Whether repairing the crop feeding mechanism, servicing hydraulic components, rebuilding drive assemblies, or troubleshooting electrical faults, every procedure follows official New Holland workshop standards to restore factory performance.

Designed for Efficient Grain Harvesting

The 300FP and 380FP platforms are built to deliver smooth crop intake while minimizing grain loss in cereals and other small grain crops. Their large-diameter auger, adjustable reel system, and heavy-duty frame work together to provide consistent feeding into the feeder housing, even during heavy crop conditions. Hydraulic header functions and durable mechanical drive components allow operators to maintain high harvesting efficiency while reducing downtime during peak harvest periods.
