Hey guys. I'm planning on putting duals on the 702 for my son this winter and wanted to get a jump on the project. I have been reading the past couple of days and have a few questions. Might as well ask the experts..... 1) Are there aftermarket wheels available? I have looked through several websites and cannot find any that seem to match stock. 2) Steel tube with flanges or spacer ring with bolts? I am pretty comfortable tackling any welding project, so the first is not a problem. The simplicity of the ring and bolts is very attractive though. Are there pros and cons to each? 3) What am I going to tear up? I have read a few posts on broken axles, but it does not seem too common. This little tractor is mainly a toy for my 8 yr old son. He rides it around the farm, through the woods, etc., monitored or course. There's uneven terrain, ruts, small gullies a creek, etc. He may pull a two wheel cart on occasion. During the summer, I cut 1/2 acre with it on occasion just to enjoy it. But it is not a real worker like some of yours. The duals are mainly for the cool look. Thanks for your help! Brian
