I was aerating last friday and went to adjust the rate of drop and the knob is stuck. It wont turn in either direction. I looked from the back of the tractor where the knob connects to the shaft and the only thing I can see is a small bolt that screws into the side of the shaft, does that need to be loosened some or is it there to apply pressure so the knob and shaft that runs inside of it dont fall out?

I'm not sure of the problem but I do know the knob can be really hard to turn under pressure.

Do you use the knob often or has it been a while since you tried to turn it? It is one of those controls that has a tendency to get hard to turn if not used frequently (or if not kept lubricated). Try spraying some penetrating oil down into the area where the shaft enters the rockshaft housing. After soaking try gently turning it back and forth. You do NOT want to break it off in the case.

I have never found the knob to be hard to turn under pressure. I constantly adjust it with my 800 lb. ballast box attached and it turns just as easy as when there is nothing on the 3PH.

Interesting. I don't ever remember having an issue with mine under pressure but the other day I went to make an adjustment and the knob was really hard to turn, I dropped the hitch and the adjustment was very easy.
I have not had to make an adjustment for like three years so maybe lack of use could have played a part in it.

Ive only had the tractor a month and tried to adjust it the first time last friday. I tried to turn it with the lift in the up position and in the down position with the same results. Was hoping it would be something simple but if not, the dealer will have to be involved.

Thanks for the breakdown Giz, looks like that bolt is supposed to be tight since it has a nut on the back. I wont mess with it.

When I adjusted my hydraulic pressure the other day I had to remove the panel trim under the rate of drop knob and it seemed like it was froze up. I had to lube it and work it back and forth and finally it freed up. I hadn't touched it since I purchased the tractor in 2017. I have to remind myself to hit that with some lubricant when greasing the loader.

With my 2305 and my 2025, if the knob was fully closed position and I started the tractor, there was no way in hell I could turn it. I would have to shut the tractor off, work the SCV and leave it in "float", and after a while, I could turn it. If I know I'm going to use the control, I will crack it open about a 1/4 turn before starting the tractor.
