Cub cadet m50s hydro gear trans

Both mine have spin on filters and I'd say my M50 tank is at least 10 years old, maybe more.

Guess I'm kind of curious how you scored the unit. Have to be dirt in there right?

I bought it from a dealer that used it to mow their business lawn . I paid $800 5 years ago. It’s in great condition , engine doesn’t leak or burn oil . I think it’s worth trying to save . Here’s some pics of what was in my unit .

And by filter I just meant the black screen that seems to come on the newer center sections. Neither looks like it matches up to my center section . I’m guessing I’m out of luck .

Looking at the center section I am surprised that the pump and motor are not both trashed with fingernail catching grooving.

Two things will lead to scoring. Overheating due to overload or improper cooling due to broken cooling fan or debris buildup. The other is shock loading which the shock valves should help prevent, but in fast direction changes the pressure spiked can cause the pump to lift off of the mating surface on the center section and then slam down causing metal to metal contact.

The pump and motor are trashed too . Not as bad as the center section but they have slight grooves . I can find those parts , just can’t find the center section.

I think I’m leaning towards the 71563 part . Looks like it will work . What model trans did you find it in ?

That center section fits several different variations of ZT transaxles, including on of the three drives that was used on your mower.

Do you know the actual serial number so I can pull up a parts schematic just to see if it’s different than mine . I’m pretty sure I can put those parts in the case I have . Just want make sure nothing else is different . Thanks for your help !
