TC24DA oil leak

[Soundguy]

You didn't happen to get/keep any pics to that lift/transaxle damage.

I've not worked on the SCUT TZ series any.. and wonder how their lift cover/system is in comparison with standard ford/NH lift design.. I.E. have they changed the way the unloading valve setup works.. etc.. etc.. position sensing of max travel.. etc..

Hello,

I had a oil (fluid) leak in my TZ24DA that was less than 2 years old and still under warranty. We had noticed the leak for sometime but thought the transmission was too full and it was overflowing. We took it back to the dealer and they thought we had a oil seal in the rear-end leaking and replaced it. Then one day I was mowing on a steep bank (uphill) and it stalled and started rolling backwards with me. I evenutally got it stopped and it would only go downhill so I go it back in a level spot and fluid was everywhere and that time they told me the whole transaxle was cracked, they thought the lift arms had come up and put too much pressure on it

This time I no longer felt confident in using the mower on our hills and banks so we decided to buy a new 2006 TZ25DA.

Hope your leak doesn't get worse or do what ours has. Do you notice alot of transmission whine?

Now the good part. Got the new 2006 TZ25DA and in less than 6 weeks with around 40 hrs. on it stalled like the TZ24 on another bank and when we got it to a level spot the fluid was everywhere. This time they thought it blew a seal and replaced the seal. As they pulled it up on the rollback to bring it back to me it started leaking again (seeping) and thank goodness they noticed it. This time they took it back in the shop and I think they replaced the seal again but it still leaked so they put a dial indicator on the shaft and it's a "smidgen" too long (factory defect).

Now this makes two of the New Holland mowers that have given us a very similar problem. I mow about 8 hrs a week flat and hilly terrain. I don't pull anything or use any attachments with this mower just use it as a lawnmower.
The hills and banks aren't steep enough to need weights or fluid in the tires and the tractor handles the hill well, no spinning or slipping. This tractor has never been out of 4-wheel drive and we always use the "L" (low) range setting. I've been wondering if anyone else has experienced this problem.

Now I'm afraid to use these mowers on the steeper banks and I don't know what I'm going to do.

Hey Soundguy, That would have been a good idea on the pics. Didn't think of that. Basically I couldn't see a crack but I was too busy looking at fluid everywhere on the transaxle and rear-end. At the time I noticed the seat move when I picked the deck up but it wasn't until they got it to their shop that they said the lift arm (the right side) had put too much pressure on the transaxle and cracked it. We just thought it was a "fluke" thing and after I expressed my concerns to the dealer he offered to do a trade-up to a 2006 TZ25DA.

On the 2nd tractor the fluid was all over the deck, rear housing & hitch.
We basically thought it was the same thing but they said it was a different seal but after they tried to fix that they decided it wasn't the seal but the shaft.

You're over my head on how the lift system works in comparison to the other models. We've had a TN55 and now a TN65 4-wheel drive and never had any problems with them. Basically we've had Ford tractors for over 25 years and JD lawnmowers. Now after all of this I might have to go back to JD for my mowers.

Ford used a specific type of pump and valve design from 39-52..a control valve-in-pump design.. then from basically late 52 and on thru the changeover to Nh and at least the 4 digit models up till 2002 they used a few variations on a lift cover design built around an unloading valve. Newer models are more sophisticated than older ones.. but it is still a common theme.

I havn't had the opportunity to look at the TZ, TC or TN manuals to see if they share the common ancestry and unloading valve of the older fords and Nh's..

I have a TZ25DA with 55 hrs. It developed a small drip at 49 hrs just below the rear seat on the ground, this I traced to the shaft/spline that supplies the power for the front wheel drive. At 54 hrs it was leaving quite a puddle in the barn floor. Apparently the seal for this shaft went out. Its at the dealer right now for this warranty repair, seal replacement.
Over all I am very impressed with this tractor, I have a 60" MMM and FEL. I traded a 13 yr old Ford GT75 on the TZ25DA.

Welcome to TractorByNet!

Do you have any pictures of your tractor?

Hey Jeff,

Been off here for a while due to a divorce......a very good thing and VERY peaceful! Yep, kept the tractor!

Did you find the source of the leak?

Hey Jeff,

Did you find the source of the leak?

I was wondering what happened to you...good to have you back.

No I didn't find the source of the leak, but I traded the tractor on a TC33DA over the summer. The leak no longer matters

Normally I would say, "I'm sorry to hear about your divorce" but it sounds like you are relieved. I'm glad you were able to keep the tractor!

Take care
