Buying Guide

Confirm model and spline/specs

Match PTO spline size, starter gear teeth, or engine model to your equipment to ensure fit and safe operation

Prioritize OEM vs compatible parts

Choose genuine OEM kits when ease of fit and manufacturer maintenance specs matter, and quality compatibles for lower-cost repairs

Check material and build

Look for hardened splines, welded tines, and corrosion-resistant finishes on shafts and attachments to extend service life

Consider power and torque ratings

Verify horsepower or torque compatibility for PTO extenders and shafts to avoid overstressing driveline components

Assess included components

Prefer starter and maintenance kits that include necessary gaskets, filters, or mounting hardware to simplify installation

Plan for safety and mounting

Confirm secure locking mechanisms, shield compatibility, and correct mounting points for implements like hay spears and bale forks
