Adjusting Tire Scraper

IMPORTANT: Load and tire air pressure will affect distance between tire and scraper. Tire diameter will change as tire warms up during transport. Do not set scraper closer than the specification.

IMPORTANT: To prevent damage to row unit coulter or contact drive tire, tire scraper must be re-adjusted anytime frame height is changed.

1. Adjust tire to correct air pressure.

IMPORTANT: When adjusting scraper, ensure that it does not hit coulter on row unit behind tire.
