Buying Guide

Match shaft and spline specifications

Confirm PTO spline count and shaft diameter (for example 6-spline, 1-3/8") to ensure extenders and couplers fit your tractor driveline

Verify starter model and tooth count

Check the engine or parts manual for starter model numbers and teeth (e.g., 16-tooth) so replacement starters mate with your flywheel and mounting pattern

Prioritize durable materials and machining

Look for hardened steel splines, precision broaching, and corrosion-resistant finishes to extend service life of PTO extenders and keys

Consider keyed sets for fleet maintenance

A non-duplicated heavy equipment key set offers multiple key profiles useful for mixed-brand fleets and reduces downtime swapping unique locks

Use verified fitment info, not just model names

Cross-check part numbers and brand fitment notes (e.g., Kohler, Briggs & Stratton, John Deere compatibility) against your equipment to avoid returns
