NEW 2PCS Knotter Gear Set Fit for New Holland BC5070 Square Hay Baler
Knotter drive gear set, designed as a direct replacement for New Holland BC5070 series square hay and straw balers, available in bevel gear, worm gear and pinion options. Installed in the knotter drive train, transmits power through gear meshing, and drives all knotter components to complete twine clamping, looping, knotting and cutting in precise sequence. Precision machined from high-strength wear-resistant steel with accurate tooth profile, delivers reliable impact resistance and long service life for continuous field operation. Replace when gear teeth show excessive wear, chipping, deformation, drive skipping, out-of-sequence knotting, frequent missed knots or mechanism jamming. Full set replacement for the same knotter side is recommended to maintain precise meshing fit; inspect meshing clearance and apply lubrication during replacement. Continued use of worn gears will cause inaccurate knotting timing, increase knot failure rate and may damage other knotter drive components. Restores accurate knotter timing and smooth power transmission, eliminates missed knots and jamming, and improves overall knotting success rate. High-strength wear-resistant steel construction extends service life and reduces maintenance frequency. Full set replacement ensures proper meshing clearance, reduces wear on mating components and improves baler operation reliability.
