Bad spool valve ? tractor does not move. Low fluid, plugged fIlter ? lift cylinder works but tractor will not move. Bad shift linkage! Internal oil leak in valve? looking for help figuring out my tractor weird behavoir to go forward up a 15 degree incline I have to find a sweet spot with the directional handle. Too far it won't climb and irs not a lack of power. On level ground it works ok. thank you 1 Share this post Link to post Share on other sites

But the acceleration valve is a common component on all hydro units. Edited June 22, 2019 by bcgold Share this post Link to post Share on other sites
