3-Point Hitch BX25 3 point lowering question

[paulemar]

I have the Kubota ballast box for my BX25 and it won't lower enough to sit on the ground for removal. I have to put 4 X 4's or cement blocks under it to set it down. I also spent a short time trying to get my Brinly cat 0 3 point one bottom plow set up and couldn't get it to go deep enough. It appears that the lift arms don't go down far enough. I've adjusted the top link every which way but ran out of daylight before finding an answer. I don't believe that there are any additional holes in the lift arms to make the adjustment. I've heard of folks having a problem with the 3 point not lifting high enough, but not this, and I've had no luck thus far finding anything by a search. Any ideas on what to try when I get back this weekend?

Do you have any pictures of the rear set-up with the implement lowered?....Or even one with implement off and the arms lowered?

Seems to me that the upper arms don't have full down travel..Trying to think of causes for that.

I'll get a picture as soon as I can. Here's some more info that I thought of that might be helpful. This is the first time the 3 pt hitch has been installed since I removed the backhoe last week. It works except for not enough down travel. It was mostly put together by the dealer when I got it with the tractor last February. The ballast box was just put on, empty. One thing I noticed when I checked everything out soon after getting the tractor was that the hydraulic fluid was really, really full to the point where some came out under slight pressure when I removed the dipstick. At the time, I just put the dipstick back quickly. Could there not be any more room for fluid when the lift arms descend to the point where they stop and they are under pressure? Tomorrow (Saturday) I'll try a few things like adding some weight to the ballast box and maybe lowering the 3pt hitch with the hydraulic fluid dipstick removed. (good idea or not)
I just now looked in my manual and the hydraulic fluid was overfilled when I previously checked because it was definitely above the top line on the dipstick to the point of overflowing. When I did my 50 hour service, I lost, at most, a couple of ounces of fluid, so it could still be overfilled. Would a hydraulic reservoir that is seriously overfilled prevent the lift arms from descending all the way?
Thanks, Paul

Check/twist the knob that determines the speed of drop under your legs. Free advise which may be worth nothing.

There should be a space in the reservoir for expansion.

It sounds like you are way over filled. If there is no place for incoming fluid, that might be a problem, and might blow some seals.

Whatever attachment you have installed, after cycling the unit several times, the cyl's should be full and then you should have a space for heat expansion.

Your dipstick should have a mark for proper fill level.

With nothing on the 3pt arms, how far down does it go?

Are your side links tighten to much?

The top link might not be the correct one for a certain attachment.

If the 3pt lowers at a speed to your satisfaction, then the knob has nothing to do with how far the lift arms fall.

The knob adjust the drop speed and will lock the 3pt in a certain position.

Have you adjusted your mower height knob to 0

Is the mowing deck still on? Since you just removed the backhoe I would also try disconnecting and reconnecting the hydraulic bypass hose for the backhoe in case it didn't seat tight when you plugged it in. Mine is a pretty tight fit and takes some fiddling to get it to snap in.

OK, I believe I'm a contender for TBN idiot of the month, I got home from work, ran out to the tractor expecting to find an overflowing hydraulic fluid level. Nope! I couldn't even see any fluid. DUH! Then I realized that I just put the new hydraulic 60" snow blade that I bought a few weeks ago on the front of the tractor . That's why I was putting the 3 point ballast box on to help with traction and as a counter weight to the snow blade. It never dawned on me that there were 2 hydraulic cylinders and 4 hoses that were likely empty and would fill with fluid. I even allowed for that when I installed the blade by running the engine for around 5 minutes at low idle to fill the system.

Anyway, I added around 2 1/2 quarts of SUDT2 to bring fluid level up to a little bit higher than it should be. I'll move the tractor to a more level spot tomorrow, warm it up, and fine tune the fluid level. Then I'll check the 3 point hitch. I'll bet it works like it should. I'll let everyone know what happens.

I'm guessing it will still be shy. I had the same problem with my BX25 ballast box and with 3pt forks. My solution was to purchase another adjustable side link. It comes with one to balance the lifting arms but with two you can adjust both arms down to a proper height. I think it was about $15.

My box blade barely touches the ground and the same for my scraper blade. I bought a quick hitch and my solution was to drill a couple of extra holes in the qh to make the implement go lower.
