Dixon Kodiak Zero Turn Lawn Mower
Synonymous with the zero-turn-radius concept, Dixon has been one of the best and most trusted lawnmower brands on the market for many years. The Kodiak is one of Dixon's higher end mowers, falling in their commercial grade models.
The price is quite high, running near $8000, but there are more than enough reasons for many consumers to still consider it. The Kodiak has a very low center of gravity meaning that hills of very steep grades are no problem at all, driven either parallel or perpendicular to the slope.
It is also a very solid piece of equipment that will last for years with proper maintenance. It also has more than enough power for any application I can think of (I have been using it recently to push the Wisconsin snow off my driveway). It is made of only the best materials around.
The only major issue that I have with it is that the oil drainage cap is put in a terribly inefficient place, meaning that even when I brought it in for service the mechanics all complained about it. That said, it is a fine piece of equipment that will be around for a long time.
