PTO Shaft for Flexwing Mower

A PTO shaft for a flexwing mower serves as the primary mechanical link that transfers rotational power from a tractor’s rear power take-off directly to the mower’s gearboxes. Engineered for heavy-duty applications on models from Bush Hog, John Deere, Schulte, and Woods, these shafts deliver consistent torque to both the central deck and the folding wing sections, enabling the rotary blades to cut large swaths of vegetation with precision. Constructed from high-strength steel tubing with telescoping sections and constant-velocity joints, the assembly flexes smoothly as the wings raise and lower during transport or operation over uneven terrain. Built-in slip clutches and protective shielding further guard against overloads from debris impacts or abrupt stops, minimizing downtime in roadside, pasture, or right-of-way maintenance. Proper sizing—typically Category 4 or 5—along with regular lubrication and inspection, ensures long-term reliability and safe performance across demanding field conditions.
