TM1079 John Deere 700 and 750 Grinder-Mixers Pdf Technical Service Manual

Controlling Livestock Rations: JD 700 & 750 Grinder-Mixers

Achieving feed independence on a livestock operation requires reliable milling and blending equipment. The John Deere 700 and 750 grinder-mixers were built to process thousands of bushels of grain, utilizing high-speed hammermills to pulverize corn and heavy vertical augers to thoroughly blend custom feed rations. This continuous processing of abrasive grains and heavy supplements subjects the internal flighting, mill bearings, and right-angle gearboxes to extreme friction and intense kinetic vibration. When a shattered hammermill bearing or a seized unloading auger halts your daily feeding schedule, you cannot rely on guesswork to repair the implement. The John Deere 700 and 750 Grinder-Mixers Technical Service Manual (TM1079) is the essential, uncompromising physical blueprint required to reconstruct this vital feed processing machinery.

Sourced directly from the agricultural equipment archives at manualsmarket.com, this factory-authored mechanical guide equips your farm mechanics with the precise hardware extraction sequences, structural alignments, and critical lifting tolerances established by the original engineers. Rebuilding your grinder-mixer to these rigorous OEM standards ensures aggressive grain milling, perfectly blended rations, and maximum reliability when your livestock depend on daily feed delivery.

Core Feed Processing Teardowns

This technical service archive entirely bypasses electronic scale troubleshooting, directing its specialized focus strictly toward the heavy wrenching and hardware reconstruction of the grinder-mixer's primary mechanical zones:

• Hammermill & Grinding Chamber: Safely manage the extreme rotational mass of the primary mill. The manual details exact procedures for replacing worn reversible hammers, swapping sizing screens, rebuilding the heavy-duty main rotor shaft bearings, and physically balancing the assembly to prevent self-destructive vibration.
• Vertical Mixing Tank & Augers: Maintain a perfectly blended feed ration. Navigate the physical teardown of the massive central mixing auger, replace abrasive-wear components like the auger flighting, and rebuild the lower thrust bearings that support the entire weight of the feed batch.
• Intake & Discharge Conveyance: Ensure uninterrupted grain flow into and out of the mixer. Discover the teardown steps to safely extract the swinging intake augers, rebuild the long discharge folding augers, and overhaul the mechanical linkages that engage the unloading process.
• PTO Power & Drive Belts: Reconstruct the tractor-driven power delivery network. The guide covers the mechanical unbolting of the main PTO driveline, rebuilding crucial protective slip clutches, and completely overhauling the heavy multi-belt tensioning systems that split rotational power between the mill and the augers.

Workshop Clarifications (TM1079 Boundaries)

Mechanic Inquiry: Will this manual help me troubleshoot the electronic weighing scales and load cells?
Factory Guideline: No. The electronic batch scales, load cell wiring, and digital monitor diagnostics are exclusively documented in the companion Diagnostic, Operation, and Test manual. This TM1079 publication handles physical hardware replacement, mechanical teardowns, and iron reassembly exclusively.

Mechanic Inquiry: Are specific tightening torques provided for the hammermill rotor?
Factory Guideline: Absolutely. Because the hammermill rotor operates at extremely high RPMs to shatter grain, the manual provides mandatory torque tightening charts and hardware grade requirements for the hammer retaining pins and main shaft to prevent explosive hardware failure during operation.

Mechanic Inquiry: Does this guide cover the repair of the wheel hubs and implement frame?
Factory Guideline: Yes. The mechanical unbolting, bearing repacking, and structural axle realignment for the primary transport wheels and the main implement tongue are fully detailed within this physical repair archive.
