With genuine depth adjustment parts being very expensive we have developed new components which are better than the original when it comes to composition, durability, operation and price.

Our new Depth adjustment axle (prototype), depth adjustment arm (AA108R & AA109L ) and ‘T’ Handles (AA710) are no exception!

I’m sure you have all had seized gauge wheel arms and been unable to adjust your depth at some point. We have tried hard over the last three years to come up with a solution and our new prototype is the turning point in eliminating these jammed axles.

Our new gauge wheel depth adjustment axle will replace the following parts – A, B, D, J & T, (on the parts reference available in the Members area)


Normally part N is also replaced but with our new system your damaged/worn depth adjustment arm can be re-used, saving even more.
