PTO Shaft Sub-Assy, #55 80Deg CV w/27" Shaft

Tractor Half CV PTO Shaft Assy, #55

The 15656800 Tractor Half CV PTO Shaft Assembly (#55) is a heavy-duty, wide-angle driveline built to deliver smooth, uninterrupted power through demanding operating conditions. Featuring an 80° constant velocity (CV) joint, it eliminates the vibration and speed fluctuations common with standard PTO shafts, allowing equipment to operate efficiently even at sharp angles. Built with high-strength components and a fully shielded guard system, this shaft is designed for reliability, safety, and long service life—because when your PTO runs right, everything else tends to follow.
