Cub 3648 deck swap compatibility
 

Cub 3648 48" zero turn. From what I can find they made them 1999-2000. Shaft driven deck. Came in 48, 54 or 56, and 60" decks. I've found a couple shaft driven 60" decks on FB and I'm just wondering if they would fit. Haven't found much information. Some say they are "mid mount" decks, but I'm not sure what that mean. If I have to cut the mounts off my current deck and weld them to it I'm willing to do so.

The shaft driven Deck's our More than Likely for the Cub Cadet 3000 SERIES garden tractors some Could Be for the Cub Sub compact or Compact tractors as well

Mid mount is where the deck is under the machine. A lot of Grasshopper and a few others machines have the deck mounted out in front of the machine.

Can you post some pictures of your machine? When I looked in the Cub Cadet parts lookup it shows that deck being belt driven with a vertical Kawi engine.
