shorts 182 #2 Posted May 6, 2011 check the linkage adjustment, these hydrostats should work equally well in both directions if they work in 1 direction Share this post Link to post Share on other sites

rexman72 210 #4 Posted May 7, 2011 check the linkage adjustment, these hydrostats should work equally well in both directions if they work in 1 direction ok i adjusted the cam plate so the tractor goes alittle faster but the cam still can move forward alittle more to make it go faster and i cant figure it out how to get it to the end.any ideas because if i get it to the end of the forward plate that tractor ill take off.thanks Share this post Link to post Share on other sites
smoreau 658 #5 Posted May 7, 2011 Sounds like part of the linkage is warn not allowing it to move the control in the pump far enough. Share this post Link to post Share on other sites
rexman72 210 #6 Posted May 7, 2011 ok i adjusted the bolt on the cam and the tractor seems to go faster in forward but the cam doesnt want to move all the way forward to move the fastest it goes.it seems like the rod going from the motion lever to the cam may be to long.does anyone know if you can adjust the rod so it will go to the end of the cam or any other ideas would be great.thanks.

SAM58 30 #7 Posted May 7, 2011 :thumbs: See if you can find a service manual for it, there should be complete instructions for adjusting the linkage... I have seen the linkage loose under the center consol plate. Also the rod has threads so you can shorten, or lengthen. Probally has several hours on it.. Not hard to do. :D Share this post Link to post Share on other sites
illinilefttackle 399 #8 Posted May 7, 2011 The cam plate has slots in it that wear-and don't push the control levers on the pump far enough-get a new plate and you are good to go-Al Share this post Link to post Share on other sites
Forest Road 594 #9 Posted May 8, 2011 Pull the covers off so you can see all of the linkage. Somehting may have dropped in there preventing you from moving to full forward. I had a 520 w/ a bolt stuck in the linkage somehow. It costs the PO quite a bit at point of sale. Go me!!! Share this post Link to post Share on other sites
rexman72 210 #10 Posted May 8, 2011 The cam plate has slots in it that wear-and don't push the control levers on the pump far enough-get a new plate and you are good to go-Al i took the fender and consol off and adjusted the rod going from the motion lever to the cam plate and now the tractor is running the way it should be.I did order a cam plate because the existing plate is worn.This tractor is new to me and i thankyou guys for helping me out.i have many other questions that i will be asking about it later.this site has so many good people with alot of knowledge.thanks again.
