3PH slow to come up

[jsmk]

I noticed soon after buying my CK30HST, after getting a 3ph boom, that it did not come back up as I expected. When I moved the level to the up position it would just sit there then move to selected position at normal speed anywhere from a couple seconds to maybe half a minute.

Things I have tried include:
Changing the speed control all the way slow and all the way fast.
Tried to follow some procedure in the manual for bleeding, I think.
Raising/lowering rpm.

The dealer picked up my tractor to install BH and I mentioned this problem to them. When they installed BH they put AB lever for it. They told me they had noticed no problem with 3ph moving up. I tried it once and it worked okay with the AB level in neutral position.
Well I yesterday I pulled the BH off and put my PHD on. I still have problem with hitch raising. I am sure my dealer will take care of this but may mean having my tractor being gone again. I would really miss the orange in the yard.

Any ideas before I go back to dealer?

I would check the fluid level and the speed knob. Also check the linkage to be sure that the lever is actually moving the valve.

Good points, I made assumption the fluid level was good because tractor is new and dealer just put BH on, but I really shouldn't. I will check that and I never even thought about linkage, so will check that as well. Thanks for the input.

Fluid was down some, but topping it off didn't fix the problem. Checked linkage and all seems right. I am going to do 50hr Monday, I will talk to the dealer tomorrow when I pickup filters. It is possible it is mechanical issue that they will need to deal with anyway. I prefer to solve my own problems when I can.

Is the AB lever in neutral? don't know if it was in A or B if that would stop it from raising, on mine it whines in A or B when nothing is hooked up.

Never tried raising the 3ph while in A or B though, just throwing it out there.

Good Luck

If your dealer is picking it up have them demo it before it leaves the yard to verify the problem and what you've done so far to see if you might have missed anything. Could you say more about what you've done with the 'speed control'; I'm not sure where it is on your CK-20, but it may work similarly to the DK series. If so, it could be hanging up the rise and fall of your 3PH.
There was a recent post about a 3PH NOT coming down and it turned out to be the speed control- search for it, it may help you too.

I had just pulled my BH off to put the PHD on and it would be hard not to remember to move the A/B to neutral with the whine. It has been in neutral during this problem. Thing is I had this problem before they installed the BH and the A/B lever.

I have played with the speed control quite a bit. It sometimes seems like moving it faster or slow triggers the hitch to rise but nothing consistant. I think it would have decided to rise regardless of wether I touched it or not at that moment.

I did find it was easier to remove the PHD with the auger half way in a hole.

The speed control should work where it 'locks' the descent if turned all the way in one direction. It does not affect the upward motion. If you can't get it to work properly have your dealer check it out for you.

The A B detented lever should not be anywhere but neutral UNLESS it has a piece of equipment like a BH that needs to use hydraulics. If it is run withOUT a need for hydraulic fluid one can and will eventually deadhead the hydraulic pump and cause big expensive headaches.
Some do what I did, have a loop hose made up with two male ends to hook into the A B ports on the tractor, which is then installed to allow hydraulic fluid flow in a loop, therefore preventing the possibility of deadheading. It is too easy to put the lever into either A or B accidentally and then not hear it whining while operating the tractor. Ask your dealer to make up a loop for you.

After a closer read of this thread I realized you and not your tractor is going to the dealer. Have you made them aware that you have been having problems with the 3PH prior to the BH install? I suspect the valve which the speed control is connected to is not functioning properly. Whatever the problem bring it to your dealer's attention right away so they can fix it for you. It's under warranty, so don't worry about doing it yourself; that's why you paid for a warranty, right? Not everything is customer solvable.

I didn't understand that the speed control lock only affects down and not up.
I keep the AB in neutral, but agree I should put the loop on. I could see bumping the lever and being so caught up in digging holes or knocking down trees. How long should the loop be?

I did go to the dealer this morning they are going to call me Monday as to next step. They sound like they think it is a valve or something. They have been clear as far as this problem is from day one.

I will mention speed control idea when I talk to them on Monday. I will also get them to make the loop.

Thanks for input.

Glad to be of help. Loop needs to be long enough to go between A and B inputs on back of tractor, probably a couple of feet of hose so it can bend without kinking.
I think your speed control valve is faulty; not the knob, but the valve itself.

What does this mean?: "They have been clear as far as this problem is from day one."

Good luck with outcome of this problem- I'm sure your dealer can fix it for you.

Yeah I thought that might not make sense, but I am typing on an iPad with one finger and it is a pain to edit.
I just meant I have kept the dealer informed about the problem from the beginning.

Is there an access plate that would allow you to see where the speed knob shaft enters the valve which controls the 3PH? If so you could verify if the knob/shaft is actually turning in the valve.

 

[jsmk]

No access panel I could find. The best I could see is a shaft runs directly from the speed knob straight to the top of the case. It seems to be connected and there is no linkage or anything where it might have come loose. I could not see or feel if it was actually turning anything in the case.

 

[jsmk]

I just thought I would give update of the resolution of this problem. The shop expected to bring the tractor in verify a bad valve, return the tractor to me and pick it up again when part came in. Sounded good to me. The delay was all on my side as I really didn't need the 3pt hitch working over the winter, but I did want to low with it. Anyway, they returned the tractor with 3pt working as it should. They said that a small piece of seal, I think like neoprene washer, had been pinched off during assembly and was intermittently blocking valve functioning.
My service center here took care of everything in timely fashion at no expense to me. I am pretty happy with outcome.

I'd like to slow mine down (not as slow as yours was), but don't see any way to do it. When I raise it, it leaps up. It is difficult to control smoothly and I would like better control when I am using the box blade, scraper or the sprayer. I would like it to go up at the same speed as I have adjusted it to go down.

 

[VictorW]

The 3pt lift lever control arm has a zerk fitting to grease the linkage on it's pivot shaft and you can also adjust the tension for the arm. You can see this by looking from the back of the tractor. I have mine (CK30hst) set so it will hold position with vibration but is still reasonably easy to move in small increments.

 

[ERE]

Good info, Victor. Somehow, I never found that zerk so it could definitely use some TLC.
