Solution:

Replace Depth Lock Plate. Verify that the replaced Depth Lock Plate has firm contact with the hex
feature of Worm Gear Shaft. Inspect Worm Gear Shaft for wear or “rounding” of the hex feature that
mates with Depth Lock Plate; wear in that area will contribute to the depth control slipping condition
and may require the replacement of worm Gear Shaft.

We suggest that you inspect these areas for wear prior to each season’s use of your Pro Core aerator
to maintain reliable control of the adjusted coring depth.
