No...still working on it. I thought everybody had given up on my problem. I mowed (bush-hogged) with it Friday. I used it in manual throttle and cruise control. As long as cruise control is all the way forward...no problem. When you pull the cruise control back, the problem is there. But, when I finished mowing I put it in auto throttle, I pushed the pedal in reverse, it throttled up normally and started backwards. Then the pedal felt like it broke over center and it went to idle. Then I had to manually put it back to the neutral pedal position. Then I pushed the pedal down to go forward, and the same thing happened. It throttled, moved forward, broke over center, went to idle with the pedal down in the forward position. To get it home, I took it out of auto throttle, used the manual throttle and pushed the pedal slightly to get it home. I figured it had finally broke, and I would at least find out what the problem was. After it cooled off, I started it, drove it, it was fine. Only happens after the tractor is used for awhile. I really appreciate you asking if I had it fixed. Hopefully someone will read this and have an answer!

Thank you very much! I will check on this in the next few days. Also, I ordered the shop and the parts manuals this morning.

Bringing this back up because I am having the same issue. I can kill my tractor and recrank it and it will go to around 2800 rpm. As soon as I use any function on the tractor it drops to around 2200 rpm. If I back the tractor up 2800 rpm again.

I figured someone would have chimed in by now. Anyhow, after a complete diesel empty, clean, filter my tractor got her groove back.:D

Opening this one back up.

I have been checking on line to try and see if someone was having the same issue as me when I came across this site so I signed up. I am having the same issues with my L3240 rpm up and down. I read all the replies and tried them all with no luck, did you ever figure out the issue?
