    New-to-me 750

    As some of you know, I acquired a JD750 CUT yesterday.

    Here's where it stands so far:

    Once I got it home, I installed a good battery to check the electrical and starting system. The starter would not engage. After some testing, I determined the problem was in the starter. I disassembled it and found corrosion at the solenoid contacts. Once I got it clean and reassembled, I bench tested it and it now works as it should.

    With 1190 hours showing on the Tach, other than maintenance items, all parts look the be original to the tractor, even the tires.
    The engine clutch is stuck. This usually happens when the tractor is set up for an extended amount of time, with the clutch engaged. The high humidity down here isn't much help either. I'll unstick the clutch after I'm done servicing the engine and transmission/hydraulic system.
    Below is an example from the JD owners manual touching on this subject.

    IMPORTANT: Avoid damage! Clutch must remain disengaged when tractor is placed in long term storage. Corrosion can cause the clutch disk to seize to the pressure plate and the clutch can no longer be disengaged.


    I don't have the correct engine oil filter, so I'll have to purchase that, along with a fuel filter and air filter.
    I also drained the fuel tank and to my surprise, was very clean. I'll replace all fuel lines. They were not leaking, but the outer surface is dry and cracked. I have a couple 25' rolls of 3/8" fuel line here in my shop.

    I removed the engine oil and transmission/hydraulic oil drain plugs to allow the oil to drain overnight. Next was removing the suction(sump) screen from the trans case to inspect. The screen is in good condition and is clean, with no metal, or fiber material present.

    I tested the engine coolant and is good for -20°f. The coolant system test was good with no leaks. I'll retest after the engine is run to operating temperature.

    Radiator cap looks to be original and the seal is still in good condition.

    Thank goodness you started a thread for this 750, I was expecting a lynch mob would be sent out for you if you didn't.


    Although by the sounds of Titleist1's post above, you may not be in the clear just yet. Better lay low.

    OK, mr. antique TV picture tube look alike avatar. I guess I'm following rydplrs's lead at close ups. Besides, it's to leave you in suspense. Anyway, I posted a sneak peek earlier. I'm guessing you didn't see that. Or, could it be a touch of Dementia creeping up on ya?

    When I get the 750 running and out of my cramped shop, I'll post a Full Frontal and Profile.

    Oil, air & fuel filters from one of my friend's NAPA store. He was so excited to see me buying from him, he gave me a discount.
