Buying Guide

Match spline and shaft specs

Confirm PTO spline count and shaft diameter (e.g., 1-3/8" 6-spline) to ensure correct fit and safe power transfer

Check gear tooth count for starters

Starter compatibility depends on gear teeth and rotation (14- vs 16-tooth, clockwise vs counterclockwise), so match to your engine model

Prioritize material and weld quality

For hooks and spears, look for welded structural steel and corrosion-resistant coatings to endure heavy lifting and outdoor exposure

Confirm vehicle or engine compatibility

Verify listed makes and model ranges (e.g., Briggs & Stratton, Kohler, John Deere) before purchase to avoid returns

Choose keyed sets by coverage needs

Pick a non-duplicated or master key set size based on fleet variety—larger sets cover more OEM equipment patterns
