9988 Series Bareco Constant Velocity Drivelines. 80 Degree Wide Angle Drive Shafts rated from 35hp to 200hp

Bareco Constant velocity (CV) drivelines are wide-angle PTO drive shafts with an 80-degree articulation at the tractor end. Unlike a standard universal joint, which causes velocity fluctuation through the joint at steep angles, the CV joint delivers smooth, constant velocity output regardless of the angle, allowing tighter turning circles without vibration or power surges.

These shafts are suited to towed implements, front-mounted attachments, or any application where the implement frequently turns or operates at a significant angle to the tractor.

Most variants have 1 3/8" x 6 spline yokes both ends. The W671306134 and W67130620 use 1 3/4" spline on one end for high-HP applications. Custom yoke combinations and slip clutch additions are available on request. Do not exceed the 80-degree maximum angle — a turning limiter on the implement drawbar is recommended. Patented lever-release guard included.

Warning: Exceeding the maximum operating angle will cause CV joint failure and is not covered under warranty.
