I have a 2007 Foton 254 with Koyker 140 loader.
I am just putting this out there for others like myself.
While bush hogging in some honeysuckle my tractor started lugging bad. I assumed I had wrapped vines around my blades and was choking it down. So, I pulled out and shut down the PTO. NOT IT.
HUM. Tractor will not rev and when I try to lower front bucket it goes up. What is going on??? I limp back to the house about 50 yards away. I had just fueled up about 30 minutes prior from a jug. I thought I had bad fuel or water. I put a new fuel filter on and no change. At this point I am thinking, great now I need an injector pump.
One thing that was puzzleing me was that at the same time my hydros go crazy. Wierd things have happened to hyros with low RPMs before. I shrug it off, think to myself, get it running right first. I spent roughly 4 hours checking everything I could possibly think of. NO LUCK
Google is your friend, I think... My googlefu is weak to start with. BUT I did find one brief mention of a John Deere that would not rev for a jammed hydro lever. That gets me to thinking they are related. I start trying to chase a leak, low fluid, broken line, basicly anything. NOTHING.
I decided to goto the dealer and have a mechanic come look. He was busy but started asking what was going on. I told him and he says oh that's simple.
Under the tractor (below the break pedals) is a quick connector for the FEL hydros. It faces forward, easy for a vine to unhook. Even though it does not look disconnected it was. PROBLEM SOLVED
My tractor runs with an open center system and so does the FEL. With the one side open there was apparently no flow. Lucky I did not have to many horses or probably would have shrapnelized a hydro pump.
Just a little help for the next person scratching thier head when their tractor won't rev up and the hydros go crazy.
