    Help with Purchasing a 1989 JD 650

    I am currently looking at purchasing my first "real" tractor. I have a 2 acre property to mow, 200 ft of driveway to clear and 10 cords of wood (annually) to haul. For the past 9 years I have used an lawn tractor with snowblower and cart (la145 with 44" blower) and needless to say, the 300 hrs on her have been hard. I got my money's worth though, thats 90 cords it hauled. However, the tranny has called it quits.

    So there is currently a goo deal locally on a 1989 JD 650 with belly mower, box blade, and a few other attachments. It appears to be in good condition and would fit my needs (maybe a little overkill....)

    Anyway, before I go and view it, I would like to know what I should be looking for.... I know to look for overall condition, possible blowby, hydraulic leaks, tires, etc. However, I am a little vague on the clutch, PTO and hydraulic setup it might have or I might need. Does it have front and rear hydraulic connections (do I need it?), does it have front, rear and mid pto (do I need it?) etc. etc. Does it have a single or dual clutch and which do I want?

    I am envisioning it being setup with the mid mount mower for mowing, front blade for clearing snow (or possible front blower) and a rear scoop style rig on the pto to haul wood into the house.

    Any help would be greatly appreciated.

    After 2 mowing seasons with a 650,, I can add that it is a nice tractor,,,



    BUT,, do not expect a lot of modeern tractor features,,
    the 650 is closer to an 8N Ford than a JD 1026R

    no live rear PTO, the mid mower is powered off the front of the engine pulley,

    All external hydraulics would be an option,, one that would be expensive to add.


    All in all,, it is a great machine because it is so simple!!

    Thank you for the quick reply. What do you mean by "no live rear pto"? I see that you have a rear mounted mower, so there must be a rear pto....sorry i am still learning.

    I don't know why it surprises me but it does, in my mind I just assumed anything built by the end of the 80's would have a live PTO.

    There are several types of pto drive.
    the 650 has one that only spins when the clutch is out.

    If you push in the clutch to stop the tractor,, the pto stops.

    My other tractor has a pto that operates independently of the wheel drive clutch,, it is "live"

    On the plus side,, the 650 does have an over-running clutch on the rear pto,,,



    And,,, the 3 point hitch is "live",,,

    They started the model in 1981,, probably never changed it,,.

    A live pto was an expensive "add",,,

    I see...lots of good information. The overrunning pto, does that mean the PTO can run faster than the drive?


    So the 650 is qualified as a single clutch? I have read about tractors that have a clutch pedal that releases the pto when pushed halfway in and then the drive when pushed in all the way. The 650 isn't one of those?

    According to Hoye:


    There is a lot of confusion about what a Live PTO is and isn't. A live PTO, normally, has a 2 stage clutch. You can depress the clutch 1/2 way in and the transmission will stop but the PTO will continue to spin under a load (not just free spin). If you depress the clutch all the way the PTO will stop also. This is very useful when mowing because you can stop, change gears, back up, etc while the mower continues to receive power.

    If the PTO is not "live" it will stop receiving power every time the clutch pedal is depressed. Because the PTO is always directly connected to the transmission you will need an over run clutch if you use a high momentum implement like a mower.

    Almost none of the Yanmar models have a live PTO. There are those, however, that are making an argument that the PowerShift Yanmar transmission is the sort of the same as a live PTO because you can keep the pto spinning while changing gears and changing directions.

    Some newer tractors have what is called an independent PTO which is usually controlled by an electric switch. You can turn the PTO on and off using the switch and the position of the clutch pedal has no effect on the PTO.
    I thought the 650 does have a two-stage clutch (which if anything doesn't always work as such), so it does in fact have live PTO

    56FordGuy just showed pics of replacing a 650 transmission,,,
    his pics did not show enough parts to allow a 2 stage clutch,,,

    Maybe he will pop in and give his opinion,,,
