Hey, I'm Djay from Virginia, Peninsula area. The idea of flying through the forest on a lawnmower fascinates me, so that's my ultimate goal. My friend was about to junk a 14hp Murray and a 20hp Craftsman Lt3000 but I convinced him to make it my project instead and here we are. As my first post to the forum, I have a pretty brazen question. We we pulled off the transaxle preparing to pulley swap the Lt3000 it but it occurred to me it may be Hydrostatic. I've read on the forum these can't be swapped, but there are not many markings to identify it by, so I was hoping you guys could use your grand-master wizard mower powers to help me out. So the question is: Can I swap it? Thanks in advance!

Welcome! No, that is not a Hydrostatic, it is a Peerless MST 206. I have a 205 that was pulley swapped it they work fine. That's a very big pulley on there, you could maybe half that size without having belt problems. If you go too small on the rear then the belt slips because there is not much surface area. Same with the front pulley. If you have anymore questions, I'm sure someone will be able to answer them!

Welcome to the forum! Feel free to contact me if you need any site help.
That sticker is your friend. That right there is a member of one of the holiest transaxle series out there; the MST. And they take pulley swaps very well.

Welcome! As Doug and Matt have said, that is in fact a Peerless gear drive trans. A six speed I believe, I'd put a 4" or 5" on 'er and go! Haha, happy building

Yep, as they have said, MST. Fearlessfront runs a 5 speed MST in his murray. I want one since they have factory oil lube and good case bracing over the diff

No worries. When you have the tranny out of the tractor it would be worthwhile opening it up and cleaning it out and putting new 80w90 oil in it. It looks like the inside hasn't been checked in a long time.

You might want to consider adding bearings too. The MSTs used two different styles, a fatter and a skinnier one. Im not sure of the fatter one, but the skinnier one is 6203-3/4-2RS (19.05x40x12mm). About $20/pc on eBay from the states, $13.20/pc from the UK.
