bmk Posted May 1, 2021 Share Posted May 1, 2021 When we use the remotes on the 1256, you have to be very easy and move the lever very little to let anything hooked to it down or it will lock the cylinder. Only way to unlock it is to raise it back just a little and try to go down again. My help said something about it last year with the rake, and I forgot about it till I hooked the disk to it yesterday. I tried the other remote and its the same way. Is something out of adjustment in the valve? No problems raising up. This is the only tractor we got that does this. Link to comment Share on other sites More sharing options...
Nebraska1206 Posted May 1, 2021 Share Posted May 1, 2021 Do you have the factory check blocks on the hydraulic remote outlets of your 1256? Basically it's the block that I have circled here. It's a check valve to keep the remotes from seeping by & allowing the hydraulics on a implement to settle. They can have a way of making operation of hydraulic cylinders on equipment rather jerky. We removed them from my good 1256 because they interfered with the raising and lowering of our corn planter. Link to comment Share on other sites More sharing options...
junkandcattle Posted May 1, 2021 Share Posted May 1, 2021 Weak hydraulic couplers can cause similar problems also Link to comment Share on other sites More sharing options...

I thank its setup just like this, Ill look tomorrow to make sure. Lines come down and have couplings, not like the couplings on the right side of your picture.

snoshoe Posted May 1, 2021 Share Posted May 1, 2021 Try replacing female couplers on tractor. Link to comment Share on other sites More sharing options...
bmk Posted May 2, 2021 Author Share Posted May 2, 2021 My blocks looks just like what you have circled with the lines going from the block back up under the seat, on both sides. I can take the one on the right loose from the lines, but the one on the left has the lines made directly in the back. Can i take the check valve out of the block or will it have to be completely changed? Link to comment Share on other sites More sharing options...
snoshoe Posted May 2, 2021 Share Posted May 2, 2021 The check valve keeps it from settling. I'm 90 percent sure your problem is the couplers checking. The double acting checks bother with planters and drills with markers. For those applications there is an alternating check valve. Link to comment Share on other sites More sharing options...
bmk Posted May 2, 2021 Author Share Posted May 2, 2021 Thanks for the replies. We will change the couplers and go from there. Link to comment Share on other sites More sharing options...
ksfarmdude Posted May 2, 2021 Share Posted May 2, 2021 Get rid of the check valve blocks completely all they do is restrict oil flow I took them all off my 656 you won't miss them Link to comment Share on other sites More sharing options...
bmk Posted May 9, 2021 Author Share Posted May 9, 2021 I changed the female couplers on the left side, it solved my problem. Will get a set for the other side when i get a chance. Thanks for the help. Link to comment Share on other sites More sharing options...
885 Posted May 11, 2021 Share Posted May 11, 2021 I took the block off my 706 as it was causing problems with the corn planter. Would raise smooth but bounce down, now it's smooth up and down Link to comment Share on other sites More sharing options...
