What the 499 Haybine Mower Conditioner is used for
The 499 cuts a broad swath of hay and feeds it through rubber conditioning rolls before forming a windrow. Its pivot tongue permits mowing on either side of the tractor, helping reduce deadhead passes. It is commonly used where a sickle-bar cut and roll conditioning are preferred for hay crops.
Why the New Holland 499 Haybine Mower Conditioner stands out
The 499 pairs a 12 ft 3 in. sickle header with a pivot-tongue layout for efficient field patterns. Its dual sickle assemblies and enclosed gearbox drive were designed for the wider header. Independent header flotation of the conditioning rolls helps the header follow uneven ground.
Buying a used New Holland 499 Haybine Mower Conditioner
Inspect both sickle assemblies, guards, hold-downs, wobble or gearbox drive components, and cutterbar alignment. Check rubber rolls for cracking, missing rubber, separation, and adequate pressure adjustment. Test the hydrostatic drive, PTO shaft, hydraulic hoses and cylinders, pivot tongue, and flotation components before buying.
