B7500 3 point hitch hydraulic problem

[dannyk]

Snowman,

The implement lowering limit is a real deal, described with a picture and instructions in my owner's manual. I can check the page number if you like when I get home. It is described on the same page as the operation of the hydraulic lift lever in the Tractor Operation section. My tractor was delivered in 2003, so I can't say whether yours has it or not.

The limiter is on the feedback rod, but changing its position on the rod or rotating it does not in any way change the position or the functioning of the rod, except of course that when you slide it towards the rear of the tractor along the rod it limits the downward travel of the three point arms. I assume that the mechanism works just like the spring and lock nuts on the rear of the feedback rod. The spring and nuts on the rear of the rod limit the UPWARD travel of the lift arms.

I am definitely not talking about the knob below the FRONT of the seat which controls the rate of downward movement of an implement on the 3 point. This knob would be, in my view, an extremely cumbersome way of trying to adjust the height of the arms. The limiter on the feedback rod does this automatically and without problems when mowing.

Ok..I understand now - the upward movement is what you're limiting. You're right, the knob only limits the down movement.

I'm pretty sure that I don't have this on mine, as I read my manual ("leaflet with crude pictures" actually) thoroughly and don't recall this.

Thanks.

Snowman,

The limiter that has been giving me headaches is on the forward end of the rod and limits the DOWNWARD travel of the lift arms to the extent that it is moved backwards along the rod. However, on the rear end of the rod there are two locknuts and a spring which limit the UPWARD travel of the arms.

I should mention that my comment about Kubota not expecting anyone to actually use the limiter was tongue in cheek. I know, I have a wierd sense of humor. /forums/images/graemlins/tongue.gif

By the way, I first started experimenting with the limiter a year ago when I was inquiring about using check chains with the brush hog. One TBN member was supporting their use, but someone else with a B7500 asked me why I didn't simply use the limiter on the feedback rod.
