Cub Cadet — xt-2 mower throws belt when deck at low height
I have a 2016 Cub Cadet XT-2 Enduro mower which I bought used with about 16 hrs. on it. It now has about 60 hrs. and has been a good mower for my 2 acres, but when I put the deck at a low height (1" +/-) the steep angle created by the belt on the deck w/respect to the engine drive pulley causes it to jump the engine pulley. This in turn allows the idler pulley arm to suddenly and forcefully swing CCW to the right and jump the left deck-suspension bracket. There's a square hole in this bracket to accept a 3/8" ratchet to allow rotation of the idler arm, but after it's jumped the bracket it takes at least two people to rotate the idler arm, reposition the belt and force the arm back over the bracket. BTW, a 3/8" drive ratchet is far too short to provide enough leverage to rotate the idler arm back over the bracket w/o an extension pipe (cheater) on it. A 1/2" drive hole for a longer ratchet would have been much better. There appears to be too much vertical play in the idler arm pivot bolt, allowing it to jump the bracket. Tightening this bolt may be futile as it will probably strip the threads out of the deck into which it screws. BTW I tried to pull the arm back across the bracket with a pipe clamp, but it just jumps off the arm when it starts moving upward to cross the bracket.
One other problem: the same as with the other Cub cadet mowers in this forum, one front tire has to be pumped up each time I want to mow. No punctures, just a bad wheel bead or tire design/manufacture.
