Slow dropping 3 point 1256

[dhanraha]

We've got a 1256 with a slow dropping 3 point.  Sometimes it will drop at normal speed, but mostly it takes 3 to 4x as long.  Pulled the pto out this morning and double checked the draft sensing linkage at the torsion bar and above.  All seemed fine.  Where should I look next?  Thanks.

1. Make sure your draft load lever is moving the shaft and not slipping

With a load or empty? First make sure unloading valve is unloading (system not under pressure). Then use position lever to raise hitch part way. Note lever position. Move lever forward until hitch just starts to drop. Measure distance lever moved. Should be 3/8-7/16 inch. More than that needs drop pilot adjustment. If measurement was good. Drop poppet needs cleaning and new oring.

Thanks you guys.  Lever is moving where it hinges on the draft sensing arm.  Arm and torsion shaft do not move.  It is slow to drop with load and without.

I'm sure the lever Kansas was referring to is the control lever in the quadrant. It sounds like your drop poppet is not opening. A heavy load will sometimes push it free.
