I bought a new MZ61 Zero Turn this spring. Having issues with really bouncing a lot over rough terrane. I have a Scag Wildcat before and it new bounced this bad. I figure it was a lot heavier machine. I can't use this thing on my back lot because I like keeping my teeth in my mouth. After reading some other posts, people suggest lowering the tire pressure. I don't think this will solve all my problem. Can weight be added to front end, since all of the weight is in back? Small cinder blocks? I hate taking a hit on a 6K mower that I can't use on all my property. If I'd known this, I would have bought a traditional lawn tractor. I test drove it at dealer, but on smooth grass.
