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
