of some sort of tough fabric and not that netting material in cheaper brands, it can be removed to be cleaned with a hose and then hung to dry.

I would totally recommend this lawnmower to anyone, John Deere has been around for a long time and their specialities are in farming for large areas of work so you know that their products will be great.

I love this lawnmower and will only buy John Deere lawnmowers from now on.

Buyer beware of this product
by: Roger Carlough

Initially happy with the purchase of the mower that I purchased at Lowe's but now totally unhappy. Only have had the mower since August and was happy with the performance. In October while mulching leaves-I hit a tree root about 2-3" above the ground. The mower stopped and I checked for damages-it seemed to be OK and the mower restarted and I continued using it through the end of the fall season.

This spring, mower started without issue but now the motor has seized. I have an extended program with Lowe's so I called in. They had me take the mower to a repair center and I waited over 2 weeks to get a call back on it. Initially they told me the blade was bent and it would cost $100 to repair-they called back an hour later to tell me that the bent blade caused damage to the motor and that I would have to replace the entire motor. How is that possible-you can a bent blade cause the damage that they are reporting.Also, they told me that grass was in the self encased motor-how can that happen? I told them I wanted it replaced by the manufacturer-they told me that it would not be covered and I would have to spend $350 for a new motor!!

At any rate, called Lowe's again-they will talk to the service center and see what can be done. Not expecting any help. Also, JD contacted and they were no help at all.

I did also read that the mower model is being replaced-why? I have also read and experienced that grass clippings get stuck underneath all over and it is a pain to clean which it is. Again, i think I got screwed-buyer beware of this product

Powerful but loud
by: Phil

I bought the JS25 yesterday and mowed with it. It is a bit bulkier than my previous mower and I have a tight lawn so it is gonna take some getting used to.

Also, It is very loud, Guess i'm gonna have to get some ear plugs. It is very powerfull and didn't bog down even in the thickest spots. I give it a 7 out of 10 mainly because of the loudness.

update to "some stalling suggestions"...
by: batpot

First of all: John Deere customer service is worthless. They were adamant that it was Briggs & Stratton, not John Deere who were responsible for handling the warranty, and claimed it was B&S who denied the warranty claim.
I followed up with a visit to the dealership, looked at the disassembled engine, and spoke to the owner who said that the mower is actually made by B&S for JD…the WHOLE MOWER. Really?
He said that it was in fact B&S who had denied the warranty claim, but said that the B&S rep would be visiting, and they may be able to work something out.
A few weeks later, I get a call from the dealer, who was able to convince the B&S rep to do a sort of "courtesy" replacement engine; so it's not a warranty repair, and I still have to pay the dealer for their labor to install it, but all things considered, I'm satisfied with this compromise.
I had previously filed a BBB complaint against the dealer which may have motivated him to work for me, but may not have. You might also want to involve your state's attorney general, and if this engine is burning oil as bad as it seems to be, a class action lawsuit (against probably B&S rather than JD) may also be viable?
For those with failed engines, here are some useful links:
JD parts catalogue (just type in JS25):
http://jdpc.deere.com/jdpc/servlet/com.deere.u90490.partscatalog.view.servlets.HomePageServlet_Alt

What I BELIEVE to be the correct replacement engine:

…I matched the crankshaft part number (691450) from John Deere's alphabetical parts list to the number on B&S's website:

a piece of junk
by: Anonymous

I bought my JS35 in April and it quit working last week (Nov. 5). This year it's dry and I used it for about 30 hours. The dealer just called me and said the rod is broken, probably due to low oil, although I'm pretty sure the oil was okay when I dropped it off. The warrany doesn't cover it and they want $150 for diagnosis. It's interesting to see so many people having same problem.

JS25 is a great mower...
by: Josh

I purchased a John Deere JS25 almost two years ago. It was a little pricey, but you usually get what you pay for. Like others on this post, I had some trouble with the mowmentum drive handle shutting off the mower. This was easily fixed with a small drill bit and about 5 minutes. I drilled out the engine side bracket that the cable slips into and moved the cable forward to give more tension. (3rd or 4th use.) The only other issue is also mentioned in a previous post. The air intake is too close to the deck and the discharge/mulch plate which allows clippings to clog the filter often. (Maybe once every other cut on a 1/2 acre lot.) To remedy this, I measured the size of the current intake holes along the bottom of the housing to figure out the surface area of the openings. I then JB welded them closed I then drilled out the side of the housing with the same square centimeter of surface area open. This works well because now the intake openings are well above the discharge and you still have the protection of the filter and pre-filter. I admit that it is a little aggravating to have to do this, but the reviews of other mowers were quite worse than the JS25. Other than these two extremly minor issues, the mower has worked great. Starts on the first pull after sitting all winter. (After properly winterizing and storage.) No more clogged air filters, no stalling, easy to adjust deck height with one lever, great pulling power, and very smooth cut. I do wish that I could find one of the John Deere extreme blades to fit the mower as the OEM blade has a very low rockwell hardness and needs sharpening about every 3rd cut. I would most definitely buy this mower again and recommend to someone else.

Poor Excuse for JD
by: CT Lawn

I posted here months ago & I've figured out the problem- I bought the wrong lawnmower- I'm no lawnmower mechanic but I was able to, after hours of my time- able to figure out how to rig this mower to work right- the simple fact that I had to rig it to work right- in it's first season out of the box, tells me that this was a product put on the market without proper testing, with little care for the consumer purchasing it & with little concern over the consumer impression of an inferior product because this company can still sell much more expensive machines to others & not care how they piss on your head by selling the average middle American a lawnmower that has many flaws in design & machinery. Shame on you John Deere. Just another example of how Big Corporate will do anything for a buck.

js25 junk
by: Robert harding

I purchased the JS25 on June 9th and liked the mower. I went out to run it on October 9th and heard a loud bang and it stopped running. I took it to the dealer and they said it was low on oil and the motor was junk. How in that short of time did a new motor burn all the original oil out. I mow about once a week for an hour. Deere was no help. Never buy a Deere. What a piece of junk. It was interesting that someone else had the same experience.

some stalling suggestions, and a warning
by: Anonymous

Right out of the box this mower would stall every time I engaged the drive train w/ the handle.

By disengaging the spring that holds the kill switch open, I figure out the problem is the "presence cable" was slightly too long, so that when you pushed the handled forward to engage the drive train, it would release just enough tension allowing the kill switch to close, stalling the engine.
The good news: this problem is covered by warranty, and the local service center remedied the problem for me by replacing the cable at no cost.

I've also noticed that the air intake port where the air filter is can be easily clogged with grass, causing the engine to stall, so some of you may want to investigate that as well.

Now the reason for the 1 star rating: the engine failed in less than 6 months, and they refuse to fix it, claiming it was run w/out oil. Due to a very dry summer, I have run the mower fewer than 6 times since purchasing it in April. About mid way through my last mowing session, there was a loud KACHUNK, and the engine immediately stalled. Trying to pull start the engine caused the blades to spin, but the engine was toast.
The service center claimed that the bolt holding the engine rod in place was shredded, suggesting lack of lubrication, but could not explain to me how 1/2 quart of oil was lost in less than 6 months with only ~5 hours of running time. Then they informed me it would cost $140 for their "diagnostic", which was not mentioned anywhere on the paper that I signed when I dropped the mower off with them for what I was certain was another warranty repair.
I can buy a whole new engine for $150!

This may go to small claims court, but first I'm going to contact John Deere directly, and see what they are willing to do. Wish me luck.

How to prevent engine stall while using MowMentum
by: Anonymous

Just like Bob found out. You can prevent the engine stall by pulling the cuttoff cable slack toward the motor. Then use cable ties to secure it.

My mower stalls too
by: Anonymous

I've owned the JS25 for about 9 months. The first few times I used it was great but then it began to cut off frequently when in the drive gear. It does it about 50 percent of the time and its very frustrating. Until I read the comments on this site, I thought it was just a minor problem but apparently this mower is a piece of crap. This was the most expensive mower I ever bought and I thought it would be the best but I could have paid a couple of hundred dollars less and got a better product. John Deere needs to take care of this problem because I know they have had many complaints. I will be the next complaint.

by: Anonymous

I have bought garage sale mowers that work better. The biggest problem is the automatic cuttoff system. It is so sensitive, if you release the cuttoff so much as a hair, the mower cuts off. this mostly happens with the momentum drive engaged. I think the temp. of the mower has somthing to do with it. upon first start it works fine but after about ten minutes the issue starts. if you pull the cuttoff cable slack toward the motor, the problem is somewhat less. toward

complete junk
by: Anonymous

purchased this mower after my deere mower for 12 years had some slight issues. so instead of putting the repair money into a 12 year old mower decided to purchase this mower (what a big mistake) within 4 cut, mower jammed, clogged and walk behind mechanism now does not work. Corporate Deere was no help claiming I did not know how to read the manual or use the mower. Corporate should add pages to the manual explaining how to use the mower while pulling it, as it works better backwards than fowards, guess this is corporate deere way of keeping us fit and trim. ABSOLUTE COMPLETE JUNK, going out and purchasing a honda mower.

I can;t seem to figure out why the Momentum lost momentum in it's first summer of use. I did everything that they say to do. Now I just push the mower to get it to move. Wish I didn't buy this mower. Seems like I'm not alone. What a crock that JD is this top quality product- this mower is junk.

Major problems!
by: Anonymous

I thought I loved this mower! Was easy to use and a breeze to push. I treated it well, hosing it down after the 12 or so times I used it in less than the one year I owned it. Then, one afternoon while mowing, one of the front wheels began to wobble, and upon further inspection it appeared that an axle had snapped. Fast forward through much frustration w/ dealer I went to...they claim the crank shaft is broken and it would cost twice what the mower is worth to fix it. I paid $389. last July, and they claim it would cost $785. to fix!
Hopefully I will get a new one, as it is under warantee. We'll see.

The John Deere JS25 is a great machine
by: Briggs_racing

Hmmm, my Craftsman self propelled walk behind just died after 9 years, time to get a new one. First I checked out the John Deere JS25 AKA Snapper at the John Deere Dealer, great quality, built to John Deere standards, then checked out the equivalent Snapper at Sears, MUCH poorer quality. Also checked out the TORO SR4-20092 at a REAL TORO dealer, quality lookin' good, checked out the equivalent TORO model at Home Depot built to their standards, once again MUCH poorer quality. Our local John Deere dealer handled TORO during the past few years but dropped them because of getting poor service from the TORO rep and parts orders not being filled promptly, that cooled me on TORO. I ended going with the John Deere MowMentum JS25, I am extremely pleased, the MowMentum drive works great. Being a lawn mower racer and having torn apart old John Deere riders, their quality is amazing, this definitely helped push me toward a genuine John Deere as well. Yes, I am a happy camper.

A stalling disappointment
by: Phil C.

After a lot of research and discussions with lawn mower shops, my wife and I purchased this JS25 mower. It has a lot of nice features, such as the single lever hight adjustment, electric start, MowMentum, mulch / bag / side discharge. And it is a JOHN DEERE. The first mow was very successful, however, it went downhill from there. The next 4 mows were a disasters. The lawn mower started to stall as soon as you would engage the MowMentum. Tonight would have been the 6th mow, but when I barely move the handle to engage the MowMentum, it stalls. Huge disappointment. Instead of a reliable tool, it appears that we just bought a lemon. I am about to call John Deere and I am expecting to have a bad experience (isn't that what happens when a company sells a bad product). We already regret this purchase. I will add another post here with the outcome of my repair/warranty experience with John Deere.

JS25 is a great mower
by: Anonymous

In August of last year, I purchased a John Deere JS25 mower for my small lawn mowing company in North Idaho.Itreplaced a 2005 Husquvarna push mower. It did not take long for me torealize that this was a smart purchase. My JS25 is a way better mower than my Husquvarna was. All my customers compliment me on how much better my JD cuts. I would recomend the mower to anyone.

Very sturdy
by: William

I just recently purchased a new push mower about 6 months ago. It was finally time to get rid of the no name Frankenstein that I had. Don’t get me wrong the mower I had was old faithful and very easy to fix with the little 5-horse power engine on it. I looked into all types of mower from riding to standing self-propelled and everything in between.

Some of the leading companies out there have a lot to offer from the Ariens that have push mowers and trimmer that you also can push to the Brill manual push mower. The Craftsman and Snappers that Sears offers made the decision hard on me. To many companies to little time what seemed to be the best value in my book was something you pushed but not too hard. I mean a self-propelled model that really does the work for you but not all the work.

I couldn’t see dropping four to five thousand dollars to sit on my but to mow the lawn it just wasn’t the way I did it as a kid. I did decide to go with the John Deer brand some of the reason is the brand. John Deer has been around for a very long time and it was the brand that my grand father used back on his farm. They offer a very competitive price for about 450.00 dollars you can get a self-propelled walk behind with a bag attachment. I ended up getting the JS25 walk behind with a steel deck.

This model is very sturdy and the adjustments are great and easy with a Briggs & Stratton 190 cc engine it has enough power. You can adjust the speed that you need to be able to have a nice and easy day outside and think about all the exercise you can get.

Quick Start is a bonus
by: Anonymous

My mower is fairly new (purchased in August) so I’ve had limited usage. But I’ll talk about what I like so far. It’s a John Deere 21” (model JS25) self propelled quick start mower.

What I love about this mower is the quick start. It starts immediately. I’ve had other brand new mowers that took a bit to get started, having to adjust the choke and speed. This one just works the first time and you don’t have to worry about adjustments. My old no-name mower rarely started without giving me a workout first.

The John Deere JS25 also has what they call “Mow Mentum” speed control. Basically, you can adjust the speed of the self-propelled wheels better than any other mower I’ve used. My last mower either ran too fast or so slow it would stall on longer grass. What really bothered me was when the ground was still wet, the mower wheels would dig into the soil then the cutting blade would hack up the grass. With the JS25, you can easily adjust the speed as you mow. So when I walk towards areas of the lawn that I need to be careful with, I just simply slow it down. And it doesn't stall easily. The 21” blade reduces the time it takes to mow my lawn and it looks a lot neater afterwards.

Other features are a mulching bag (not much different than any other mower), large wheels (it makes it a little easier to control) and a height adjuster that’s easy to use (large handle).

The downside? It’s expensive compared to other brands. I paid $399 which is more than I’ve ever paid for a mower before. John Deere’s signature green/yellow paint scheme looks nice when it’s clean but not as nice after use. Maybe I just have to get used to it since my last mower was dark red with black wheels and never looked too dirty after use. Since you have to hose it down anyway, I would recommend cleaning underneath the deck. The mower tends to collect clippings that don’t fall out and it’ll clog up after a couple of uses.

Don't Buy This Mower
by: Anonymous

The design features of the John Deere JS25 mower make it cost probitive to operate. I recently purchased one and after mowing my lawn twice the paper air filter became totally clogged with grass, to the point that the mower barely had enough power to pull itself. A new filter costs around $12. It is virtually impossible to install the filter so the grass can't bypass the foam cover and go directly into the paper filter. This is a terrible design feature and makes the mower cost prohibitive to operate. My other concern is that if it ceases to start, there are no engine adjustments the owner can make. Everything is set at the factory so it has to go back to the dealer for repair, which again makes the mower cost prohibitive to operate. Stay with a mower of simple design, with a traditional foam air filter, and get years of trouble free service.
