1486 Draft control lever won't move.Need info

Larry B. 1486 · Jan 19, 2014

Last fall I put the heavy duty 10ft rear blade on my 1486. When I drop the blade, it will not let down slow. It jerks so hard going down, it almost brings the front wheels off the ground with eight weights hanging on the nose. I have owned this tractor for many years, but never used the 3pt for field work. I tried to move the draft lever but it is stuck, won't move. What do I need to do to get this lever to move, so I can move it to slow the hitch arms going down? I'm guessing I will have to squeeze under the cab to get to what needs to be done?

both the position control and draft control levers have a friction adjustment i think it's 7/16" or 1/2" wrench to turn the bolt. if you stand behind the tractor and look up between the cab and right rear wheel, you'll see the 2 linkage rods running fore/aft next to each other.

if it's seized up inside, not sure what you'd do about that.

If it is anything like my 364 there is one shaft inside another and they are sealed on the outside end with o-rings. Probably rusted together and you will need to remove the assembly and use heat and penetrating oil to free it up. I had to do it on mine as it had been sitting for a while when I bought it. Not a big job on mine but I don't know if you have a cab. Make sure you replace the o-rings after you clean everything up and lube it.

Thing is, loosening the draft control lever won't help with the lowering too fast. There is an automatic drop control built into the valve inside, but it is not sensitive enough and this has always been a problem with these hitch's. If you slam the position control very rapidly all the way to the bottom of the slot into the action control offset, it will restrict the drop speed. You have to be quick though and the levers have to be adjusted properly to work. IH came with another method of controlling the drop, but unfortunately to add it to an existing machine without it, you have to take the top cover off and rework the valve and then add a adjusting screw to the inspection plate under the seat. The later 2+2 tractors came with a know on a cable up along side of the seat so an operator didn't have to stand on his head to adjust it. It was also used on some of the 3088 series if I recall correctly.
