Mad the mistake of by a Kohler riding mower about 5 years ago. 24HP motor on it has lousy torque, won't back up an incline, burns oil when going down or across an incline and now the the axle on one of the rear wheels just sheared off today. I don't have a lawn in the traditional sense as my house sits on a hill surrounded by pasture so I need a mower that can cut on an incline without losing power. fortunately I have a DR brush cutter with finish mower attachment that will get me by until I pull the trigger on a new one. Any ideas on tough mower that will last?
