This has worked great so far with my Troy Bilt ZT that had a weak left side hydro. It would whine and worsen as it got warmed up anywhere between 25-40 mins. Sanded it with 1000 and 2000 grit block, cleaned everything up, and now i swear it almost feels a little more powerful than the right side. Tracks straight and even again. Well worth the effort especially If the only other option is a new center section or complete unit. THANK YOU!!

Just purchased one today with 425hours fairly decent shape been watching you for years so I knew just where to come back to for reference!

That is the video I have been waiting for. Most others leave that part out of the video. Thank you!

After a year of delay and excuses, I followed the steps Doublewide6 gave, and it worked. the mower now pulls on hills and works as it should. Thank you.

Thanks for posting, I was able to repair my Hustler Sport left side trans and saved myself about $1300.00. One thing I did notice that the unit took about 20 minutes or so to re-prime before it would work. Had me worried there for a moment. Works good as new and does not make the whining noise when engaged.

Thank You for the lessons and advice I learned a lot from you on these units, I can’t wait to try my luck pu on one 😊

Just wanted to thank you for posting your video on hydro gear repair. I followed your recommendation and sanded the pumps and pump base housing with 400 grit stepping up to 2000grit. Your procedure was spot on…my weak left hydro gear (cub cadet ZTR LX50) works perfectly. I mow around 3 acres, hills and wooded and this zero turn mower performed flawlessly for 2.5 hours. Thanks again!

Excellent diagnosis and repair. Saved a bunch of money. Hope it lasts a good long time. Thanks for the video.

LOVE THIS VIDEO - Question: Is there a reason you couldn't just use different whet stones instead of the sand paper?

Well educated husband! "Dad, dinner is ready, Mom needs your help!" without missing a beat: "Okay, I'll be right in." Then he continues with what he was doing......

I will for sure try it several times before I give up After all your learning each time you do it 😊

Great video. New subscriber now after watching this and your Cub Cadet tractor that was smoking and spitting out fuel and oil, the one where the crankcase and oil filter was full of gas. Great stuff, thanks for these videos!

Thank you . . . . I'm learning heaps from your vids. Hydraulics is a whole new world for me

Love the video. Great teaching tool

A very helpful video. Thanks for sharing.

Well done! This is the BEST vid you've done. You got right into the heart of problem and showed us how to do it. As I recall, The price of the center section is about $125 plus the cost of the pump and the wheel motor. Parts alone are vver $200. Well worth the time to resurface these components. Thank you!

I personally like the serviceable hydros with filters. I just bought a Hustler Fas trak 54 with ZT 3200 hydros. Ft691v Kawasaki 22 hp engine. Man I love that thing.

Centre section in Australia is $400+ you saved me heaps

Worked for my cub cadet sltx 1054

Thank you for the video. This video really clear up how hydrostatic transmissions can fail with no super obvious defect. These pumps and motors are wearing at their merry-go-round sealing surfaces or maybe gouge is a better term causing them to not be able to maintain high hydraulic pressure needed for producing torque. They make use of highly critical tight tolerances to maintain high seal pressure and just a little gap in the thousands of an inch will bleed off the high pressure they need for producing torque. I think its a bit analogous to piston rings, but its a rotating assembly. Piston rings are expected to allow a certain amount of blow-by so this sealing environment is actually more difficult to manage. I'm surprised such a system can maintain a seal. The high pressure is forcing it apart and it might be likely to want to oscillate up and down. That might be what the sequel noise comes from as the breed through areas quickly changes shape varying the amount of oil that breeds through. My father got a Gravely zero turn mower in 2004 and I was the person that ended up using it. From the start the mower made squealing noises and one hydro transmission side got weaker and weaker. When it got hot one side would only have about half the power of the other side. You could still use the mower by biasing how much handle was applied. I'd change the oil in the hydro drives and one side would have oil that gotten a green color in it, like grass green. The other side oil would appear dirty maybe a little green tint to it. The hydro transmissions would run a lot better for a while after changing the oil in them. I think I flushed out the oil a few times to where the oil wouldn't turn green right away. I was very frustrating and I was investigating online what might be the cause of this behavior. There was really no information available 2004 - 7, even though hydro static transmissions had been in professional lawn care for a good number of years. My guess was the problem was likely relatively simple and cheap to fix if somebody wanted to go to the bother. I finally got a diagram and basic understanding of how these hydro static transmissions work and really there didn't seem to be any clear area they could go bad in that wasn't due cataclysmic failure. Obviously if the pump or motor case were to crack or the pistons were to crack or break or springs break that would be a means of failure, but if it were due to single piston cylinder it would seem the problem would be cyclic pulse and noise and that wasn't present. I just couldn't see how the mechanism could be failing in the way it was. That mower had been taken in for warranty work a numbers times for other matters and the dealer obviously didn't want to do anything on the transmissions. I think the transmissions were suppose to be non serviceable. To change the oil I'd use a suction pump through the vent hole. I the method left a bit of oil in the transmission, but not much and the oil was changed numerous times to flush the system out. There were lots of upgrade fixes for that mower and it got all of them according to the dealer. After about 2 1/2 years my dad had gotten tired of fooling around with this Gravely and got a Toro zero turn. We sold the Gravely for $500. It also was very hard to start sometimes just barely turning over and in cold weather it wouldn't. I fixed that by replacing the small tractor battery with a regular group 24 car battery. I'd recommend always replacing a lawn tractor battery with a 'real' battery. They last much longer and start the tractor much better and can be used to jump start other vehicles. The Gravely had room for group 24 battery under the seat. There was very little clean up that had to be done to place it. With the hydro transmissions flushed out with new Amsoil synthetic 60W oil in them the mower still didn't want to go up the large hill in the backyard, but that hill was due to a it being a dam. Many years later a lawn care person mowing this lawn told me we had the most difficult to cut lawn in the area with that steep hill. The synthetic 60W oil greatly reduced power loss due to heat and it seemed to stand up to whatever the transmission had been doing to destroy the other oils I'd put into it. The person that purchased the mower seemed to just want to play around with zero turn mower and on the flat its problems were greatly reduced. For $500 in 2007 a person really couldn't have access for zero turn mower to play around with so I hope and maybe it did work out for him. I spent more time figuring out that Gravely mower than I'd ever spent on lawn equipment in the past. I'd expected to spend more time on it being I'd only had experience with walk behind mowers before and riding mowers were notorious high maintenance machines, but this was likely restoring an old abused sports car and it was suppose to be new. I wonder about that. The Toro seemed to have many of the same transmission components and such as the large single cylinder Briggs engine, but with a small three bladed deck instead of the two bladed deck of the Gravely. Everything on the Toro worked better from the start even though all the components were driving a considerably bigger mower than the Gravely. The Briggs large single cylinder on the Gravely seemed to be at the bottom of Briggs engine trim level; whereas, Briggs large single cylinder on the Toro seemed to be above the highest trim levels available from Briggs with a special Toro muffler. Even though the Toro had almost the same Briggs engine as the Gravely I noticed in cutting the same lawn it seems to use only about 2/3 the gasoline the Gravely did.

Very informative. Thank you for this video!

Thank you for this video! Do the part listed fit most (if not all) of the ZT 2200 Hydro-Gears? My son (12) purchased an 2015 Cub Cadet and the left side is super weak. He purchased another unit two years ago and we just replaced the Gear but this model is $800.

Nice fix.

Perfect video love the info

What a great helpful video. Thank u!

My brother didn't want to put in money into his 10-year old JD X304 with a transaxel issue and gave it to me. It's got the K46 transaxel. I stripped it down last week and I've got the exact same center case problem. I was wondering if I could sand it...BINGO! You save me $460 + shipping. Consider me SUBSCRIBED. Great stuff.

I followed your video and rebuilt both of my transmissions great content. I bled them per your video. But one works as it should and the other doesn’t work at all. Any suggestions would be appreciated?

My left one was the weak one, but I did this repair to both of my transmissions. Purged them both and the left one worked great with the wheel off the ground but won't move when on the ground. The right one works great. I pulled the left back apart and resanded because I saw some faint scratches with a Magnifying Glass. Purged it worked great with tire off of the ground, but won't move with it on the ground. It tries to move, so looks like I will have to buy a new Center Section for that side. Hate that it didn't work for that side.

I'm going to give this a shot with my 2011 toro 5060 timecutter zero turn. Thanks for producing this video.

really great vid- thankyou

need a 50" deck great video

sanded 2 times still want go this has been the hardest repair im doing this for a friend

Hi, I have a Ferris 400s and it has ZT3100 hydro deives, not sure if this is a problem but if I jack the drive wheels up and engage the bypass levers the left wheel still turns when I move the main levers forward and back. The right wheel will not move, I can stop the left wheel from turning if I hold onto it by hand with a tight grip. Any thoughts if there could be an issue with it?

Good fix, Will come in handy!!!

Are the drives the same as in the Grasshopper 725? I have a Cub Cadet Z-force L and the 725 Grasshopper, and both have the left drives that are weak when they are warm. The Cub probably has the same drive as this. The Grasshopper has filters on each drive on the top. It has the 3 cyl liquid cooled gas engine. Thanks for posting this. Smiles!

Excellent video thank you! I wish you lived close to me I’d have you help me with mine. What source do you recommend for the seal kits. I have a 52” Hustler with ZTC integrated transmissions. Thank you 🙏

Great video mate should help a lot of people out.. and save them some money.. hope you and the family are all well..

Great fix Bob.

After resurfacing whats the expected life span before the issue Reoccurs? And whats an estimate on how many times this is possible before needing to buy new parts?

Do you do rebuilds for others if they send you the pump and how much do you charge

I have a 48 cub cadet zero last one with no oil filter,left side is fine,I'm going to try your method cause makes sense

Hey hey so my axle came out of my Cub cadet do I need to take the whole transmission out take it apart and is there a pen that I need to put on the end of the axle if you could help that be great

Good job, great video

I was wondering if a guy could do this...they sure know how to charge for the pumps and center section. Thanks for all your videos:)

Hola soy de argentina me encanto el video disculpe el idioma ,no hablo inglés, es muy difícil conseguir repuestos aquí y como me dedico a cortar césped le agradezco su excelente forma de explicar

I've got a zt2800 that the oil filter stud is stripped out bad. It can't be rethreaded. What would have to be done to replace the oil filter stud?

Thanks for the tips. (Thanks also for leaving the Daaaaaaaaad!! in the video. Cool kid)

I have one of these time cutters zero turns. But the linkage from the handle to the drives is very sloppy now. Is there a way to get that play out??

Can I use the old seals,or do I have to get a kit?

can you tell me which is the pump am=nd which wheel motor nd which goes where? I seemed to have missed that in my teardown vids. I have one that has 5 pistons and the other has seven.

i have a zero turn like the cub rzt 50 you worked on . i rebuilt the right side trans axle with new parts and it works fine. i then rebuilt the left side trans with new parts and it does the same will go for a bit and start slowing down and wining. what do i try next i am at the end of trying.thanks dennis

Did you need to change all of the seals?

What brand/model hydro was this?

So im getting a rattling sound from my left pump. It works a lil, but not enough to move more than a few feet on flat ground

is this the same sort of "sealed type" unit that's not serviceable? I'm looking at a hail Mary pass on a cheap john deere with the same issue

Question what will it cost to rebuild a transmission on a toro zero turn 50 inch?

Is this the same for my ariens mini zoom 1540 has issues going up hill I just changed the fluid still slips

Disculpe soy de Perú tengo un pz60 cuando calienta suena y no avanza q partes se debe cambiar principalmente

I have found that you can use a ultra sharp and honed flat wood chisel and slowly remove the step. This has worked for me numerous times. Just adding a little help from my experience.

I have a John Deere Z535M and right side will not move forward or backward. Happened without any warning. Just finished the yard and right side suddenly stopped working. Left works fine. Right handle has no play in movement, moves just like the left side. Has oil and no visible leaks. Hoping I don't have to replace the whole transaxle. I did notice when I have the engine running and both handles in forward position, left moves and right doesn't. I can move the right side hub forward and reverse like it's in tow mode. Same when handles in reverse. When I turn the hub, it feels like it's moving inside the transmission. It is a sealed transmission. Any suggestions greatly appreciated. Thank You Sir.

Would you have external leaks if you have this issue?

I was wondering if that hydro transmissions has a drain plug. And does it have a filter. If it doesn't have a drain plug , I would put one in it. That fluid needs to be replaced every 500 hours. Thanks for the information and video.

how do you unlock the transaxles so you can role the tractor without it running?

I repaired 1 from this video lasted 4 weeks 1 acre lawn weak again any thought would help please

Tried this on my 04 timecutter and didn't seem to work. It goes forward fine but wheel doesn't rotate in reverse. When I disengage it, the wheel moves freely in both directions. Do you know what might be causing this?

In these intergrated hydro systems, do you use motor oil or hydrolic fluid I have a toro time cutter RIGHT side weak pump

Hey Double Wide Excellent work. Replacement of individual units are a ton of money. I’m not a big fan of these Cub Cadets. The decks are too flimsy. Have you done any of this on commercial units like BobCat.

Very informative. I was wondering, is there a way to drill/tap a drain plug somewhere to make this transaxle a little serviceable?

Actually I have the same problem. I attempted to fix it but disassembly stopped me. Removing the pulley was impossible. I found a used pair of transmissions and made a 4 hour round trip, $28 fuel and I was all set!

What is the best oil to use for the pump

Just a question about sanding out the scratches. Using the wet /dry sandpaper, wouldn't the sandpaper cut faster if you use water instead of oil? Maybe use oil on the last couple of finer sandpaper.

good job

Curious have you ever put a bigger drive under a cheaper mower like the cub or is it even possible?

I’m having to rebuild my drive motors at 175 hours. I really think they could use a harder aluminum metal. I also found a lot of dirt inside coming in through the vent tube I suppose. Heat, dirty oil and time seems to kill these motors.

I fix and rebuild equipment as a retirement hobby. I don't have a good history on stuff I get usually but if I overlook something or fix it wrong, I'll fix it or give the money back. I think you know your buddy got took on this one. He should call the guy and let him know it failed. If he's honest he may make good on it.

Good video!!!!!!,,,,,,Smart Guy

Good tips, I think the only thing holding anyone back from doing this repair is fear of screwing it up. But it is going to fail soon anyway. Give it a shot.

You didn't have any trouble with needing to replace some seals?

Great video. 👍

I had a thought and never have tried it but the deeper grooves that you can't home is it possible to fill the grooves with jb weld and then fine sand that? I meant hone not home

I’ve used a lot of India head cement in my life Works great to but hard to find now days

The Toro is actually called the Timecutter. BTW, those 2 Permatex products aren't meant to be used together because of their different formulations. You should use one or the other not both, actually the 'Right Stuff' or Hylomar would be the proper product. That aviation stuff doesn't set up like the silicone and might leak with right stuff on top of it.

what model transmission is this

Hey Mr got the same problem where do you live can you fix my

Im going through the same thing im going to try it

👍 nice

How Much Do You Charge For You To Do This Repair ? Thanks .

5:45 A record ! What size. Which rpm ? Just joking. Can this be done for a hydrostatic transmission without affecting the tolerance ?

Did You mention in a previous vid not to turn these around on a hard surface because the wheels need to slip?

Do you think some of the wear could of been caused by lack of maintenance? Not Changing hydro fluid? Great tip and video as always? Stay Safe. Stay Healthy!

Sorry i could hear where u get your parts from, can you let me know? Thanks

Wonder if this would work for the k46 transaxles

Forgot to ask you as to which brand has the best reputation for the longest life ??? Thanks

Good video but, Scag Turf Tiger, Tiger Cubs .. 👍👍

How much would a machine shop charge to resurface the center section plus the pump and the motor? I suspect it would not be a cost effective solution if new parts were available.

What is the best oil to use for the motor

I have never had any problem with my briggs,my sister a has a Kawasaki on her mower and it never runs.She burnt the starter up trying to get it to run so it's been sitting for three years.

Did this twice, did not work either time, looking to buy a new one

Hey Doublewide will you pick up in Quakertown?
