New Holland 2355, 2358 Disc Auger Header Service Pdf Manual

New Holland 2355, 2358 Disc Auger Header Service PDF Manual (P. Nb. 87032364)

Harvest efficiency often depends more on the header than the combine itself. The New Holland 2355 and 2358 Disc Auger Headers were engineered to deliver aggressive crop cutting, dependable auger feeding, and stable harvesting performance across demanding grain and soybean conditions. Combining high-speed disc cutting systems with durable auger-feed technology, these headers were designed to improve feeding consistency while minimizing crop bunching and harvest losses in varying field conditions. Unlike draper platforms focused on belt feeding, the 2355 and 2358 models utilize robust auger systems that provide smooth crop transfer into the feeder house while maintaining reliable performance in tough, tangled, or uneven crops. This official Service PDF Manual with publication number 87032364 contains complete factory repair procedures covering disc cutterbar assemblies, auger-drive systems, hydraulic components, reel mechanisms, gearbox diagnostics, electrical troubleshooting, crop-flow adjustments, and complete workshop servicing instructions.

Auger Feed Systems & Crop Transfer Diagnostics

The auger system plays a major role in maintaining even crop flow from the cutterbar into the combine feeder house. Proper auger timing and feeding adjustment are essential for reducing plugging and maximizing harvesting efficiency.

• Auger-flight wear inspections and feed-timing adjustments
• Center-feed transition diagnostics and crop-flow troubleshooting
• Retractable finger servicing and operational calibration
• Auger bearing replacement and rotational alignment procedures
• Crop bunching diagnostics and feeder consistency analysis
• Drive-chain servicing and auger-drive tension adjustments
• Feeder-house transition inspections and material-flow testing
• Operational crop-feed analysis under heavy harvest conditions

These workshop procedures help technicians diagnose uneven feeding, auger vibration, excessive crop wrapping, and feeder interruptions during high-volume harvesting operations.

Disc Cutterbar Assemblies & Knife Drive Repairs

The 2355 and 2358 headers use high-speed disc cutting technology designed to maintain clean cutting performance while operating efficiently in dense soybean fields and heavy grain crops.

• Disc cutterbar disassembly and internal module inspections
• Knife replacement procedures and cutting-angle adjustments
• Cutterbar lubrication servicing and seal replacement workflows
• Disc-drive vibration diagnostics and rotational balance analysis
• Skid-plate servicing and cutting-height calibration
• Impact-damage inspections and cutterbar housing repairs
• Knife overlap verification and operational timing checks
• Field-cut quality diagnostics and harvesting performance analysis

Detailed cutterbar repair procedures assist mechanics in correcting rough cutting performance, excessive vibration, damaged disc modules, and crop-loss conditions caused by improper cutting setup.

Reel Operation, Header Drives & Hydraulic Controls

Efficient reel performance and stable hydraulic control are essential for maintaining proper crop feeding across varying harvesting speeds and changing crop conditions.

• Hydraulic reel-speed diagnostics and pressure testing
• Reel-position calibration and operational adjustment procedures
• Drive-belt inspections and header-drive servicing workflows
• Hydraulic leak detection and control-valve troubleshooting
• Reel finger inspections and timing adjustment procedures
• Header lift-system diagnostics and operational analysis
• Hydraulic-flow testing and circuit troubleshooting
• Drive-shaft servicing and operational vibration diagnostics

The hydraulic and drive-system sections provide dealership-level procedures for troubleshooting unstable reel speed, weak lift response, drive-system vibration, and hydraulic pressure fluctuations.

Header Frame, Structural Components & Field Adjustments

Headers operating in rough field conditions experience continuous stress from uneven terrain, crop loads, transport movement, and seasonal harvesting pressure.

• Header-frame inspections and structural alignment procedures
• Transport-lock servicing and operational adjustment workflows
• Wear-plate inspections and frame-support diagnostics
• Field-leveling adjustments and flotation calibration procedures
• Shield servicing and safety-component inspections
• Mounting-point repairs and feeder connection analysis
• Operational transport diagnostics and vibration testing
• Header setup procedures for varying crop conditions

The structural repair section helps technicians maintain safe operation, proper feeder alignment, and stable harvesting performance throughout demanding field conditions.

Built for Consistent Grain & Soybean Harvesting Performance

The New Holland 2355 and 2358 Disc Auger Headers were developed for producers requiring dependable crop feeding, aggressive cutting performance, and efficient material handling during intensive harvesting seasons.

Their high-speed disc cutting systems, durable auger-feed design, responsive hydraulic controls, and rugged structural construction made them highly effective for soybean harvesting, grain operations, and high-acreage combine applications.
