Case IH 1250, 1350 Grinder Mixer Pdf Service Repair Manual

Case IH 1250, 1350 Grinder Mixer PDF Repair Service Manual

Livestock performance begins with consistent feed preparation. Whether producing dairy rations, beef feed, swine diets or mixed grain supplements, the quality of the finished feed depends on uniform grinding, accurate ingredient mixing and reliable unloading. The Case IH 1250 and 1350 Grinder Mixers were engineered to process large volumes of grain efficiently by combining a high-capacity hammer mill, precision mixing tank and dependable auger delivery system into one versatile machine for daily feed production.

Because grinding, conveying and mixing occur simultaneously, every mechanical system must remain correctly adjusted to maintain productivity. Hammer mill components, drive shafts, augers, mixing paddles, hydraulic functions and unloading mechanisms all require periodic inspection and accurate servicing. This OEM Factory Repair Service Manual provides dealership-level repair procedures for the Case IH 1250 and 1350 Grinder Mixers, covering diagnostics, inspection, disassembly, overhaul, adjustment and operational testing. The official workshop publication guides technicians through complete service procedures for the hammer mill, feed mixing system, augers, PTO driveline, hydraulic circuits, unloading equipment and structural components using factory-approved repair methods.

Machine Specifications

Efficient Feed Processing Depends On Proper Machine Timing

Unlike conventional agricultural implements, a grinder mixer must grind, convey and blend materials in a continuous process. Worn hammers, damaged screens, improperly adjusted augers or driveline vibration can reduce grinding efficiency and produce inconsistent feed mixtures. Professional technicians therefore inspect hammer wear, screen condition, auger flighting, gearbox operation and PTO alignment before replacing major assemblies.

The workshop procedures in this manual follow a logical service sequence beginning with troubleshooting and component inspection before progressing through measurements, rebuilding, adjustments and operational verification. This approach minimizes downtime while restoring reliable feed production throughout demanding livestock feeding seasons.
