    Inexspensive Round Baler

    I just got a New Idea 486 for $2000. I'm pulling it with a JD 2640. Used it for the first time last week to bale first cut orchard grass and alfalfa. All in all worked well. My monitor is just a tie switch and a bale full light. The light stays on even when empty so that needs work. Only made 13...

    JD 2640 and 240 loader

    Hi all I have a 2640 with a 240 quick attach loader. I have been having hydraulic troubles for some time. When the loader is connected to the tractor all the hyd lines get hot, to hot to touch. This usually happens within 30 minutes then I begin to lose power steering. This only happen when the...

    2640 rockshaft stuck in up position

    Thanks for all the help. I did as you said making sure cam follower was in correct position. Then went through the adjustments. The load control adjustment was off by a good bit. Thing are better but not 100%. Did not accomplish "rockshaft control lever neutral range" I think the location...

    2640 rockshaft stuck in up position

    My wife sent me these photos. I'm thinking this is where the negative stop screw will be.

    2640 rockshaft stuck in up position

    Also, when working on the tractor yesterday, I was looking for the negative stop adjustment. It looks like it should be just above the draw bar. But it looks like it might be missing. If all or part of the negative stop adjustment was missing wouldn't the hydraulic fluid drain out? My tractor...

    2640 rockshaft stuck in up position

    Does The cam follower fit between the two halves of the load selector link and roller? Service manual doesn't show that well.

    2640 rockshaft stuck in up position

    I completely removed the ROD screw. Didn't help. Removed the rock shaft housing checked the linkage, everything looks to be as it should, however looking at linkage and moving the selector lever it doesn't look like the linkage is contacting ether valve to activate them. I manually activated the...

    2640 rockshaft stuck in up position

    Went out to bush-hog yesterday. Raised rockshaft, then it would not go down. Control lever feels sloppy like linkage is disconnected. I'm sure I'll have to get in rockshaft housing. I have a service manual, the first thing it says to do is lower rockshaft. Anyone know how that might be...

    JD1020 rockshaft linkage/control lever removal

    Greg, I had the same problem I tried pushing on the plug with my hand and it would not budge. I took a socket and put it over the plug then compressed it with a clamp just enough to get the snap ring off. Socket should be small enough to get to snap ring but large enough not to hit the control...

    2640 Rockshaft inspection and repair

    Thanks Caseboy your reply was timely, accurate and very helpful. I have been praying for a smoking gun with my hydraulic problem. I hope this is it. I had to put a socket on the plug, then using a clamp compressed it enough to get the snap ring out. On one of the valves the o-ring that goes...

    2640 Rockshaft inspection and repair

    I have been following my service manual to diagnose my hydraulic troubles. I have the cylinder and valve housing out. Next step is to inspect the control valves. I can't see how to get the snap ring off. I have a set of fine point picks but can't get under the edge of the snap ring, is there a...

    JD1020 rockshaft linkage/control lever removal

    I'm having the same problem with my 2640 rockshaft. I can't get the snap rings off. Did you find a trick? It looks like no one responded to your question.
