The Weasler AB5 Series MX shaft (Part # 14106558ST) is a direct-replacement Power Take-Off (PTO) drive shaft for rotary cutters, including Rhino, Land Pride, and Woods models.
-
It replaces John Deere part numbers AW30401 and AW30402.
-
An 8,000 in-lb friction clutch is included for overload protection. The shaft meets all applicable regional ASABE Standards.
-
The tri-lobe telescoping design supports adjustable and cut-to-length configurations.
When a rotary cutter PTO shaft wears out or fails, it takes the whole machine with it. Shafts on Rhino, Land Pride, and Woods cutters absorb continuous load across rough terrain and full-arc swings, and a worn or undersized replacement just accelerates the next failure. The Weasler AB5 Series Profile Power Take-Off (PTO) Drive Shaft is a direct-fit aftermarket replacement that includes a friction clutch for overload protection and a tri-lobe telescoping profile that can be adjusted or cut to length.
What Is the MX Rotary Cutter PTO Drive Shaft?
The Weasler AB5 Series MX shaft (Part # 14106558ST) is an aftermarket PTO drive shaft designed for all-purpose rotary cutter applications. It uses a tri-lobe profile telescoping design that resists twisting and handles the continuous load demands of field cutting operations. The shaft is built to Weasler's AB5 Series specifications and meets all applicable regional ASABE (American Society of Agricultural and Biological Engineers) Standards.
Which Rotary Cutter Models Is It Compatible With?
The AB5 Series MX shaft fits several widely used rotary cutter brands, including Rhino, Land Pride, and Woods. It is a direct replacement for John Deere part numbers AW30401 and AW30402. Customers with engineering and application support needs can access Weasler's customer-dedicated support through Royal Brass & Hose.
What Are the Key Specifications?
The shaft includes a 1 3/8-6 spline spring-lok tractor connection and a 1 3/8-21 spline clamp implement connection. Compressed overall length (OAL) is 58.5 inches. The included friction clutch is rated at 8,000 in-lb and provides overload protection, heat dissipation, and torque balancing at the implement end. A spring-loaded collar tractor yoke allows for fast connection without tools.
Can the Shaft Be Cut to Length?
Yes. The tri-lobe profile telescoping construction supports both adjustable-length and cut-to-length configurations. This makes it practical for installations where the standard OAL does not match the tractor-implement spacing. For step-by-step cutting instructions, see the RBH guide on how to cut a PTO shaft.
