The owner walks through matching dimensions to his L3901's lift arm, fixing a mismatched pin hole with brass bushings, painting it, and marking stripes for setting level from the seat. Useful for owners frustrated with manual link adjustment who want a DIY-verified parts-fit solution.
An owner-operator sharing a detailed hands-on modification and fitting process from personal experience with his own Kubota.

The knuckle hole measured seven eighths inch instead of the stated thirteen sixteenths. He fit two brass bushings, with 7/8 inch OD and 3/4 inch ID, pressed together with a vise.
A painted orange stripe marks the level length. When it comes into view, the top of the stripe aligns with the bottom of the protective shroud, indicating level.
