yardman upgrade trouble HELP!!!

hobbyfarmergrowerJuly 22, 2010

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???

If your tractor has the regular type of transmission, not a "hydro-static", yes, it probably will, if used carefully. If you intend to try breaking of hard ground, or plowing dirt, your Yardman isn't exactly suited for that work. Although, you can try it, but do not be surprised if it suddenly decides to fail, even with the geared transmission.
As for the muffler, i'd say buy the type for the engine!
That way you won't have to worry about back pressure, etc. Mufflers are not expensive, and are designed for correct back pressure, and exhausting of engine combustion (exhaust) pressures.

If you need to go to duals to get enough bite, you're going to tear out the rear axle. Yardman tractors like your are made by MTD and have Transmatic belt type CVT transmissions and use a Peerless 910 differental/rear axle. The Peerless is probably the weakest link in the whole drive train. The Transmatic with its belts will slip before it breaks. Replacement new is about $300+ and there is no "heavier duty" version available.

Yours is a lawn tractor and is specifically NOT recommended for ground engaging equipment. If you put duals on it, expect trouble.
