Sounds like transmission problems. See if you can take a sharpie and mark the hub to the axle and see if it is stripped. Run it and see if your mark moves, if not pull the rear cover and look for problems. I have not heard of the problems your having yet on any of the forums. Good luck and let us know what you find

Thanks,

I will take a look at the hub and axle when I get home tonight.

I am wondering, should you be able to drive the tractor with the lever for the transmission pulled out to the disengaged position?

Nate, you may want to do a post on MTF. There are a lot of 3000 series owners over there too.

Hi everyone,

Final got to revisit this and took the tractor back to the cub dealer. It ended up being two bolts the plate at the front of the transmission were loose. Felt a little silly have to take it to the dealer and pay labor for that but at least it's fixed.

Thanks for all the help!

3185 oil leaks
 

My 3185 was jerking . Found the hydro adapter coupling and wavy spring washer had come loose. The shaft going into hydro wasn’t turning. I had to take fenders off? I rebuilt three hydraulic valves with all new o rings in valves and all lines. Installed new input hydro seal. Then replaced four plastic flange bushings on pedals. Moved onto steering slop and ordered new parts for lower coupling and plastic cup. I painting little stuff as I go such as levers and Parker’s and lift parts. Lubing all as I go. The Parker valve had too long of a bolt going into one valve. I had to hone it to get spool back in. What a nightmare those three valves were getting out and repairing. Going to remove battery next to paint pedestal then 2 new tires. I'll check bearings and axle bronze, then onto deck rollers, and front wheels. I'll strip all both sides, prime, and paint. I made new rubber lever pad for left fender. I punch kit and traced out old one. Used razor blade between punch holes and used a socket for lever centering holes. Turned out perfect. I saved 20 dollars. Unfortunately my original left brake light had cracks so will get a new one. This all started from a blown tran side crank seal on engine, so will keep going on it.

So what is the point of all this
replying to a 5 year old thread?
:Huh:

My hydro adapter coupling at rear of driveshaft came loose. A nut and a wavy spring washer. Had to take rear fan blade out for access. 20 ft in’s torque. I could see that rear shaft going into hydro wasn’t turning with driveshaft.

Well we are glad you got your little problem fixed, but replying to the original persons questions is like showing up for a reported fire, 5 years after it happened,nice gesture but a little late.

I see you are new, so in the future it might be more beneficial to either start a new thread if you have a problem, or respond to a current post so it is helpful to other people.

Now if you just want to chat there is "off tropic" or general talk, jokes/humor etc.etc
