Has anyone ever had a problem with the governor not wanting to return to idle intermittently ? I am trying to get my old tractor ready to pull in some antique pulls with a 20% over stock RPM limit. This tractor has been sitting for 8 years without being ran, I rebuilt the engine got it running good and went to work on the governor. When I bought the tractor 15 years ago the gov spring was wired really short and the tractor would turn a butt load of RPMsm back then there wasn't a limit in the pulls that I pulled in so I was happy that it turned so many RPMs but now I need to turn only 1920 and I can get that in the first 1/4" of throttle. So I pulled the spring out got rid of the wire that was holding it together, and put it back together, now when I rev it only goes to 1900, so that is close enough but sometimes it would not return to idle, I have been messing with it all day and it seems like the weights or something are sticking. I got the idle set at roughly 400 RPMs. Sometimes I can rev it up but when I pull back on the throttle it only goes down to 1000 RPMs. I have the cover off of the governor and I can see that the spring is putting no tension on the on the arm when I pull all the way back on the throttle, and it still will not return idle without me pushing back on the arm on the govern side of the spring (not the side attached to the throttle linkage). If I adjust the linkage until the spring pushes back on the arm when at idle then it will idle but then I can only get about 1500 rpms and it doesn't seem like the spring would need to push it back to idle but only not pull against it and the weights woulld return it to idle.I can completely unhook the spring and it will still not go to idle sometimes, it seems that without the spring to pull again the weights that the tractor would idle all the idle all the time but mine wants to run 1000 rpms most of the time.[/list]

Today's Featured Article - Hydraulics - Cylinder Anatomy - by Curtis von Fange. Let’s make one more addition to our series on hydraulics. I’ve noticed a few questions in the comment section that could pertain to hydraulic cylinders so I thought we could take a short look at this real workhorse of the circuit. Cylinders are the reason for the hydraulic circuit. They take the fluid power delivered from the pump and magically change it into mechanical power. There are many types of cylinders that one might run across on a farm scenario. Each one could take a chapter in
