Sluggish 716H hydro tranny

I'm wondering if the two dump valves (two buttons on the top of the tranny) are partially stuck open. With the engine at a high idle or fast speed, moving the hydro stick quickly forward makes the tractor accelerates fairly slowly. If any of you guys could measure how far up the buttons stick through their bolts, I'd appreciate it. If mine are stuck a bit, is it just a matter of unscrewing them and cleaning them out? I have tools for the 12point transmission bolts.[A href='http://www.wheatfarm.com']http://www.wheatfarm.com[/a]

Hi. I also had trouble with a sluggish hydro on my Sovereign. Found that lubricating all of the linkages, and removing the roller cam, and lubricating the inside of the roller with grease made a large difference. As far as the extra springs are concerned....they should not be there. You should be able to adjust your neutral without them, and it should stay. My 2cents worth...or so. GordU

Check the "soft ride" spring in the control linkage. It is right in front of u with the seat deck back. We ALWAYS cut a roll pin or keystock & zip tie it around this spring to negate it'e effect. As things get gummy/dirty it allows the control to move without moving the hydro shaft causing a problem like yours & also running away on a downhill. Bill

I've noticed that reverse is rather snappy compared to moving forward. I'll play with locking out the spring, or maybe getting a spring a couple of steps stiffer. Thanks for the input. Another thing. A previous owner added a pair of springs at the top and bottom of the cam plate that goes into the hydro to stop the tractor from creaping in neutral. How exactly are those springs doing that? Is there a piece I can replace to restore operation to normal without needing the springs? They are plainly visible in this picture.

Hi, Lubrication is the answer. The bottom spring is stock. There is a post a while back about adjusting and servicing this linkage and neutral adjust. Good luck, Al E

I stuck a piece of 1/4 copper tubing alongside the spring and tie-wrapped it in place today. Bill is right, it prevents run away when turning down hill. Question, it seems like my hydro control level is getting stiff at the pivot point. What's the best way to lubricate it? Thanks, Roy
