Mechanical Restoration: John Deere 1326 & 1327 Impeller Mower-Conditioners
High-speed hay harvesting places unrelenting physical stress on the cutterbar and conditioning systems of your equipment. The John Deere 1326 and 1327 mower-conditioners are engineered to slice through dense forage and accelerate dry-down using an aggressive impeller system. However, the combination of high rotational speeds and abrasive crop contact eventually wears out the modular cutterbar gears, shatters conditioner tines, and fatigues the main drive gearboxes. When a mower disc develops excessive play or the impeller rotor requires new bearings, field-expedient fixes often lead to catastrophic failures. The John Deere 1326 and 1327 Mower-Conditioners Technical Service Manual (TM3260) is the factory-authorized "wrenches-on-iron" blueprint required to dismantle, repair, and reconstruct these implements.
Sourcing this mechanical authority from manualsmarket.com allows your agricultural workshop to manage intensive off-season rebuilds. Your technicians gain immediate access to the exact gear lash measurements, shaft alignments, and hardware extraction protocols needed to conduct comprehensive mower-conditioner overhauls entirely in-house.
Structural Overhaul & Component Teardown
This technical publication strictly bypasses digital diagnostic theory, providing actionable, step-by-step mechanical repair data for the machine's primary systems:
- Modular Cutterbar Reconstruction: Restore flawless cutting performance. The manual provides the exact internal teardown protocols for the modular gear-driven cutterbar, including gear shimming procedures, bearing preload settings, and the precise timing required between adjacent mower discs.
- Impeller Conditioning Rotor: Maintain aggressive forage processing. Access the heavy rigging and extraction sequences necessary to remove the massive impeller rotor, replace worn or bent conditioning tines, and balance the assembly to eliminate harmful vibration.
- Drivelines & Primary Gearboxes: Secure the machine's power transfer. Navigate the complete internal teardown of the main bevel gearboxes. Evaluate shaft end-play, set correct bearing preloads, and refurbish the friction slip clutches to protect the tractor's PTO.
- Conditioning Hood & Swathing Gates: Ensure uniform windrow formation. Follow the instructions for repairing the conditioning hood adjustment linkages and replacing the hardware for the swathing gates and windrow shields.

Field Mechanic Service FAQ
Q: Does this document include the hydraulic schematics for the lift cylinders?
A: While this Technical Service manual covers the physical disassembly and seal replacement of the hydraulic cylinders, complex diagnostic troubleshooting of the hydraulic circuit is often found in the Operation and Tests manual. This TM3260 file is focused on heavy hardware and mechanical rebuilding.
Q: Will this manual help me repair the internal gearbox of the tractor powering the mower?
A: No. This technical volume is authored exclusively for the 1326 and 1327 mower-conditioner implements. Working on the tractor's transmission, PTO engagement, or engine requires the dedicated service manual for your specific tractor model.
Q: Are specific torque values provided for the mower disc bolts?
A: Absolutely. Because mower discs operate at extremely high RPMs, the document provides mandatory torque charts and specific fastening sequences to ensure the blades and discs stay securely attached during operation.
