I have one property that has a very difficult slope. I have a hard time keeping my Gravely 50" from wanting to slide sideways. I think I need something lighter so I feel like I will have more control. Is there a 36" walkbehind that is best known for holding a hill? Maybe a 32" would be even better? I'd like to keep costs to a minimum as it will be basically be limited to this one job... so something used and probably gear drive would be best. Also.. It could cut like crap for all I care.. it just needs to hold the hill. Thanks in advance.
