Cox Mower Height Adjuster Lever
We keep getting asked about this one — the mower height adjuster lever is one of those Cox parts that fails long before the rest of the unit is done. With your sample on the bench this is a realistic reproduction job.

Why these break
Height adjuster levers and caps crack with age. Vibration fatigue does the damage: thousands of small flexes add up to a crack at the stress point, usually right where the part clips or pivots.
How we reproduce them
These take a proper modelling pass: we measure the mounting points and clip geometry from your part, reinforce the known failure point, and verify fit with a test print before the final run.
We print these in Nylon. Nylon is slippery and fatigue-resistant, which makes it the right choice for parts that pivot, slide or flex thousands of times.
As with everything in our library: whether a part can be reproduced depends on size, load, heat, material, and having a decent sample to work from. Send photos first — the assessment costs you nothing, and we'll tell you honestly if a genuine spare is the better option.
