Part Number Table — Complete Assembly and Halves

The complete assembly is the part number to order when both halves are being replaced. If only the tractor half or the implement half is worn, the half-shaft number is the one to match. The two halves are listed separately because the CV angle differs between the tractor side and the discbine side. For other disc mower applications, see the PTO shaft for discbines category.

Product Parts — Reference Numbers for Service Replacement

The parts table is for service replacement of individual components. When ordering a complete replacement shaft, use the assembly part number in the previous table. The broader PTO shaft range lists other agricultural driveline categories.

Clutch Behaviour — What the 2,800 N·m Setting Protects

The 2,800 N·m slip torque is the figure stated in the supplied product material. Confirm the setting against the disc mower model and the tractor PTO before ordering. For the matching implement driveline, see the PTO shaft for New Holland discbines page as a cross-reference for discbine-side configurations.

Before You Request a Quotation

1. Confirm the mower model and the existing part number

   Disc Mower 1340, Hesston 1340/1345, select CaseIH 8312, Massey Ferguson PTD 12 and New Idea 5512 are the compatibility references in the supplied material. The existing shaft part number is the fastest way to confirm the replacement.

2. Confirm the tractor PTO spline

   The complete assembly 14656849 is listed with a 1.375-21 tractor connection. If the tractor uses a different PTO stub, confirm the tractor half separately using 83-14656849 or the equivalent.

3. Confirm the implement connection

   The implement side is listed as a 1.5" RD clamp in the complete assembly and in the implement half 82-14656849. If the discbine input uses a different clamp or yoke, confirm the implement half before ordering.

4. Confirm the slip torque and clutch condition

   The clutch is set at 2,800 N·m in the supplied material. If the existing clutch has been adjusted or the mower runs a different gearbox, confirm the slip setting against the mower manual before the replacement is quoted.

MOQ, customization and lead time are quoted per order because they depend on whether the order is for a complete assembly or a half-shaft, and whether the connection sizes match the standard part numbers. Nothing on this page commits to a fixed MOQ or lead time that would not hold for a different configuration. For a related driveline category, see the PTO shaft for feed mixers range.
