John Deere 110 backhoe hardly moving

[boggen]

TLB on some units have a funky setup when you remove backhoe to access 3pt hitch, you need to reconnect the hydrualic hoses up the correct way. hook them up wrong and you get nothing.

============

make sure you are checking correct "fluids"
A) 1 for oil in engine, (dip stick along side of engine normally)
B) 1 for power steering (most likely under the hood near steering pump)
C) 1 for transmission / rear end (between your legs on the floor board, perhaps a circle you need to pop out to access dip stick. if no circle perhaps circle never got cut into the rubber mat on the floor, it might also be loacted in engine compartment just behind the firewall.
D) 1 for pto on rear end
E) 1 for final drive (what goes out to rear tires)
F) 1 for hydrualic fluid to run FEL and backhoe.

with above said
A) normally seperate from everything
B), D), F) might all be tied together under a single pump
C), D), E) might all be tied into transmissions internal pump.

===============
check the emergency break. is it engaged? are any of the cables stuck for emergency brake?

I got the 3pt to work. I'd say the 3pt was never used and there was a lot of air in the cylinder so I had to keep working it back and fourth and it finally got freed up. Now if I could only get the thing to move with some power.

I changed controller,ground speed sensor and speed sensor. Still the same. Moves but no power. You can put a empty beer can under the tire and it will not run over it. Stops it right in it's tracks.

Thanks for all the input. Anybody have any ideas on the not moving?

looking at John Deere US | Products & Services Information website. and looking at part diagrams

2914 - 110 Tractor Loader Backhoe (Worldwide Edition) - 20Feb17 ( FR DE IT ES SV )

not sure if above is your specific tractor?!??

============
looks to be a clutch that might be out of adjustment / broke.

i see some "PROPORTIONING valves" on the transmission with coil part numbers.

i see a "traction assist pedal" ??? does it lock up rear wheels together so they spin exactly the same?

 

[jpolcyn]

I have checked the proportional solenoid valves. Both seem fine. If you hold down on the difflock yes both tires will rotate at the same speed. But it still has no power behind it.

the clutch maybe slipping out of alignment. it might just have enough friction to turn the wheels, but as soon as you apply external force the clutch slips and you go no were.

HST like transmissions might have internal leakage as well or stuck. and when so much pressure builds up. leaks are happening internally not allowing pressure to be sent to the wheels.
HST also should have some sort of "pressure relief valve" internally and may not be set correctly.

have you tried other gear range selections? low, medium, high? (not sure what your tractor has), does tractor also have another gear shifter for say 1-3 or 1-4?
hmmmss try going in reverse and forward in each selection of gear.
check the linkages for the shifters. are they even shifting the transmission into other gears.

on some tractors, there is a shuttle shift leveler by steering wheel that dumps the clutch, then a lever on the gear shifter/s and then possibly another button on the FEL joystick that also dumps the clutch, and other tractors just have a foot pedal clutch with linkages. is the clutch linkages that actually move the clutch set correctly?

it has happened wire harnesses plugs come loose. and mice eating up wire insulation and shorting the wire out.

 

[jpolcyn]

Thanks for the input. I jacked the back tires off the ground with the outriggers and they will spin in all 3 gears just fine. H,M and low is what it has. No clutch or anything like that.

Update:

Had to take it to JD as i am at a lost besides the hydrostat going out of it. Should know what they have to say today.

Thanks

 

[buickanddeere]

Any pressure test ports ?

 

[jpolcyn]

Yup. It did not build the pressure like it is supposed to.

 

[jpolcyn]

Hydrostatic transmission is out of it. Get to split it open now. Such fun... Not.
