The hydraulics for my front end loader & backhoe work fine,but my tractor has started jerking when traveling.Is there another filter in play besides the suction side filter.I bought this tractor new and it has served me well.It still works but the problem gets worse at higher rpms.New to the forum thanks in advance.Wayne

Welcome to TBN, wayne. Does the tractor jerk in reverse, too? Steering and 3pt lift work?

I think I would set up an appointment with the dealer and plan on taking it in. Getting this fixed before you have a major failure might be the cheapest thing you can do.

There are potentiometer's (sp) for the forward and reverse pedals that can fail or need to be readjusted. However, it would be very unusual for both to fail at the same time.

Your situation sounds like the problem is with the main hydrostatic transmission. Given that you don't have problems with either the steering pump, the main implement pump and the auxuliary pump.

I agree with Steve - this is not likely a problem that you're gonna fix with a weekend and a couple of beers. I'd take it into your dealer and have them work thru the diagnostics.

Wayne, I am having the exact same problem with my 110 TLB. I just spent the day changing the hydraulic fluid and filters and cleaning the suction screen. When I drained the fluid it was 2+ gallons less than the 9.7gal shown in the manual. I was sure this would fix the problem, but it didn't. It is sluggish and jerks in all three speeds A, B and C and in 4WD and forward and reverse. All other hydraulics work fine - bucket, hoe and steering. I spoke to the dealer yesterday and he indicated I would need to bring it in if the filter and fluid change didn't correct the problem. If anyone has any other ideas before I truck it over to dealer let us know.

Isn't there a procedure for calibration of the hydro pedals? I believe there is on the 3000 and 4000 series.

Briches let me know what you find out please sounds like we have the exact same problem and I can,t swing a trip to the dealer at this time.Thanks,Wayne

Success! Problem was solved by replacing the speed sensor, part # lva17409. Cost $61 and labor $119. I took the machine to dealer last week and left it. Mechanic told me he had just repaired another 110 TLB with the same problem. He first thought it was a hydraulic problem, but when he hooked it up to computer it showed that the sensor was "sending out the wrong frequency"??? Don't know what that means, but the new part fixed the problem. Don't know where the sensor is located or if it is a repair you can do yourself. I'd call your dealer and ask. It's not an expensive part. Good luck.

Thanks, for your reply. It came in handy, as I am having the same trouble with my tractor as you were. I will take your advise and hope it works.

You can isolate the sensor by unplugging it and then drive the unit. If the jerking stops replace sensor. The sensor is located on the right side of the flywheel housing at about the 2 o'clock position.

Hope this helps

Looks like I have the same problem...

Only way to move is by using the creeper function... all other hydraulics/engine seem fine... just no pedal forward/reverse... a couple of times it was jerky yesterday... kind of like lurching or surging.

Had no luck getting through to Parts or Service at JD this morning... only one man in each department today per secretary.

Good thing the 110 has the hand operated creeper function otherwise I would have had to leave the tractor at the job site.

Mine has the surging or lurching problem but last weekend I tried adjusting the throttle position sensor and set one way there was no pedal function, the other way it was lurching terrible. Guess I will try a new engine speed sensor since it is not much money.

I have one coming... should be here Monday/Tuesday.

I will be one happy camper if that takes care of it!

Surveyor 2 · Sep 10, 2012

The engine speed sensor solved the problem. No more surging or bucking! Thanks for all the help.

ultrarunner · Sep 13, 2012

Success!... the speed sensor took care of the problem... Tractor is back in service and what a relief!!!

Mechanic had me worried... said it sounded like the transmission or hydro going out...

Had to order the part because local dealer does not stock since there is no demand.

Total out of pocket about $80

TBN saved the day again!

ugo4it · Sep 13, 2012

Any details on how to do this repair? can it be done yourself or does a dealer need to hook up computer to set it up? Any pictures of location and sensor. I don't have the problem but it sure seem like allot of TLB get the problem, so it would be good info. to have.

ultrarunner · Sep 13, 2012

The sensor is a small probe with a short wire pigtail...

One 10mm bolt holds it in place and it is located above the floorboard on the bell-housing at about 2 o'clock near your right foot when sitting in the driver's seat.

The hardest part, and it was hard because I have large hands was reconnecting the wire pigtail to the wire harness lead... just didn't have anyway to get both hands in there... eventually, I got luck and was able to slip the connector together with one hand.

I had no warning lights flashing so the senor was apparently still signalling... Key off, remove and replace, key on and started and drove great.

Don't have a way to take a picture to post at the moment...

Amazed that one little electric sensor can render a big TLB inoperable...

The symptoms came on slow over the course of two weekends... first noticed a slight lurch when going forward and thought it was a quirk... then it did it again.

It got so bad the tractor basically refused to move with the pedals...
