- In this video I repair a Tuff Torq hydro transmission out of a John Deere Z930M. The issue was that once the transmission got warmed up it would start loosing power. The longer it ran the weaker it would get.
In another video I show how to remove these hydros from the John Deere Z900s
• Z930M w/ 2455 hours hy...
I also have a video showing how to do an oil and filter change on these hydros.
• Changing the hydro oil...

Hopefully this video will help you if you are having this issue and decide to repair it yourself.
Thanks for watching! 🍻

Wow, this is the guy you want working on your equipment. Cares about doing a good job, thorough and meticulous. Great video!
Thanks Scott! I appericate that
I love the replaceable valve plates. Cheaper for the do-it-yourselfer, rather than replacing the whole center section. Thanks really love the content !!!
Appreciate all the help!
Thank You so much. Ive been on vacation and haven't gotten mine back together. But this was a great detailed video of the case being split. I really appreciate it!
Let me know if you have any questions and I'll do my best to help you get it fixed
I have a Z-spray fertilizer spreader that I believe uses the tuff torque transaxle. I need to replace one of the axle shafts because the hub was loose on one end and rounded out the axle shaft and the hub. So far this is the closest video I came across showing the tear down but I know the transaxle in my unit is different. Good work!
another great video you did
Great Video, Very Precise and Professional, I would need to take pictures as I go to get everything back in correct order...
Very good video
Thank sar. Good video . Gracias señor me dio un alivio su video y Dios lo bendiga siempre
Great job thanks.
I’m a hobbiest mechanic of sorts , mid 80s diesel Mercedes model w123 has my intrigue for its engineering . When you started finding plastic pieces I was guessing the problem to be a bearing casing . Theirs a fine little bearing on these cars that live an extreme existence as part of the vacuum pump , these will grenade then the fine bearings will find their way into the chain area while ping ponging down to the pan . The reason for the plastic must be to leave a chance to restoring operation without wasting the complete unit .
Fixed! The orientation of the block that is on the horizontal shaft matters!
That’s what I get for using pictures from the left side on the right side…
Thank you again!
Good deal. I was wondering if you got it back together!
Great video. I have a 2012 Ferris. Goes forward fine but in reverse one side is weak. The question is how do I determine if it is the Hydro Gear pump or the wheel motor? Which one do I take apart?
Great video! I like how you do close-ups and explain the whole thing. What is your opinion in quality between the Tuff Torq and hydro gear zt transmissions?
The thrust bearing is wiped, weird the other one was fine, right?
That's what mines was doing on the left side
Ty,are all hydros the same?
What was the source of that rebuild parts kit ???
Do you feel like hydrogear is a better trans? Which ones do you feel like have less problems and of the problems you see with both, which cost less in repairs?
Mine does this
$2 k just for that hydro 😮😮 pump ouch that is expensive for sure
You mentioned a few months ago you would make a video on a adjusting and setting up a MOD deck. Are you still planning on doing that?
I will when the opportunity comes up. Im kinda surprised one has not come in with MOD issues over the past few months
Both mine is doing the same thing on both sides...
question your saying for warranty 1300hrs. my undrstanding on a 920m 3yrs or 1200hrs ? thanks for your time.
These models have unlimited hours warranty for the first 2 yrs OR 3yr 1200hr -1500 hr warranty (depending on the model ). The mower in this video was only 1 yr old.
Awesome!!!! I am having the same issue with my toro timecutter 3225. But when it cools down it works again. Any recommendations please and thank you.
Open it up and see what is broken.
@@Mechanical_Mind the funny thing is it cools off and works again??? Only has 145 hours on it….
@@rigomartinez5836 that is the exact same issue that the transmission in this video had. Once it cooled off it would work again and not make any noise. When its cools off the oil is thicker
What model Tuff Torq is it that costs $2000? Even if it is a K60 or K56 it should not be near that much. Looks like the piston face and valve plate scoring was the main cause of drive failure. Thanks for the video.

where did you get the parts from and which number do you use to look up the parts
Hi James, it's super easy. In this video I show how to look up every part on your John Deere. ruclips.net/video/9JgYcXJhQvM/видео.html
Also I mistakenly refer to deere.com as an app in the video. It's just a website.
Where did you source the new ball bearing?
Deere.com
Hello!
I finally got both transmissions back together and installed.
The right one is reverse. Pushing on handle causes it to go in reverse, pulling on it goes forward.
Seems like reverse is much faster like forward would be.
Any ideas how I could have possibly screwed this up!?
According to schematic hydraulic lines at front are on correct. Has to be something directional inside? Z930a
Oh no!! I guess you might have the valve plates in the wrong postion.
Are those gold looking things that you mention are separate part numbers in the video? I wonder if I have to change orientation or swap them from shaft they are currently on. Anyway to tell for sure they on right? 😬
Thank you!
@@squeaky61 yes its the gold plate looking things. Id honestly have to reference my video to remember which one goes to which shaft. I think you need to change which pump they are on
Ok. I’ll try it. Thank you. Funny cuz on the left one I was sure I mixed them up. On the right one, I was sure I kept them correct as I saw in your video they are different part numbers. 🤷♂️🤦🏼♂️
22:44 debris between gear teeth ?
I think that was just another pc of plastic from that bearing retainer
@@Mechanical_MindThanks for the reply and I love your vids. Your knowledge is amazing and you are helping people with these in depth videos.
I film everything I do, otherwise I forget everything
Sorry - but plastic bearing retainers? Uh, no reasonable reason to implement those in this transmission.
wow people really let these mowers go to shit thing looks pitiful
Fully agree probably let grass build up on the transaxle cooling fins and over heated it, causing that plastic bearing cage to melt. Just a thought.
