About Agriculture Gearboxes
Agriculture gearboxes are right-angle and in-line gear drives that adapt the tractor power take-off (PTO) to the speed, torque and direction an implement needs. Most are 90-degree bevel-gear units that take a 540 or 1000 rpm splined PTO input and redirect it through a spiral-bevel or straight-bevel set to a horizontal or vertical output, either stepping speed down for high-torque tillage or up for high-speed rotors and cutters. Reduction (or step-up) is set by the bevel gear pair, typically in the range of about 1:1 to 1:3 per stage, with multi-stage and parallel-shaft variants for larger machines.
The family spans rotary-tiller and rotavator gearboxes, multi-speed PTO drives, harvester header and threshing drives, mower, mulcher, post-hole-digger, feed-mixer and irrigation-pump gearboxes. Typical input torque runs from roughly 80 Nm on small implements to 850-1000 Nm and beyond on heavy tillage and large harvesters, with power ratings broadly from about 10 to 150 HP. Bevel and helical gearing is commonly cut to ISO 1328 / AGMA 2015 quality grades and load-rated to AGMA 2001/2101 or ISO 6336 where engineering data is required.
Construction centres on case-hardened alloy-steel gears (20MnCr5, 20CrMnTi or 18CrNiMo7-6), gas-carburised, quenched and ground or lapped, running in rigid grey cast-iron or ductile-iron housings; aluminium housings appear on lighter machines for heat dissipation. Tapered roller bearings, oil seals and IP65-class sealing suit dusty, wet field conditions, with mineral or PAO ISO VG 220/320 lubrication.
Units are configured by ratio, input spline (1-3/8" Z6 or Z21, 1-3/4" Z20), shaft or flange output, mounting and shear-protection options. Himalay's MSME partners manufacture agriculture gearboxes with gear-rating to AGMA/ISO 6336 where engineering data is required, ISO 9001 quality systems, load and efficiency test reports and material traceability; CE (Machinery Directive) and SABER (Saudi Arabia) are coordinated as part of the standard order flow.
