Is there a safety switch on the three point hitch?
My front bucket works great but the 3 point doesn't raise and lower any more.
I'm still waiting on delivery of my service manual which should explain it but I'm too impatient
There is no "safety switch" or interlock as far as I know.
There is a..... Hmmm, how to describe it ????
Lets call it an "extra input" to the position control.
It is on the left side of the rear axle and (the way I look at it) it is intended to take a control cable - looks as if a bicycle brake cable would fit.
There is reference in the shop manual to using it for a rear implement, the translation is confusing, but I take it to mean that a control cable from a roto-tiller can be used as a third input to the 3 ph hydraulic control. The first 2 being the lever and the rock shaft's actual position.
(Maybe it is the 4th input, draft control being the third)
Anyway, if you can find that it might be worth CAREFULLY moving it to see if you can get it to raise/lower the 3 ph.
Just getting in there and looking at it and the other two inputs might reveal something amiss.
Say a twig jammed up in the little levers and mechanisms.
Let me know if you need pics, I can probably shoot some today, or maybe scan a page from the manual that describes this if the snow and rain gets bad.
EDIT:
I just looked outside and remembered that my hoe is on right now.
It might be tricky trying to get pics and the lift arms are fully raised and have to stay that way.
I'll dig out the manual.
