New Holland 1411, 1412 Disc Mower Conditioner Pdf Repair Service Manual (p. Nb. 86630282)

New Holland 1411, 1412 Disc Mower Conditioner PDF Repair Service Manual (Publication No. 86630282)

The New Holland 1411 and 1412 Disc Mower Conditioners were developed for producers who need high daily mowing capacity without compromising forage quality. Built with a heavy-duty modular disc cutterbar and an efficient conditioning system, these machines deliver fast, clean cutting while accelerating crop dry-down. Whether harvesting alfalfa, clover, ryegrass or mixed forage, the 1411 and 1412 are designed to maintain uniform stubble height, consistent conditioning and smooth crop flow even in dense, high-moisture fields.

Continuous field operation exposes the cutterbar, disc modules, conditioner rolls, PTO driveline, suspension system and hydraulic lift components to significant wear. Proper servicing requires more than replacing worn parts—it demands accurate timing, factory adjustments and systematic inspection procedures. This OEM Factory Repair Service Manual (Publication No. 86630282) provides dealership-level repair instructions covering diagnostics, component overhaul, calibration, adjustments and testing to help restore original cutting performance while minimizing costly harvest downtime.
