    640 loader issue

    After doing my pressure testing I ran the tractor for a while with a brush mower (FEL still attached). After about 2 hrs of use I used the loader to move a few piles of mulch and noticed a change. I was still unable to lift the front of the tractor off the ground but it was working a bit...

    640 loader issue

    I made up a gauge and plugged it into the quick connect couplers on the side. I'm reading about 1200 for both directions of the boom and about 1100 for the bucket functions. I'm guessing I'll be pulling both boom cylinders off again to open them up and see what went wrong with the assembly.

    640 loader issue

    I swapped out the bucket and boom circuits and I'm still not able to lift the tractor using the loader. So... that brings me back to the loader itself, which on one hand is easier because it's more straight forward, however I'll have to reopen both cylinders and check the seals. I re-sealed one...

    640 loader issue

    I have a JD 6410 with a 640 loader and have lost power on the raise/lower function. It will raise slowly if empty, but won't lift anything. The curl function works fine, I can raise the tractor off the ground with the bucket. I thought I may have a bad boom cylinder so I rebuilt both of them. I...

    6410 reverser/starting issue

    Problem solved! After extensive circuit testing, fuse & solenoid tests (replacements) I couldn't find anything wrong. I kept going back to the neutral start switch and how it would start when jumped, but not when plugged into sensor. The sensor was BRAND NEW so I never doubted it. I decided to...

    6410 reverser/starting issue

    Alright.... I know more, but still don't have a moving tractor. I swapped the electronic reverser switch out with one that was known to be good, and I still have the same issue. I checked relays K210-K213 with a known working one (new), and in the end just replaced relays K212 and K213 with...

    6410 reverser/starting issue

    Thanks, I'll look into the lever itself. Another user posted something about a bad ground wire; so, I plan on chasing some wires back as well. I can hear the relays clicking when I move the reverser lever forward or backwards, would that be happening if the lever itself isn't working correctly...

    6410 reverser/starting issue

    So I'm thinking this is now more of an electrical/sensor/relay issue than a mechanical one, although I did have a mechanical issue with the broken spring. If I put a jumper into the Neutral start switch harness the tractor will start right up. Once its running, if I put it in gear and try to...

    6410 reverser/starting issue

    The mystery continues... Had a Deere service Tech come out and look at the machine. We narrowed it down to a problem with the reversing valve. I pulled the bottom plate off and found that a spring had broken and got stuck in the valve causing it to be stuck open. This prevented it from starting...

    6410 reverser/starting issue

    Having an issue with my 6410. The problem began with the reverser not working correctly, it would only go into reverse and when I put it to forward it also would beep and go in reverse. I shut it down and now nothing happens when I turn the key to start it. It appears that it thinks it's not...

    JD 6410 how do you remove this?

    I took the 8 bolts out, and removed the snap ring. But it doesn't budge and don't want to force anything I'm not supposed to. Pic to follow

    What is this?

    I have a '99 6410. This sensor is located on the top of the head near the firewall on the drivers side. It has one wire coming out of it that isn't connected to anything. The first picture uploaded sideway's for some reason...gotta turn your head to the left.

    6410 Hydraulic temp light coming on

    I'm having an issue with my 6410 that perhaps someone could help with? I recently had to change the pump located inside the front of the transmission. I noticed the shaft was cracked (on the outside, no damage inside) while changing out the u-joints on the short driveshaft from the engine. I...
