Moog's 1900 Series - PTO Replacements for the Domestic Standard Series 6

ASAE Category 1: 13HP @ 540RPM and 20HP @ 1000RPM

A power take-off, or PTO, is a kind of drive shaft that draws energy from the engine and powers an application on the other end. This set-up is typically found on tractors or commercial vehicles. Moog's premium PTO replacements are:

  • Innovative - Designed by the same Moog Automotive Part Engineers
  • Durable - Specifically built for the rough and tough life of agricultural and heavy-duty applications
  • Safer - Built with forged and hardened materials for strength and durability
  • Easier - Designed for the aftermarket service environment

The part numbers below work for the Domestic Standard Series 6 for ASAE Category 1: 13HP @ 540RPM and 20HP @ 1000RPM.

Moog also has a line of Lawn and Garden Products for this series.
