I bought a AGS2140 used from a dealer last year - I'm proud owner of a cub cadet !! so the beginning of this wisconsin winter we put the snowblower on - got 50 feet and it 's like the transmission went into nurturl and won't go back into gear - the local dealer said it was used so they won't cover it of course - so now I went to E-bay and found hydro transmissions from a HDS2155 and a HDS2135 and was wondering if either of these would fit in my cub or which one would be the best one to put in my cub - sure would be nice to ride my caddy of the yard again - thanks in advance if anyone could help me out !!?!?!
