Buying Guide

Confirm model compatibility

Match part fitment to your mower, tractor, or implement model and engine type to avoid returns and ensure proper function

Prefer OEM or OEM-equivalent parts

OEM or manufacturer-equivalent kits and starters typically match original specs and simplify maintenance for common engine brands

Check spline and shaft specs

For PTO shafts and extenders verify spline count and diameter (e.g., 1-3/8" 6-spline) and overall length to ensure driveline compatibility

Inspect mounting and electrical connections

For starters and electrical replacements confirm bolt pattern, gear teeth count, and voltage to match starter motors and solenoids

Choose attachments by capacity

Select hay spears and forks by tine length and load capacity to match bale size and loader hydraulic ratings
