Is your friend sure that Sears Craftsman is a garden tractor ?
All I have ever seen at sears were lawn tractors, with very light tinny frames.
How long a laneway does your friend, that thinks this will work, have ?
Hopefully he got a lawnmover attachment with it, so it won,t be a total bad purchase, and will be able to at least use it in the summer.
Sears made garden tractors and I have one Sears Suburban 6 that came with plow disk and cultivator. mower could be hung under the frame and blade in front. 6 speed transmission.
