New Holland 2331, 2332 Disc Header For TV140 Pdf Repair Service Manual (p. Nb. 86643834)

New Holland 2331, 2332 Disc Header for TV140 PDF Repair Service Manual (Publication No. 86643834)

Unlike conventional front- or rear-mounted mower-conditioners, the New Holland 2331 and 2332 Disc Headers were specifically engineered for the TV140 Bi-Directional Tractor, allowing operators to work with excellent forward visibility while maintaining balanced machine weight and efficient crop flow. This unique mounting system improves maneuverability in irregular fields and enables high-capacity mowing with reduced operator fatigue.

The disc cutterbar, conditioning system, header driveline, flotation suspension and hydraulic lift mechanisms are subjected to continuous impact loads while operating across uneven terrain. Maintaining factory performance requires accurate adjustment of cutterbar timing, conditioner clearance and hydraulic components. This OEM Factory Repair Service Manual (Publication No. 86643834) provides dealership-level procedures for diagnostics, inspection, adjustment and complete component overhaul, helping technicians restore dependable cutting performance before every hay season.

Designed Specifically for the TV140 Bi-Directional Tractor

The 2331 and 2332 headers were not designed as stand-alone mower units. They integrate directly with the TV140's bi-directional operating concept, placing the header at the leading end of the machine during field operation. This configuration improves crop visibility, reduces crop contamination and provides smoother weight distribution compared with conventional pull-type mower-conditioners.
