    John Deere 650H moving slowly

    Beware if you’re going to calibrate the machine and you don’t know whats wrong, if the machine fails calibration it won’t move until you fix whatever is causing the issue. So calibrate it somewhere out of the way. Might help to check charge and brake pressure and do a PCP test first...

    700J speed limited

    609.09 is an issue with the CAN communication between the SDM (monitor) and TCU. Usually this is a blown power fuse into the TCU or can wires rubbing somewhere. Yours is intermittent so I’d guess wiring. The 91.x is seen on machines with the old throttle knob. Usually see this when people over...

    John deere 950j dozer

    The 950J machines are the same as the Liebherr 944. John Deere used to have a joint venture with Liebherr on the 950J and 1050J. The 850J and smaller were always built by Deere in Dubuque. The newer 950K and 1050K are also now built by Deere in Dubuque. With that understanding, the 950J is...

    Advice on purchase of a Deere 450-650 size dozer

    I love the 450 - 650 sized dozers, but I’m biased. These machines are great for the woods. Get an H or newer, definitely narrow pads if you have a lot of rock. You’ll only be able to get a PAT on these models, but there are different blade widths. If you can find a good H or J, they won’t have...

    D-51px22 Komatsu reviews

    What are you doing with it? The 700K’s a hot rod, the newer K’s have more power but the transmission is the same. The D51 is a good little dozer and they have great visibility out the front. They’re not service friendly from what I’ve heard. Some guys that do a lot of clearing don’t like them...

    850 J cooling fan air flow direction?

    Fan should be blowing out during normal operation. You've got the right fan and fan motor. JDParts calls out AT372688 for the motor, but its a substitute for AT304104, so same part. Make sure your lines match this diagram from the pump to reversing valve to motor.

    JD650H dozer major hyd oil leak under pump/ transmission

    Just sitting in neutral the transmission charge pumps dump into the hydrostatic cases. Thats a good amount of flow and could drain the reservoir. Its your transmission reservoir thats emptying? Is your hydraulic reservoir fine? Could be a crack in the transmission pump housing. There is a...

    Deere 450h hydrostatic problems

    Someones been through the dozer capstone, haha! 0-5psi differential is good, 5-15psi you can adjust, more then 15 psi you replace the PCP. What exact step of calibration is the machine failing? Thresholds, low speed, or high speed?

    850 J cooling fan air flow direction?

    If your fan is running backwards, its not cooling enough. Fans arent designed to run opposite direction all the time - you give up some cooling efficiency, but purge out the coolers. Thats why the fan reversal cycle time is limited. Assuming you got all the right parts, you might have a line...

    JD 750C wont move.

    Here is a component location, your machine may be a little different if it has pedal steering but the FNR and steer sensors should be in the same general area. The wires should’ve had labels on em but a 750C is an old girl so they may have worn away. The electrical connectors should have the...
