Tractor Half PTO Shaft Assy, #55, 1-3/8-6Spl 80Deg CV

Tractor Half CV PTO Shaft Assy, #55

The 15556800 Tractor Half CV PTO Shaft Assembly (#55) is a heavy-duty, wide-angle driveline engineered for smooth, consistent power delivery in demanding equipment applications. Featuring an 80° constant velocity (CV) joint, this shaft eliminates the vibration and speed fluctuations found in standard PTO shafts, allowing your equipment to run efficiently even at sharp angles. Built with high-strength components and full-coverage shielding, it’s designed for long-lasting performance, safety, and reliability—because a smooth-running PTO makes everything else go a lot better.
