what causes zero turn mower hydro pumps to fail

• #ane

I was mowing the lawn this night and without whatsoever noticeable upshot, the left hand drive became sluggish of a sudden. It wasn't completely inoperable, simply I would give the left side "total throttle", and had to just barely engage the right side if I wanted to go straight. It seemed like I could turn and go in reverse for short distances without issue, merely that could simply be me overthinking.

I'm having trouble searching for troubleshooting info online. I'm hoping information technology'south just low hydraulic fluid on one side, but and then once more it could be a valve or the pump itself. Has anyone else had similar issues? What practise you think I could be?

C5 on the right. No idea but good luck

C5 on the right. No idea but skillful luck

What does C5 mean?

That's precisely why i'd never purchase a zero-plow...

anyway, is yours a commercial unit or residential?

I tinker with John Deere so let me know if yours is a JD...

• #vi

Might be a stripped gear/caster

• #eight

2 (ok, probably 4) of them

• #ix

If you find out let me know, my right side drive is sluggish.

Sluggish, like a wet sponge.

• #10

Might be a stripped gear/caster

Stripped gear? Wtf

It'due south probable a bad integrated hydro... though if it'southward a Deere they employ split Kanzaki pumps and wheel-motors (depending on how old / model ZT)

If it'southward a residential vs a commercial unit - drive components/parts are all but likely probable non servicable and volition require replacement equally an entire module...

Might exist a stripped gear/pulley

I would definitely cheque the spelunker pump too.

I was mowing the backyard tonight and without whatever noticeable event, the left hand drive became sluggish all of a sudden. It wasn't completely inoperable, but I would give the left side "full throttle", and had to just barely engage the correct side if I wanted to go straight. It seemed similar I could turn and go in opposite for brusk distances without outcome, but that could but be me overthinking.

I'yard having trouble searching for troubleshooting info online. I'chiliad hoping information technology's just low hydraulic fluid on one side, merely and then again it could be a valve or the pump itself. Has anyone else had similar bug? What practice you retrieve I could be?

Start thing to exercise, wait at the rod that y'all pull to disengage the hydraulic motors. Should be 1 for each side. Make certain it didn't come out slightly on the weak side. Then, very simple concept of operation. There is a single hydraulic tank that feeds both hydraulic motors (pumps) . Check fluid level first, then go to the weak side and check the filter. Each hydraulic pump has it's own filter. Replace it starting time. The next matter to look at is the pump. Each side has it'south own pump. I'd think that the valve works would be robust enough to non be an issue. I'd go with the disengagement lever as your problem. Mail an update on what you notice.

Not interested in what you're reading right at present - just need to know the brand of your ZT

Turn harder.

First thing to practice, await at the rod that you pull to disengage the hydraulic motors. Should be one for each side. Make sure it didn't come out slightly on the weak side. Then, very unproblematic concept of functioning. In that location is a single hydraulic tank that feeds both hydraulic motors (pumps) . Check fluid level kickoff, then go to the weak side and cheque the filter. Each hydraulic pump has information technology's own filter. Replace it first. The adjacent matter to look at is the pump. Each side has information technology's own pump. I'd remember that the valve works would exist robust enough to not be an issue. I'd become with the disengagement lever every bit your trouble. Post an update on what you notice.

If it's equally simple as a displaced freewheeling rod - Ranger should immediately get out and purchase lottery tickets...

Every bit far equally checking fluids on the hydros, chances are he has sealed units

• #17

I would definitely cheque the spelunker pump too.

From now on if somebody is having problem with their car I'chiliad going to suggest they check this.

• #18

Maybe that'south why he's having problems. Information technology'due south difficult to mow in a cave.

If information technology's as uncomplicated equally a displaced freewheeling rod - Ranger should immediately go out and purchase lottery tickets...

Yes Massimo, they are sealed units. They are also individual units that power each side. A seal can blow causing a leak but that should touch on both sides due to low fluid levels. I had a similar problem and information technology was a free wheeling rod out partially. Pushed information technology in fully and it runs great. I should have brought a lottery ticket that night but I was decorated cutting grass.

• #20

Aye Massimo, they are sealed units. They are also private units that power each side. A seal tin accident causing a leak but that should affect both sides due to low fluid levels. I had a similar problem and it was a gratis wheeling rod out partially. Pushed it in fully and it runs great. I should have brought a lottery ticket that night only I was decorated cut grass.

Stripped gear? Wtf

It's likely a bad integrated hydro... though if it'due south a Deere they employ separate Kanzaki pumps and wheel-motors (depending on how old / model ZT)

If it'due south a residential vs a commercial unit - drive components/parts are all but likely probable non servicable and will require replacement every bit an unabridged module...

The gear term is probably incorrect. Splined probably a meliorate term. The spline on inner diameter of a pulley. This really happened on my Deere lt180 (not a zero turn) and could only get very slowly, and when the stripping got worse information technology would non motility at all.

• #26

If information technology will only turn left, put some NASCAR stickers on it, advertise information technology in the Penny Saver , and sell information technology for twice the toll.

• #28

You must have a small yard with no obstacles. I accept an acre and a one-half with 107 trees, bushes shrubs, blossom beds to mow. Used to have 4 i/4 hours. Now with a Skag Patriot I do information technology in 1 3/4 hours, fifty-fifty with a sluggish right side drive motor.

Pretty sure i mow more you... i own 1 acre with 75' walnut trees, Hemlocks, Kingdom of norway Bandbox, and mature cherry, apple, and peach copse, ... plus I mow a 3mi loop to maintain a tremendous walking trail in town-endemic greenspace that my property backs to (pic below)... people walk barefoot on this trail... got 751hrs on my JD and adopt my horsepower betwen my legs as opposed to an engine tickling my donkey

That's precisely why i'd never buy a zip-turn...

Yes sir.. superlative of the line. It takes a beating. I bought it in June of 2017 and I've put 700 hours on information technology and so far no major bug except with the deck adjustments. Warrantied of course. I'm happy with it.

Was looking to Trade my Scag Cheetah (30HP) with 450hrs on a JD 970R, simply really cant justify it.

I'd stick with the 30hp.

It wasn't completely inoperable, merely I would give the left side "full throttle", and had to merely barely engage the right side if I wanted to go straight. It seemed similar I could plough and go in opposite for short distances without issue, but that could only be me overthinking.

Either the pump or fluid. How old is your tractor? Pumps need replaced after so many years.

Pretty sure i mow more than than you... i own 1 acre with 75' walnut trees, Hemlocks, Kingdom of norway Spruce, and mature cherry, apple, and peach trees, ... plus I mow a 3mi loop to maintain a tremendous walking trail in town-endemic greenspace that my property backs to (moving picture below)... people walk barefoot on this trail... got 751hrs on my JD and adopt my horsepower betwen my legs as opposed to an engine tickling my ass

You lot can apply whatever mower you want, but mowing that much and effectually trees without a zeroturn is like choosing to sentry motion-picture show tube TV wn there are apartment screens bachelor.

You tin utilize whatever mower you want, but mowing that much and effectually trees without a zeroturn is similar choosing to scout picture tube Television receiver wn there are flat screens available.

Tell me about the snowblower that Zeroturn volition accept?

• #37

Tell me virtually the snowblower that Zeroturn will accept?

Well, I had a neighbor who worked every bit a mechanic for farm and lawn tractors. He got a grasshopper zero plow that someone traded in and did rig up a snowblower in place of the forepart deck. That said, yous probable don't snowblow that walking path all winter, so the zero turn makes more sense to me.

Well, I had a neighbour who worked as a mechanic for subcontract and lawn tractors. He got a grasshopper zilch plough that someone traded in and did rig up a snowblower in place of the front deck. That said, you likely don't snowblow that walking path all winter, and then the zero turn makes more sense to me.

I'm a 5-fe from Lake Ontario... I'll take my tractor whatsoever day of the calendar week

At present the board has lawn porn. What will we call up of next?

The main thing I call back from my lawn mowing days was having to kicking a loose connector to the spark plug on one side every once in a while. I soon found that if my shoe was the to the lowest degree bit wet, I'd get a nice shock doing that.

I'd take raking leaves or digging a garden over mowing the backyard any 24-hour interval. At least the former ii jobs were washed in cooler weather.
