I have a Deere D140 that the hydrostatic drive just started

Customer Question

I have a John Deere D140 that the hydrostatic drive just started not pulling going uphill, it runs fine on level ground. I changed the drive belt, but it did not help. Should I try to change the transaxle oil before giving up and purchasing a new transaxle?

Have you confirmed, whether or not your new drive belt is tight enough, and is not slipping?

Expert:  Donald replied 1 year ago.

Before purchasing a new transaxle, there are some things you should check first.

Expert:  Donald replied 1 year ago.
  • Double check, to make sure your drive belt is tight enough.
  • Check the control arm on your transaxle, to make sure it is moving fully into forward and reverse positions.

Check the bypass lever on your transaxle, to make sure it is fully releasing, when you push your bypass/roll rod in. Sometimes if you have a build up of dirt and debris on your transaxle, it can restrict movement of your forward/reverse control arm, and your bypass lever.

Make sure your brakes are not partially sticking. If everything looks okay externally, then I would consider checking your oil level in your transaxle.

Expert:  Donald replied 1 year ago.

Your oil level should be within 1" from the top of your fill port. We can continue from here. Thanks!

If you have to add oil, you will need to purge your transaxle afterwards.
