Depends on which transaxle. They are available on
quite often for reasonable prices.
One of the guys I have bought a lot of Cub Cadet stuff for is Joe's Outdoor Power
. His prices are fair and so far I am really happy with the quality of his parts. Not sure if he has any 1330 transaxles - you would need the part # to be sure as there are others models that will fit as well. Since it would be an MTD Cub Cadet - I think they shared common transaxles with many other makes - so as long as you have the part# and it should be on the transaxle, then it should be rather simple to find one. Well worth picking up the 1330 and just shopping around for the best deal I guess.
This one popped up Cub Cadet 1620 Tractor Transaxle
and the price is pretty reasonable.
Watch Joe's listings - you should be able to get a transaxle for about $100.00. Now considering the rest of the LT is in good shape it would be a keeper in my books. Gear drive transaxles are not that difficult to repair - I have already done my Craftsman's Peerless 6 speed. Wasn't hard and that was long before I found farmallcub.com
Ok.. just did another google search and poof - Partstree.com - Cub Cadet 1330 S/N 207,401 - 239,300
confirms that this is a gear drive. Probably an easy fix... parts breakdown is right there. Hope this helps. Oh and I would be keeping the 1330 since he is willing to send it to the landfill
and I would repair it.
