Positions to Recheck after Replacing Reversible Plough Parts

Replacing a worn share, a bent pin or a leaky ram is only half the job. The reassembled plough must be checked again, because even a good part fitted into a slightly disturbed setting leaves the machine working off-balance. A short recheck routine after every major part change prevents the repair from becoming the next problem.

Check the frame sits level

After removing and refitting body brackets or link pins, the frame may have settled slightly. Lower the plough on flat ground and check that the frame sits level side to side and front to back. A small tilt here changes depth across the width of the plough. Correct the levelling adjustment before going back to work.

Verify body angles match

Compare every body against its neighbours. A newly fitted body bracket or a replaced frog can leave one body at a slightly different angle. Bodies that cut at matching angles turn evenly; one outlier creates a ridge in the furrow. Sight along the bodies and compare share points from one end of the beam to the other.

Re-test depth and furrow width

Run a short trial pass and measure the actual furrow depth and width. After a part change, the plough may run slightly deeper or shallower than before. Adjust the depth wheel and top link until the cut matches the intended setting. Relying on memory of the old setting often leaves the plough working at the wrong depth.

Check the reversal mechanism

If the work involved the ram, pivot pins or reversal frame, cycle the flip several times. The frame should rotate fully in both directions and hold its position without drift. A pin replaced after wear should feel tight in its bracket. Any stiffness or slowness here is corrected now, not discovered at the next headland.

Mark the settings for next time

Once the recheck is complete, mark the adjustment positions with paint or a small note. Next time a similar part is changed, the setup point is already known. A well-recorded plough returns to correct settings in minutes, and the field finish stays consistent season after season.
