B1700 3 point stopped lifting....help!

[Steveinthe603]

Hey all,
I love reading everything here but have not found the answer to my problem....
I have a landpride grader that was attached, while i was using it to grade some rough land in the woods, it just stopped lifting up. I stopped when noticed and tried it again, it tried to lift and then it did nothing. I removed the implement and it doesn't move at all. I looked at the manual and worked my way to the release valve, the spring seems to be fine. It has plenty of hydro fluid and was never low. The PTO front and back turn, the loader works fine too, so i'm sure the pump is ok. The manual states about 10 things that it might be and the relief valve was the only thing i wanted to mess with as this is all new to me.
Any suggestion or help will be appreciated..
Steve

Check the control knob and see if it is shut off. Should be under the seat.

Thanks for the reply , moved the control knob all the way to open and all the way to close but it made no difference either way with the three point lift

check all the linkage to make sure the up-down lever and each following one (if there are more that one) are actually still connected to the next piece in the puzzle of levers and that they are all being actuated thru their full range of motion.

Thanks, all of the levers are working as they look like they should, I never looked that close before it stopped working . I'll look closely and see if it's a possibility...

Usually when these just stop suddenly it's either a hydraulic loss or a lever linkage / feed back linkage issue.
Check the feed back rod connected to the right side lift arm, if it's off that will prevent the lever from getting the three point to move.

Thanks for the advice, I've look at that too and it all seems to be in order

This is what the levers look like
