I just bought one of those Lesco caster sulkys and I'm haveing trouble backing up with it. One or both of the wheels will turn half way around and then bind in the grass causing mower drive wheels to dig nice holes in the grass. I have to do a 3 point turn with some body english to keep it from happening . Even then it still happens sometimes . It definately seems worse in thicker grass (full sun St. Augustine gets REAL thick). I'm using it on my new Toro 52" Hydro T-Bar. Anybody else use one and have this problem? Does the Bullrider do this? Would I be better off with a Velkex2 or a Jungle Wheels. I mow some decent sized properties (not the 4-5 acre ones some of you talk about) and some fairly tight stuff so I need to be able to back up frequently.
