TM3224 John Deere Impeller 1320 Mower-Conditioners Pdf Technical Service Manual

Mechanical Restoration: John Deere 1320 Impeller Mower-Conditioner

Forage quality depends on a clean cut and rapid moisture loss, making the performance of your mower-conditioner vital to your haying operation. The John Deere 1320 utilizes a high-speed cutterbar and an aggressive impeller conditioning system to process heavy crops efficiently. However, the high-vibration environment and abrasive crop contact will eventually lead to gear wear in the cutterbar, bearing fatigue in the conditioning rotor, and seal failure in the main gearboxes. When a modular disc unit requires internal repair or the impeller system needs a total overhaul, the John Deere 1320 Mower-Conditioner Technical Service Manual (TM3224) provides the authoritative "wrenches-on-iron" blueprints required to reconstruct the machine to factory specifications.

Available through manualsmarket.com, this comprehensive mechanical reference allows your agricultural service team to take full control of off-season maintenance. By utilizing precise gear lash measurements and hardware extraction sequences, you can minimize the risk of catastrophic field failures during the harvest rush.

Structural Overhaul & Hardware Teardown

This technical publication focuses strictly on physical hardware intervention, providing actionable, step-by-step mechanical repair data for the machine's primary systems:

• Modular Cutterbar Rebuilding: Ensure a perfect cut across the entire width of the machine. The manual details the internal teardown of the gear-driven cutterbar, including specific gear shimming procedures, bearing preloads, and the precise mechanical timing required between adjacent mower discs.
• Impeller Conditioning Rotor: Restore aggressive forage processing. Access the heavy rigging protocols necessary to extract the conditioning rotor, replace worn or shattered tines, and balance the assembly to prevent machine-damaging vibration.
• Main Drive Gearboxes & PTO: Secure reliable power transfer from the tractor. Navigate the complete internal teardown of the primary bevel gearboxes. Evaluate shaft end-play, set correct bearing preloads, and service the friction slip clutches.
• Hydraulic Lift & Frame Components: Maintain structural integrity and ground following. Follow instructions for replacing pivot bushings, overhauling lift cylinders, and repairing the conditioning hood adjustment linkages.

Field Maintenance Q&A

Does this manual cover the electrical troubleshooting for the cab monitor?
No. Diagnostic trouble codes, sensor logic, and electrical schematics are documented exclusively in the Operation and Tests manual. This TM3224 file is reserved for physical structural repair, gear rebuilding, and mechanical timing of the implement.

Are specific torque values provided for the high-speed cutterbar hardware?
Absolutely. Given the extreme centrifugal forces involved, the manual provides mandatory torque charts and specific fastening patterns for mower discs and knife bolts to ensure safe operational limits.

Can I use this manual to rebuild the engine of the tractor I use to pull the 1320?
No. This technical volume is authored exclusively for the 1320 mower-conditioner. Overhauling the tractor's engine, transmission, or PTO system requires the dedicated service manual for that specific tractor model.
