Can the 3pt hold a position?

[millerized]

BX22, bush hog on the back. 3 point goes up, but won't hold that 'up' position. Is it the adjustment on the end? Did I finally dick something up? Knob under the seat slows it down, but it doesn't stop it. Only way to hold position is to hold the lever in the up position.
Anything I'm missing?

 

[MadMax31]

My B7610 will hold for a long time. It may bleed down overnight.

What size cutter are you using? If your using a 5' hog at almost 600lbs then your 3pt cant handle it anyway...

I re-read, mine lifts or lowers by moving knob, return knob to middle to maintain a spot. Yours may have "Quarter Inching" which you may need to keep knob at raised position?

 

[millerized]

4' Countryline, 345lbs.
The FEL and BH would drop overnight, but not while watching it in under 30 seconds.

 

[MadMax31]

The simplest way to guess... My 3pt control has up and down arrows with a "neutral" middle. If I forget that my 3pt control is set for lift, my loader acts funny. Return the 3pt to middle and all is well.

Im guessing if yours has numbers, 1-9? That you can leave it at lift and your loader will act normal?

If I raise my hog, and return my knob to middle, it wont drop until I push lever towards lower. If I lower the hog, it wont move even if I return the knob to the middle. Pretty crappy but its better than not having any 3pt control. The L3301 and Deere 3038e both have the quarter inching control which is way better than mine. Just move lever to desired number and hitch drops to the same spot every time.

Have you checked the fluid level or checked for any leaks? Could also have air in system

Simple answer is if you don't have position control 3PH, it will leak down, no BX has position control, we have two.

This is commonly asked question.

Could you clarify the 'position control' and 'we have two' part please?
I was raised on a Massey Ferguson TO-20. Wherever you left the lever position wise, the 3pt stayed in that position until you told it to do otherwise. That's why this is a puzzle to me.
There are positioning stops on the rod that connects to the lever. Springs between them and the mount on the body. Are those what you are talking about with the 'we have two'?

"We have two" BXs. We also had a JD2305, same system, but our JD1025R has "position control".

About half way through, he explains "position control" 3PH. https://www.youtube.com/watch?v=TX5J5suE-Gs

Makes sense now
Will give it a peek.
Thanks for the response.
Let everyone know what I find out.
Hopefully it's something simple and I'm just a clueless idiot (I'm good with that cause I'm used to it!)

Again, thanks!

Well, nothing mentioned worked. Took enough off to get to the guts of the adjustment knob. Bright, shiny and perfect inside. That didn't do anything for a fix, it just let me know that 'it' isn't one of the things causing the problem.

Currently walking myself through the parts lists to get all the soft parts for a repair on both the control valve and the hydraulic cylinder. That'll be a fix for next month. Doesn't look all that hard to accomplish, just a lot of crap to take off to get to it. I got most of it off and back on in 5hrs yesterday, so I figure a weekend will give me the time I need once parts are in. Helps having the right tools.

Right now, I've got the bush hog chained in a level position to make sure it works and will cut without any incidents. All I'm really doing is supporting the arms, so it shouldn't be a big deal. I'll swap out chain and hooks I'm using now for chain and turnbuckles for next weekend. That way if I need any adjustment, I'll have about 4-5" worth. (more if I shorten/lengthen the chain) I've got full up/down to get it into place....I think it'll work out just fine.

I'll be towing the 'whole' package to PA, using it at the farm for the long weekend coming up, unhook the FEL and BH, then bringing just the tractor back to work on. Once repairs are completed, I'll take it back home and leave it.

Non position control tractors is why they make check chains, lots of people use them on the BX and older B Models. I just "bump" mine up occasionally.

I can't bump that fast/much. Even at full 'close' on the adjustment knob, it drops to ground level in less than 20 seconds. Not something I want to do while mowing....that'd look like he77.
Good to know I'm not the first to use chains. Just need to do them right so I don't damage bodywork or implement, while still getting some adjustment if necessary.

 

[MadMax31]

So you lift 3pt all the way, close the valve, and it still bleeds down? I would guess the piston seals that drive the rockshaft are worn or worse.

I didn't realize it was dropping that fast, definitely excessive and in need of addressing.

Yup...already ordered. 5-7days from the 'warehouse'. Replacing all the guts (soft ones, O-rings/seals) in the control/valve assembly as well. Might as well kill both stones with one bird.

And the kicker is that the 3pt has never been 'used' for an implement until I tried hooking up the bush hog. The tractor was new when my dad bought it in 2002/3, all of the 3pt hardware was still in the wrappers when I got it in 2011ish and unattached to the trailer until last week. The BH and the FEL have been on it since he bought it, only taken off long enough to do the normal maintenance on it in the garage. Outside of up/down playing with the levers, it'd never lifted a load until last week as well.
Guess it was about time something 'major' happened to it. Luckily, I've spent all my drinking money of the last 20yrs on tools, and the gray cells I have left are well versed in 'fixin' stuff.
We'll get it fixed...I have a plan


At least I don't have to split the case to get to it...I HATE splitting cases.

Money spent on tools is money well spent. My brother has been buying them for fifty years since I showed him how to change the transmission on my old 54 Ford. My skills never improved much beyond that, but he made a good living and keeps all of our machinery going. Splitting a tractor to me is like brain surgery, but he's done a few.

miller,, "never been used"... There's your problem. Seal staying in one spot on iron sticks to the metal. First time it's moved after a long sit, it tears or pulls little chunks out of the seal. Polish that cylinder real good when you get the piston out of it.

Figured that was the case with it. Just sat too long. At least it won't set that way again.

It's a shame since dad built a really nice PTO driven 3pt attached log splitter that would have gotten a work-out had he not gotten sick. Even the apple grinder and cider press are 3pt/PTO powered items...things that should all be back in use once we get this fixed. Guess I'm doing it for dad as much as myself.

It's just time spent, bit of effort and $40 in O-rings and 'stuff' for the whole rebuild. Since I love working on things like this, it's no big deal. Might even learn something from it.

Holy crap that was fast. Ordered parts from Messick's the evening of the 15th...parts are shipping as we speak. Depending on speed, I could receive them tomorrow (I'm only 2hrs from there) or early next week.

I might not even need the chains if I could get to the work this coming week. If it weren't for 13+hr days...I'd have it done in less than 2 days....but....that schedule doesn't end for another month+.

Chains for a 10ac mowing job, then a repair. Gonna be a good few weeks.

 

[millerized]

Finally got off my butt and fixed it. Damn sure have to take the whole rear apart, don't ya?!!!
16hrs start to finish. Cleaned out all the hay from the last cutting, got a few things ready for the new season while I was at it.
I didn't remove the side frames completely...just moved them out a bit to get the cross member and upper support off the 3pt cylinder housing. Reallll beeotch and lots of big rusted bolts to contend with.
Anyway...in no particular order....
