    JD 2040 (year 1980) rock arm (bushhog) stuck in up position

    There is a rate of drop control under the front of the seat. Some models had a lever and some had a bolt head that needed a wrench. Make sure it didn't get turned full clockwise. That would prevent it going down. Have you tried moving the draft control lever as well as the height control? Draft...

    2040 hydraulic problems

    Technically, there should be no flow through the valve when steering is not being used. That would mean no temperature increase at all. With all new seals and installed correctly(those lower couple of orings can be challenging to get into correct grooves) the only other thing would be leaking in...

    6110 with 620 loader

    THe detent you feel to the right is for the regenerative circuit for dumping heavy loads. If you have a heavy load in the bucket, the weight tries to extend the cylinders faster than the hydraulic pump can keep up. The regenerative circuit helps alleviate that problem. For the float issue, It...

    1963 2010

    There are several different versions of 2010's and different shifters. From your profile picture, I think I see you have the shifter on right side of dash. If so, then it could be adjustment or could also be worn pars in shift linkage. There are adjustable yokes on shift rods to shorten or...

    The tach is mechanically driven with a cable. Try disconnecting the cable from the back of the tach and then start the engine. if inner cable spins, then the tach is bad. If it doesn't spin, then the cable is bad.

    1963 2010

    The distributor and coil are 6 volt. There is a resistor in the circuit that cuts back the voltage. THe carburetor adjustments aren't so cut and dried. It should idle about 600 rpm. You need to adjust the idle mixture screw so you get a nice smooth idle and the load screw needs to be rich...

    PTO issue John Deere 4120 stops under load

    THe filter and screen could be a problem and is a good place to start. If other hydraulic functions are working OK, I doubt that will fix it though. Sounds like you have low pressure to the clutch or clutch could be worn. Low pressure can be caused by a bad solenoid, blown orings on solenoid...

    John Deere 4630 transmission

    Unfortunately the 4630 is a larger framed tractor. The 4430 transmission will not bolt up and I don't think any of the gears inside are the same either.

    4630 SCV adjustment

    I have adjusted hundreds of these over the years, but I have always used the special tools and dial indicator to adjust the valves. The 2 return valves get adjusted to about .021" clearance and the pressure valves about .060". You need to have some method of holding the valve you are adjusting...
