I mowed with a Cub Cadet GT for over a decade,, it never mowed great,,
I asked the dealer,, he never gave me a straight answer,,
I would see a JD similar GT throwing out a cloud of clippings,, my Cub Cadet,, just clumps,,
Well FINALLY the CC dealer gave up his Cub Cadet dealership,,
one day, I stopped by,, looking for a part,, and I happened to ask about Cub Cadet cut quality,,
The guy THEN admitted,, all the Cub Cadets from that era had slow tip speed,,,
I found a deck pulley for the CC that was the same diameter, but, for a "B" belt, rather than an "A",,
since the "A" belt sat deeper in the pulley,, the mower deck ran faster,, IT WORKED!!
The Cub Cadet now had the cut quality I had seen on other GT's for years,,
WOOT!!
