yardman upgrade trouble HELP!!!
ive recentely got a job and earned myself some spending money, i originally thought that i could get 2 rear tires for my yardman and drill holes in the rims on both, and bold them together, would a 1992 12 hp yardman rear end handle that type of traction?? also i found a muffler for a farmall cub same size inlet but im wondering if it would cause too much back pressure on the engine?? if so is that bad???
