I am attaching a sickle mower to a 1998 Craftsman GT. The engine is a vertical shaft with electric clutch. The drive pulley and clutch on the engine is three inches higher than the mower pulley and only six inches aft of the engine pulley. I had to build a pulley bracket to put idler pulleys on it. I mounted it on the back side of the dozer/snow blade attachment bracket. Still need to work out a spring tensioning mechanism, but I had it running yesterday.
