\n

What Is the HC30 Rotary Agricultural Gearbox?<\/h2>\n

\"Rotary\"The HC30 Rotary agricultural gearbox is a purpose-engineered power transmission component designed for rotary cultivators, rotavators, and soil preparation equipment operating across the UK’s diverse farmland. Rated at 30 HP with a 1:2.9 gear ratio and a standard 540 RPM PTO input, the HC30 delivers dependable torque multiplication for medium-duty tillage tasks \u2014 whether you’re working light sandy loam in East Anglia or heavier clay soils in the Midlands. With a net weight of 13.5 kg, the gearbox balances robustness and practical handling, making mounting and seasonal removal a straightforward task for farm workshops of any size. The module-3.0 gear tooth profile and 32\/11 tooth combination are precision-engineered to sustain continuous operation under varying soil resistance loads, reducing the risk of premature wear that commonly affects lower-specification gearboxes used in demanding British field conditions. Whether you are equipping a compact tractor or a mid-range agricultural machine, the HC30 offers a proven mechanical foundation that supports season-long reliability with minimal maintenance intervention.<\/p>\n<\/div>\n

The HC30 receives rotational power from the tractor’s 540 RPM PTO shaft via a 1 3\/8 Z6 splined input connection. The internal bevel or helical gear set \u2014 with a 32-tooth driven gear meshing against an 11-tooth drive pinion \u2014 steps down input speed while multiplying output torque at a 1:2.9 ratio. This increased torque is delivered through the optic axis output to drive rotary tines or blades, ensuring consistent soil penetration depth even as ground resistance fluctuates across field sections. The gear meshing action is lubricated by a sealed oil bath, maintaining film thickness across the tooth contact zone under sustained field operation.<\/p>\n<\/div>\n

\n

Construction & Materials<\/h3>\n

The outer casing is formed from high-grade cast iron, chosen for its vibration-damping properties and resistance to impact damage from soil stones \u2014 a genuine concern on stony upland farms across Yorkshire, Devon, and the Scottish Borders. Internal gears are manufactured from alloy steel with case-hardened tooth flanks, achieving surface hardness levels that sustain contact fatigue life across many thousands of hectares of cultivation. Input and output shaft bearings are heavy-duty tapered roller or deep-groove ball bearings retained by precision-machined housings. All external seals use lip seal technology rated for field mud, crop debris, and prolonged wet exposure.<\/p>\n<\/div>\n

\n

Typical Field Applications<\/h3>\n

In the UK market, the HC30 rotary agricultural gearbox is most commonly specified for rotary cultivators working spring seedbed preparation on arable farms, power harrows used in vegetable-growing operations across Lincolnshire and East Yorkshire, rotavator attachments on mixed livestock and arable holdings, and compact orchard cultivation machines used by soft fruit growers in Kent and Worcestershire. Its 30 HP rating also suits paddock maintenance rotavators and amenity groundscare machinery operated by local councils, estate managers, and equestrian facilities throughout England, Scotland and Wales.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

Arable Cultivation \u00b7 420-hectare Farm \u00b7 Spring Barley & Oilseed Rape<\/p>\n<\/div>\n<\/div>\n

GreenHill Arable replaced their worn original-fit rotary cultivator gearbox ahead of the 2024 spring drilling campaign. Their farm engineer contacted us seeking a direct-fit replacement compatible with their 35 HP compact tractor’s PTO. After confirming the 540 RPM input and 1 3\/8 Z6 spline specification, two HC30 units were supplied within ten working days. Both gearboxes were installed without modification and ran for the full spring cultivation period \u2014 approximately 180 hectares per unit \u2014 without any oil sealing issues or overheating. The farm manager noted a marked reduction in vibration compared to their previous aftermarket replacement, attributing this to the more precise gear module specification of the HC30.<\/p>\n

Common questions from UK buyers and agricultural machinery professionals<\/p>\n

\n
\n
\nWhat is the price of an HC30 rotary agricultural gearbox and can I get a quote for bulk supply to a UK farm machinery dealer?<\/summary>\n
\n

Pricing for the HC30 rotary agricultural gearbox depends on order quantity, any custom specification requirements, and current shipping routes to your UK location. We supply both single units for replacement orders and larger batches for machinery dealers and OEM manufacturers. To receive an accurate, no-obligation quote for supply to a UK dealership or farm equipment business, please contact us directly at sales@pto-drive-shafts.com<\/a> with your required quantities and any specification notes. We typically respond within one business day.<\/p>\n<\/div>\n<\/details>\n<\/div>\n

\n
\nWhich UK tractor brands and PTO specifications is the HC30 agricultural gearbox compatible with?<\/summary>\n
\n

The HC30 uses a standard 1 3\/8 Z6 splined input shaft running at 540 RPM, which is the most widely used PTO configuration on UK farm tractors including those from John Deere, New Holland, Massey Ferguson, Case IH, Claas, and Kubota in the 25\u201350 HP class. As long as your tractor’s PTO output matches this specification \u2014 which covers the vast majority of machines registered under DVSA agricultural categories in the UK \u2014 the HC30 will connect directly without modification. If your machine uses a different spline count or shaft diameter, we can supply a modified input shaft configuration; contact us with your tractor model details.<\/p>\n<\/div>\n<\/details>\n<\/div>\n

\n
\nHow long does delivery take when ordering an HC30 rotary gearbox to a farm or agricultural supplier in England, Scotland, or Wales?<\/summary>\n
\n

Standard lead time for HC30 rotary agricultural gearbox orders is typically 15 to 25 working days from order confirmation, which covers production, quality inspection, and international freight to UK port. Urgent replacement orders ahead of cultivation seasons can often be accommodated on an expedited basis \u2014 please flag your required date when you enquire. We ship to all UK mainland addresses including rural locations in Scotland, Wales, and Northern England, and our freight partners are experienced with agricultural consignments of this type. Pallet and courier delivery options are both available depending on quantity.<\/p>\n<\/div>\n<\/details>\n<\/div>\n

\n
\nCan I use the HC30 gearbox on heavy clay soils like those found across the East Midlands or Vale of York arable farmland?<\/summary>\n
\n

Yes. The HC30 is designed to sustain continuous operation under the elevated torque loads characteristic of heavy or compacted soils. Its 30 HP rating, module-3.0 gear profile, and alloy steel internal gears provide adequate fatigue life for clay soil conditions where rotary tine resistance is significantly higher than on lighter sandy loams. The sealed cast iron housing also performs well in wet, sticky soil environments by resisting contamination entry. That said, as with any gearbox used in demanding conditions, correct oil level maintenance and seasonal inspection of lip seals is recommended to maximise working life.<\/p>\n<\/div>\n<\/details>\n<\/div>\n

\n
\nWhere can I find a reliable supplier of HC30 rotary agricultural gearboxes for OEM integration into rotavator equipment manufactured in the UK?<\/summary>\n
\n

agriculturalgearboxes.top supplies HC30 rotary agricultural gearboxes directly to UK-based OEM rotavator and cultivation equipment manufacturers. Our factory offers drawing-to-sample prototyping, custom spline and output shaft configurations, and private-label packaging suitable for your branded product range. We work with engineering teams to validate dimensional fit before production commences, which is particularly important for OEM integrations where replacement serviceability in the field depends on consistent dimensional accuracy across supply batches. Contact sales@pto-drive-shafts.com<\/a> to discuss your OEM requirements.<\/p>\n<\/div>\n<\/details>\n<\/div>\n

\n
\nWhat gear oil type and maintenance schedule does the HC30 rotary gearbox require for use on UK vegetable and arable farms?<\/summary>\n
\n

The HC30 rotary agricultural gearbox is filled with gear oil at the factory for initial run-in and delivery. For field operation, the gearbox uses an EP (extreme pressure) gear oil rated GL-4 or GL-5 at the viscosity grade specified in the supplied documentation \u2014 typically SAE 80W-90 for temperate UK operating temperatures. Oil level should be checked before each season and at mid-season if the gearbox is in continuous daily use on vegetable or arable cultivation work. A full oil change is recommended every 200\u2013300 operating hours or annually, whichever comes first. Lip seal condition should be inspected at each service interval, particularly after operations in very wet or abrasive soil conditions.<\/p>\n<\/div>\n<\/details>\n<\/div>\n<\/div>\n<\/div>\n
