Warner 5219-79 PTO Clutch Cross-Reference Guide

Overview

If you're searching for Warner 5219-79, you're likely replacing an electric PTO clutch on an MTD-built riding mower, lawn tractor, or related residential mower platform.

Warner numbers are often stamped directly on the clutch body, while the mower parts diagram may show an MTD, Cub Cadet, Troy-Bilt, or private-label OEM number. This can make the replacement process confusing if your original clutch shows 5219-79 but your mower diagram references 717-04174 or 917-04174.

This guide helps route Warner 5219-79 searches to the correct 717-04174 / 917-04174 PTO clutch replacement path.

Why Buyers Search Warner 5219-79

Many buyers find 5219-79 stamped on the original clutch but cannot find that number in the mower parts diagram. The parts diagram may list the OEM number instead, such as 717-04174, 717-04174A, 917-04174, or 917-04174A.

This is why the safest replacement path is to cross-reference the Warner number to the correct OEM route, then confirm the pulley diameter, bore size, rotation, connector style, and mower application.

Important Fitment Check

Do not order a PTO clutch by appearance alone. PTO clutches can look similar while using different pulley offsets, wiring connectors, anti-rotation setups, or deck belt geometry.

Before ordering, verify:

  • Original stamped clutch number
  • OEM mower part number if available
  • Crankshaft bore size
  • Pulley diameter
  • Rotation direction
  • Connector style
  • Anti-rotation bracket or tab setup
  • Deck belt routing
