New Holland P2350, P3440, P3550, P4460, P4580, P4760, P4950 Air Cart Pdf Repair Service Manual (p. Nb. 47827462)

New Holland P2350, P3440, P3550, P4460, P4580, P4760, P4950 Air Cart PDF Repair Service Manual (Publication No. 47827462)

Consistent seed placement starts long before the opener reaches the soil. On a modern air seeding system, the air cart controls product metering accuracy, air delivery, seed distribution and fertilizer application. A worn metering drive, hydraulic fault or calibration error can result in uneven emergence and costly yield losses across hundreds of acres. The New Holland Flexi-Coil P2350, P3440, P3550, P4460, P4580, P4760 and P4950 Air Carts were engineered to deliver high-capacity, variable-rate seeding with exceptional distribution accuracy, making proper workshop repairs essential for maintaining field performance.

This OEM Factory Repair Service Manual (Publication No. 47827462) is written specifically for these P-Series Air Carts and provides the same repair information used by New Holland dealership technicians. It covers complete diagnostics, hydraulic testing, metering system repairs, axle servicing, electrical troubleshooting, calibration procedures and complete component overhaul using official factory specifications.

Purpose-Built for Precision Seeding

The Flexi-Coil P Series was developed for producers who require maximum acreage capacity with precise product delivery. The model range includes capacities from 350 to 950 bushels, available in two-, three- and four-compartment configurations, allowing multiple seed and fertilizer products to be applied during a single pass. IntelliRate™ variable-rate metering, durable polyethylene tanks, efficient air delivery and flexible tow-between or tow-behind configurations make these carts suitable for large-scale farming operations.
