Bevel Gear Drive Principle

Power from the tractor’s 540 rpm PTO shaft enters through the 1 3/4 Z20 spline input. The spiral bevel gear set — 19 drive teeth meshing with 13 driven teeth — changes the rotation axis from horizontal to vertical while simultaneously increasing output shaft speed by a factor of 1.46. The precisely ground tooth profiles maintain full contact under varying load conditions, reducing noise and heat generation even during sustained high-power cutting cycles.

Materials & Construction

The main housing is pressure-cast from high-grade grey iron (GG25/HT250), offering excellent vibration damping and corrosion resistance in wet British field conditions. All internal gear blanks are machined from 20CrMnTi alloy steel, carburised and hardened to HRC 58-62 on the tooth surface, giving exceptional contact fatigue strength. Output shaft seals use double-lip nitrile rubber rated to 120°C, preventing contamination ingress from mud, crop residue, and standing water common on UK farmland during autumn and winter operations.

Lubrication & Sealing

The HC-RC130-146 agricultural gearbox operates on a splash-lubrication system using ISO VG 460 gear oil, pre-filled at factory to the correct level. A magnetic drain plug retains metallic wear particles, simplifying inspection and extending service intervals to approximately 500 operational hours under normal UK mowing conditions. The oil-fill and breather plug positions are optimised for common mounting angles, and a dipstick port allows quick level checking without removing covers — a practical advantage appreciated by machinery mechanics servicing equipment in the field.

Rotary Slashers & Flail Mowers

The most common fit across UK verge management and grassland renovation machinery, the agricultural gearbox drives blade carriers up to 3.5 m wide at the elevated tip speeds needed for clean, single-pass cutting.

Multi-Disc Mowers (Silage)

Dairy and beef farms across Northern England, Wales, and Ireland rely on high-power disc mower drive systems for rapid silage harvesting. The 130 HP rating comfortably covers demand from wide-front three-disc cutting heads.

Sugarcane Elevator Drive Systems

For high-capacity cane harvesting operations, elevator and slew drive demand precise, high-torque gearbox engineering. Learn how rotary cutter gearboxes integrate into harvester platforms: Kotak Gear Pembunuh Lif Presisi untuk Penuai Tebu Berkapasiti Tinggi.

Sugarcane Base Cutter Drives

Base cutter gearboxes face extreme shock loading at ground level during harvesting. Our engineering guides explain the performance demands and design solutions in detail: Kotak Gear Pemotong Asas untuk Penuai Tebu: Kuasa Ketepatan untuk Potongan Paling Sukar.

Stubble Cultivation Implements

Post-cereal harvest stubble management in the UK Midlands and East Anglia frequently employs heavy rotary cultivators. The agricultural gearbox provides the rated torque and shock-load tolerance needed in stony, compacted soils.

We replaced the original gearboxes on three of our Twose 7.5 m gang mowers with HC-RC130-146 units midway through last season. They handled the heavy autumn roadside growth in Lincolnshire without any heat-related issues. Oil stays cleaner than our previous units, and the spline fit on our New Holland T7 series was perfect first time. A solid buy at the price point.

Our workshop in Aberdeenshire builds replacement drive assemblies for Amazone and Pottinger disc mowers. We trialled the HC-RC130-146 agricultural gearbox across six rebuilds last winter. Gear finish quality is impressive, documentation for CE compliance came without chasing, and the custom shaft length we requested was delivered within the agreed four weeks. Our customers are happy and we have placed a standing order for 30 units per quarter.

As a dealer covering South Wales and Herefordshire, I needed a reliable source of rotary cutter gearboxes for aftermarket sales and warranty replacements. The HC-RC130-146 ticks every box — good gear hardness figures, standard spline sizes, and a price that leaves margin. The factory shipped a pre-production sample within two weeks, which made it easy to get buy-in from our service manager before committing to stock.

Q: What is the best agricultural gearbox supplier in the UK for heavy-duty rotary cutter applications on high-horsepower tractors above 100 HP?

For high-horsepower UK tractor applications above 100 HP, you need an agricultural gearbox rated to handle 130 HP or more at 540 rpm PTO input, with hardened spiral bevel gears and sealed bearings suited to British field conditions. The HC-RC130-146 is a direct-fit solution used by UK contractors and machinery dealers across England, Scotland, and Wales. Contact our sales team for pricing and availability specific to the UK market.

Q: How much does it cost to buy an HC-RC130-146 rotary cutter gearbox for UK agricultural machinery importers, and what is the minimum order quantity?

Pricing for the HC-RC130-146 agricultural gearbox depends on order quantity, customisation requirements, and current shipping terms to UK ports. We supply from as low as 1 unit for sample evaluation, with volume pricing available from 10 units. Send your enquiry with the required quantity to [email protected] and our UK export team will respond with a detailed quote within 24 hours.

Q: Which John Deere or New Holland tractor PTO shaft spec is compatible with the HC-RC130-146 agricultural gearbox input shaft used across UK arable farms?

The HC-RC130-146 agricultural gearbox uses a 1 3/4 Z20 spline input — the standard Category 3 PTO profile used on tractors from 100 HP and above including John Deere 6M/6R/7R, New Holland T6/T7, CLAAS Arion 500/600, and Fendt 700/800 Vario series, all of which are widely used on UK arable and livestock farms. The 540 rpm rated input speed matches the standard PTO output speed on all these tractor ranges.

Q: Where can I get a customised agricultural gearbox with a modified mounting flange and non-standard gear ratio for an OEM build project in England or Scotland?

Our factory engineering team handles OEM customisation requests including non-standard gear ratios, modified shaft lengths, altered mounting bolt patterns, and special housing configurations. MOQ starts from 10 units for customised agricultural gearbox variants. Share your drawing or requirement specification with [email protected] and our engineers will review feasibility and provide a formal quotation within 2-3 working days.

Q: When should I change the gearbox oil on an HC-RC130-146 agricultural gearbox used in year-round verge management and silage mowing operations in the UK?

Under typical UK agricultural duty — seasonal grassland management, verge cutting, or silage mowing — the first oil change should be carried out after the initial 50 operational hours to remove run-in wear particles. Thereafter, the recommended interval is every 500 operational hours or annually, whichever comes first. Use ISO VG 460 mineral gear oil. The magnetic drain plug should be cleaned at every service. Operating in very wet or dusty conditions, as encountered on UK farms from October through February, may warrant more frequent inspection of seal integrity.
