Have a single 16 Oliver w/ rooster comb lift. Plows great, but getting it out of the ground by tripping it is the problem. I trip the plow while in the ground and the rooster drops and cannot complete the full cycle (ride up rollers 1/2 way then the rooster hops out, cycle repeats 1/2 way then rooster hops out, on and on).

Looking for ideas on what to look at next.

Replaced lift spring on rod w/ new spring. Replaced 1 1/2 turn spring under lift pawl.
Made sure rooter and rollers are aligned.
Eveything moves freely and is greased.
Adjusted hitch on tractor high and low.
Played w/ levelling lever, no change.
While in ground, stopped, pulled rooster all the way up, no change.
With 1 person having 1 foot on rooster comb (keeping it in thee rollers), plow will pick itself up).

Help, want to use this on 4/17, but I can not trust it.

I"ve attached a picture of the lift mechanism from my plow (before it was restored). There is a roller (some models had 2 rollers) in the Lift Frame for the "Power Lift Bar" (notched rectangular bar that runs to the axil) to run on. I recommend that you check the roller(s) over (and under) this lift bar. This area gets full of dried grease, oil and dirt. The lower roller on mine had been stuck for so long that the roller had a flat spot worn from the lift bar sliding over it. Clean the lift frame, make sure the rollers turn freely. You might also want to check the pivot point where the power lift bar attaches to the axil.
Hope this helps.

Good luck,
