ZERO TURN MOWER REPAIR how to replace the pumps and wheel motors 

Straight ti the point man thank you! You are the ONLY one with the repair video for this. Bought a used one from marketplace and as always, something is wrong lol. I believe the pump is good but the wheel motors on this same exact model Gravely are about gone. Thanks for this video on the repair for in case the pump needs repalced.

Well done.Straight to the point.Thanks for posting.

Thank you for shooting this awesome video, reckon I need to do the air purge proper still.

Nothing cooler than a mechanic riding around inside the shop on a lawn mower, yelling: "Whoaa ho ho"! :P

Tks Trey very well explained, tks for your video

Extremely well presented!

Great video. I learned a lot. Thanks.

Your very smart mower medic keep up the good work god bless you

Nice job I'll be replacing the motor (just ordered it should be here in a few days) On my Toro Z420

Thanks for posting!

Great Job!! wow only took you 4 hours. I would take me all day.. LOL Nice work!!

PURGE THE AIR BY JACKING THE REAR TIRES OFF THE GROUND AND STROKING THE HANDLES BACK AND FORTH TILL YOU SEE NO BUBBLES IN THE RESERVE TANK ( MAY TAKE UP TO 1 HOUR) THEN AFTER THAT LET THE UNIT SIT FOR 24 HOURS

thank you! great video!!! i am now subscribed!

I have watched every video I could find on hydrostatic transmission problems with zero turn Mowers and the one common thread that I have found that is present with all of them is the Mowers are ALWAYS NEVER CLEAN. You can tell that they have been maintained at the minimal level if not poorly maintained. People who clean their Mowers and equipment do not have near as many maintenance issues as those that do not. I think the biggest culprit in most hydraulic failures is contamination from outside particles. This is also backed up by research and my experience with operating heavy equipment. Hydraulics have to be inspected and maintained on a regular basis or they will not hold up. Not changing fluid on a regular basis and not constantly inspecting for leaks will cause the hydraulic system to degrade exponentially. Just my two cents...

Thanks for the info man. Very good video and information! Lol wish I could've found this before I spent almost 700 dollars on a new wheel motor and labor

Hey Jeremy, my kinda video. When you got some grunting and tool dropping you know that's a real mechanic. The video work was good as you could make it. I like the fact that you showed the steps and didn't show the whole job (as you said that would be about a 4 hour video). What I'm really interested in is the cost for all of that repair. I have a Gravely that is similar to that model and it veers and since there is no service dealer in the area it has missed needed servicing. I'd like to get this thing back into service but I don't want to be taken for a ride on the cost. Thanks again, good job!

Great video Thanks

Fantastic !! That vid was jam packed with info ,too bad it wasn't longer. If you happen to do another hydraulic system ,would like to see how the bleed process is done.

Nice repair…👍👍👍

So far so good

Great Job! Marathon Hydraulic Motors. Wheel Motor Exchange.

Good job mower medic

i will do a bleed video soon......yeah it was kinda short and to the point..... if a repair video gets too long in length people start getting borde lol.....have a great weekend!!!

Thanks for the video Jeremy. Just picked up this model Gravely with 440 hrs. No signs of pump trouble yet, but have this video when it comes time. How do i tell if my mower currently has hydraulic oil or 20w/50? Is hyd oil much thicker? THanks for the help!

hey jeremy i recently picked up a 07 gravely hvz2350 zero turn when at full throttle going forward it goes real slow any advice would be great . thanks

Thanks for the info...

Both hydro gear and Parker-Ross say to never open the hydraulic system unless a failure or leak is evident The most I ever do is replace the filter evey 1000 hrs and top off the reserve tank

this is a good video!..

Great video! Question, what does your shop use for reference? Do you have something like AllData like the automotive shops have to show mechanical and electrical breakdowns and reference diagrams? Or, is there such a thing?

man that guys putting some good money into that thing

Great video awesome explanation,,,my question is I’m working on a 1996 hustler plow tractor,,my right side handle does not move any more,,I thought it was the wheel motor and I replaced it and the machine still won’t turn right,,any advice? Thanks

wow i learned alot. now imma start looking for zero turns with bad hydraulics. and replace the pumps..

Do you have any vids on the pump and wheel motors for a 2009 grasshopper 725D?

Do you know what type hydraulic pumps are on a Massey Ferguson ZT-29 zero turn mower and would they be able to be replaced with any other type?

Great Video!! I have a 2004 Hustler Mini-Z and after having it "Serviced", I had nothing but problems. Both drive pumps went out at the same time. Can they be rebuilt or should you buy new? Bought a new Hustler and would like to fix the old for a back-up. Any suggestions?

Enjoyed the direct and to-the-point presentation. (You didn't know I could spell big words like that did ya?)

Changed out wheel motor and hose's on z master 150 know reverse is forward and forward is reverse

Hi Jeremy I recently picked up a 2009 Toro Grandstand with only 412 hours it mows awesome. my issue is that when I'm backing up the Rt side is weak and slow. I've looked at the normal adjustments and don't see anything out of wack.. I've read in some forums that this was a common problem with this model.. any ideas or info on a fix would be greatly appreciated.. thanks

Nice video

Jeremy you said the wheel motors were the same no left or right ? is that right ? I have a snapper pro s200x and the motors have different # for LH & RH . have a seal leaking on the LH Motor out the shafts deal having trouble finding a seal kit that & one that is affordable any suggestions. also can you use regular 20w50 ? it's a HGM 15E 3138. Thanks ww

I need some advice on rebuilding vs replacing. I bought a 2010 gravely 260 z and it has a bearing squealing intermittently on then right hydro. Do you think it’s rebuildable?

Hey mm1 thanks so much for the video! Great help! Where did you find the parts for this? My 32" Gravely zero turn just started spewing oil from where I believe is the wheel motor. Do I need to replace the pumps too? It has 830 hours on the motor. Is it worth paying for the parts? Thanks for your help

Rebuilt the hydro gear then purged the system when up on stands works well back and forward but when put it down no power in the wheel any help thinking maybe the wheel motor is no good

Jeremy, trying to put the drive belt back on a Gravely 152Z hydro turn mower. What's the trick to treading it through? It seems to small to fit. Thanks! Frankie

Very informative video. I am hoping that this is not what I have to do. My Husqvarna zero turn recently had the idler pulley break. I disengaged the freewheel so I could tow it home. After getting the pulley put on, and re engaging the freewheel, the mower went very slow. After troubleshooting, I determined there was air in the line. After purging the transmission several times, it ran fast again. Only to discover that my right hand turns are very slow when I use the left lever. When I push the left handle (which turns it right) all the way forward I slow down. I have even purged just the left side hoping that would fix it but it didn't. I ended up cutting using left hand turns more often to get the job done. Can you tell me if you think it is this motor? Thanks, Erica

great video jeremy thank you. I have a GRAVELY ZT 1540 WITH A 17.5 HP KOHLER that has locked up. taken off the head and the top case to inspect lower drivetrain and piston top and cylinder wall. No broken parts or scoring of cylinder wall . all that is left is the crankshaft or rings right? could the hydraulics keep me from turning over the engine? thanks tom from KC.

Man could I do with you here for a while, you are one very talented man. you work so quick and efficent. I have spent a day trying to bleed my husqvarna iz4821 and while the oil in the res tank starts off clear it soon becomes milky with tiny air bubbles. everything is tight and I have purged heaps of times. I need a Jeremy! Where can the air be getting in?

ALWAYS GO OEM AS THEY MAKE DIFFERENT CC PUMPS GOOGLE THE NUMBER OFF YOUR PUMP AND ORDER THEM ONLINE OR FROM A REPUTABLE DEALER

Question for a mower expert: I have a scag wildcat with play in the left stick. The left side also goes slower than the right and tends to lock up the wheel when pulling back on left stick. Pump or wheel motor?

What machine are you doing this video on? I can't seem to find pump numbers on my pumps but looks like the mower I have.

Hey man great video...quick question for ya...just picked up a free Dixon ztr428 zero turn mower....it works prefect runs strong and cuts perfect too...it has a new 14.5hp Briggs intek engine....my question is...what do you think of these Dixon mowers....any huge problems with em...cause I'm thinking of keep it for myself...never had a zero turn b4...any advice would be awesome...ty!

we use the manufacture shop issued online manuals

I have a scag superz that has started to do the same ,i am using 20/50 but at first when i got the mower it was fine the seller had let it set for 5yrs and now all kinds of racket! Do I dive off into the drive motors or look at pump?

Would love to see a hydrosteer rebuild on a grasshopper or old woods zero. Them things are way expensive!!

Is there any type of adjustments on these drive systems?

What a great video! I have the same machine, the right one was making a noise and acting up at times so I sent for a new one, they sent me one with no fan spout but has the same part # ? I told them it was the one with the fan on the right side, could both be the same part # they said it was the one for it` any help would be great. Thanks

Are you still answering questions? I'm thinking about replacing the exact same thing on my gravely. Where is the cheapest place to get the new hydraulic pumps?

I have the same issue with one side. Do I need to replace both the pump and the motor? 20w 50 was used. If only one how do I know which one?

Wondering if you were ever able to find out what type hydraulic pumps are on my Massey Ferguson ZT-29 zero turn mower or if you would know why one side pulls slower than the other side?

Hey bud i have to replace one of my hydro pumps left side on a Dixon grizzly 60inch ztr they quit making parts for it but im wondering if you think these gravely pumps might interchange they look almost identical, let me know you thoughts

Do they put bypass valves on these so you can push the unit? I don't see any on my compact pro. Also, how come they don't put a fan on both pumps?

2008 gravely 260z how do I lift the seat?

I need to remove my wheels on my walk behind. Its hydro pump and wheel motor driven like the one you just worked on except mine is a 48" MTD PRO Walk Behind. There is 4 lug nuts and 1 center castle nut. My question is, do I only remove the 4 lug nuts to remove the wheels? I did just that and couldn't get them off. Then I removed the castle nut and still couldn't get the wheels off

Hi Jeremy. I have a Bunton zero turn that is chattering on the left side. The unit is still pulling and has good power but is weaker than the other side. My question is how do determine if it is the pump or the wheel motor? Thanks for your time. I think it is the wheel motor but not sure.

nice job my husqvarna z4822 zero turn those same noise when I turn on the left side can't you give me a tip please

great vid ! Hope my issue is not with hydraulics but... I have an Exmark lazer z hp and the right steering arm is about 5" out in front of the left arm. Mower moves great and turns accordingly but the arms not being even is weird. What would be the cause and what is the remedy?

What oil do you put in hydro trans axels in garden tractors?

Jeremy, Great video. I have almost the exact situation. The right side pulss like a mule. The left side is a complete different story. No power at all, and the deck will not raise or lower. Feels like I'm a Nascar driver making nothing but left turns. Would you think it is the pump or the actual pump, or both. Should I start with one or the other?

hi, I have a 2011 toro z master 3000 series with a 24 hp Kawasaki. The mower runs and cuts excellent, we changed the hydraulic oil and hydraulic filters last week. The left side turns perfect, but the right side turns terrible and there is a delay on turning right. When I turn right, it seems to be harder and puts more force on turning on the right side only. can you please help ?

i have a lesco zero turn rebuilt pump ive tried to purge system cant get fluid out of the high side of pump tank full and filter is also should i fill the pump up first and try or do you have any ideas

Would it be almost the same for a 2015 52in bobcat stand on mower I think my left is bad. And if so do I do both sides or just the one side

Hey Jeremy... just recently acquired a Woods R2048 zero turn that seems to run well (motor on it at least) but has it's share of problems. First of all doesn't have much power going forward (left side has more than right), I can go back and forth to gain power and will eventually go okay on level ground but must do most inclines in reverse. Someone replaced the original motor with a 14.5 hp and I'm wondering if that would be giving me the issues I'm having that seem like hydro problems? I think I will start with changing fluid and filters because I don't know if they've been changed or not, making sure no leaks anywhere and purging system of air. Any other suggestions???

Great info Jer, that's a lot of work, if I may ask how much labour does a job like this cost the customer asides from all the new parts ???

Hey I have a 2006 Dixon Kodiac w about 650 hours. Just started having problems with the right wheel getting weaker than the left wheel. How can you diagnose whether it is the hydraulic pump going bad or the wheel motor?

Where do you get the parts from... im looking for a gasket set for the hydro wheel drive

I'm trying to change the motor on a zero turn mower, new Holland, and I can't get the pully off the motor can u tell me how to do that???

I have a 74” Dixie chopper the right side will barley drive and whines really bad. I took it to the shop they said it was the pump. I had them rebuild it and it changed nothing now they say it’s the wheel motor but I have to change them both. Curious what your thoughts are. I’m in $800 now and they’re saying an additional 2k from a previous install on someone else but if they can do it for less they will. Meaning I can get the parts at cost.

HI Jeremy. Time to change Hydro trans fluid. 500hrs Simply drain tank and replace filter? What about remaining oil in motors and lines? I have the same Gravely you repaired in your video.

Hey! My motor wheel is not working , can i put a new motor wheel without changing the hydraulic pump?

Hi Jeremy. My Ferris is1000 21hp 48 inch have similar problem on the left side. Do not go forward. Only go back fine. Do you have any idea what wrong with it.

I have a scag zero turn mower and when I back up, there is a slight delay in the left wheel. Do you know what could be causing this? Any info will help. Thank you

I've got a cub zero and the left side is weak . Can you buy a rebuild kit for the hyd pump and kit for the wheel motor ? I'd like to rebuild the pump and wheel motor since the pump is $450 THANKZ

4-6 hrs. If transaxles the about 1-2 hrs per side

Hey Jeremy, the noise at 1:01 that the left stick is making - my YazooKees 48" ZT Max is making the same noise. Is that a pump problem, or wheel motor problem?

I feel u bro I work at a golf course I also do small engine mechanic we have a sand pro for the sand bunkers the pumps wer acting up told my boss when thay bought new pumps that thay use 2050 synthetic oil he sed he gona put hydro oil I was ok do as u like the pumps did not last that long the pumps cost more than the unit is worth so no we have a 300lbs paper wate in the shop ..... sincerely... RIGO SMALL ENGINE REPAIR some people are just hard headed thay think thay know it all thay don't no shit

Where do your old pumps and motors go? I'm looking for sum to deconstruct? Hydraulics is cool...man

Hi we have a Dixie Chopper 72" cut works fine until it gets hot then the left side it won't to jump going up a hill or a hard pull ??

How do I get the wheel moter fitting out? Does it have to have the wheel moter off?

Thanks for the video but not sure this is my problem. I have a Husqvarna CZ4817 zero turn riding mower that I just replaced the drive belt and ty-rod. It worked fine for 12 hours of mowing (4 different times). I was mowing last night, went to use the right arm to back up and it would barely move backwards. It moves forward just fine and turns just fine. It just want back up on the right side. Left side works fine in all directions. Please ya’ll any ideas on what to look for, where do I start? Thank you so much in advance.

Is it the same process for an exmark laser Z zero turn. The wheel motor is shot on the right side.

I have a Gravely 260z and have replaced the Hubs and can not get the hub all the way up on the spindle to seat, stops short of the cotter pin hole by 1/8" or 3/16", the hub nut goes on with a couple of treads showing. Had to use a car hub puller to get the old one off. I did grease the spindle shaft before installing the new one and did align the keyway. Any thoughts

jeremy seeing if you can help, I have a swisher ZMax ZT2660 with eston transmission system. I put regular hydrolic oil 32W in the reservors and now it starting to drag. any suggestions on how to fix problem. did i use the wrong oil. what type of oil should i use in this eston transmissions. your insight would be deeply appreciated, thanks, John

good job.do these use a pump for each motor?uses two pumps and two motors?

Another good tutorial ....can't these pumps and motors be rebuilt?

My tire is rubbing on the frame and I think that's why my wheel motor went out any idea why it would be rubbing i bought the lawn mower used I replaced the wheel motor ..but it's still rubbing on the frame on the right side the left is fine..

I just installed a new wheel motor on my country clipper zeton and it is the joystick model as far as getting the air out of the lines is there anything specific I need to do it seems like even with the joystick in the neutral position pushed all the way down with it on jackstands the wheels still turn

Sure is a lot, still haven't gotten to my mower. Hope to replace mine soon, the price is a lot!

I have a dixon DX254.. Replacing the Pump belt that snapped so i dent get to see it installed... Does anyone have a diagram of the belt routing? Or a top down picture would do... The idler wheel does not seem to be on the same plane as the other pulleys? did something get damaged?

20w50 synthetic motor oil only

Good Video.
