New Member John Deere 855

[tab108]

Just bought a JD 855 that had been sitting for several years. It is 4wd and has a 70A loader. Just changed the oil. Hydro fluid looks good. Cleaned the air filters.

Problems:

4x4 does not work (shaft turns, but not the frontend, oild drained and no metal found)

hydro forward and reverse pedals hard to push

throttle lever falls down and you have to keep pushing it up

three point hitch lever falls down and have to hold it up

hydro control for loader works for up and down, but tilting the bucket gives me problems, sometimes works, sometimes not (linkage issue?)



Any ideas?


Thanks

There is a specific Hydraulics forum here on TBN. Perhaps you might get some answers by reviewing that section and posting your inquiry there? BTW, Welcome aboard and Good Luck.

I moved your thread to the John Deere Owning/Operating Forum.

The 855's front axle has a dubious history of wiping all the teeth off the pinion gear and/or shearing the bolts that attach the ring gear to the differential carrier.

No, A John Deere with front end troubles? Can't be

Tighten the throttle lever pivot bolt, there should be a set of friction washers to tighten against it. The pedals on those are stiff to push. I would be worried if you said otherwise. The front drivshaft will turn any time the tractor is moving because it is direct linked to to the shafts and tires. The question is weather it turns with power. Raise up all four tires and test drive with it engaged and disengaged. Then see if the shaft still turns. The linkages on the joystick get kinda screwy at times.

Could also be the same problem for the three point lever moving as the throttle lever.

Check the hydraulic quick connections. They should be fully engaged. Make sure to have the loader buckt on the ground and not residual pressue in the lines (tractor off, wiggle the lever in all directions to relieve pressure). These quick connections are notorious, but an easy fix.

I just picked up an 855 today. want to check it out tomorrow and maybe change fluids. any tips on fluid change and overall advice to make sure tractor runs well? no manual yet. first tractor ever.

I changed the engine oil/filter first thing. I just bought a hydraulic filter and 5 gals of the JD spec off brand. Waiting to get time to change that too. I have been using the heck out of it though. Works great. I am very pleased with mine so far. Hope you are too. Just remember, they are a getting old and things will break from time to time....just don't get discouraged.

I've been using off-brand hydraulic oil as well. The only problem is the only off-brand I can find is J20C spec (Hy-Guard). The tractor really should be using J20D spec (Lo-Vis Hy-Guard) and I notice a bit of a performance hit. Next time it gets changed, I will pony up and switch back to J20D, which I have only been able to find at a dealer.
