HC-RC30-193 PTO Gearbox

The HC-RC30-193 is a right-angle, bevel-gear PTO gearbox purpose-built as a compact speed increaser. When a standard tractor PTO outputs 540 rpm through the 1 3/8 inch, 6-spline (Z6) input shaft, the gearbox multiplies that rotational speed by a factor of 1.93, delivering approximately 1,042 rpm at the output optical axis. This is particularly valuable for driven equipment that demands a higher operating speed than the tractor PTO natively provides — such as hydraulic generators, rotary brushcutters, water pumps, and light industrial machinery installations across agricultural estates in England, Scotland, Wales, and Northern Ireland.

The unit handles a continuous power rating of 30 HP, giving it a comfortable safety margin when paired with tractors in the 25–50 HP bracket that form the backbone of UK smallholding and arable operations. Its compact bevel-gear architecture means the 90-degree shaft change is achieved within a lightweight 24.5 kg housing — low enough to be easily serviced in the field without specialist lifting equipment.

Precision Bevel Gear Pair

The 15/29 tooth bevel gear set is cut to Module 4.0 standard, delivering smooth power transfer with minimal backlash. Each gear is case-hardened and precision-ground to ensure long service life even under the shock loads common on UK farm tracks and seasonal harvesting conditions.

Universal PTO Compatibility

The standard 1 3/8 inch, 6-spline input shaft (ISO 500) slots directly into virtually every agricultural tractor sold in the United Kingdom — from compact utility tractors to mid-range row-crop machines — without adaptors or custom machining. This plug-and-work design significantly reduces installation time on farm.

30 HP Continuous Rating

Rated at 30 HP for sustained operation, the HC-RC30-193 is not a peak-only figure — it reflects real-world continuous duty. British machinery dealers and OEM integrators frequently note that competing products derate significantly after 30 minutes of operation. This unit maintains output through full-day harvest cycles without thermal shutdown.

Field-Serviceable Housing

At 24.5 kg, the cast-iron housing is robust enough for hard agricultural use yet light enough for one engineer to handle without a hoist. The split-housing design allows bearing replacement and gear inspection without removing the unit from the machine frame, cutting servicing costs significantly for UK-based agricultural contractors.

The housing of the HC-RC30-193 is manufactured from high-grade grey cast iron (GG25 equivalent), chosen for its outstanding vibration-damping properties and resistance to oil seepage over extended service intervals. Internal gear bores are machined with tight tolerances to ensure the bevel gear pair runs true even as operating temperatures fluctuate between cold UK winter mornings and summer peak harvesting days.

The bevel gears themselves are forged from 20CrMnTi alloy steel — a low-alloy, case-hardening steel common in high-load transmission applications. After rough machining, each gear blank undergoes carburising heat treatment to achieve a surface hardness of 58–62 HRC on the tooth flanks, while the core retains toughness above 35 HRC. This dual-zone hardness profile resists both pitting fatigue at the tooth surface and fracture at the gear root — the two failure modes most frequently encountered in field-operated PTO gearboxes.

Internally, taper roller bearings support the input and output shafts, selected for their ability to handle combined radial and axial loads simultaneously — a requirement dictated by the 90-degree power-flow change inherent in right-angle gearbox design. An oil-bath lubrication system ensures every bearing and gear tooth surface receives continuous lubrication during operation, and the oil capacity is sized to eliminate the need for external oil cooling even at the full 30 HP rated load.

PTO Generators

When connecting a 50 Hz alternator that requires ~1,000 rpm or greater, the HC-RC30-193 bridges the speed gap from the standard 540 rpm PTO output.

“We’ve been running two of these units on our PTO generator sets for three seasons without a single issue. The output speed is exactly what we need to hold 50 Hz under load. Solid build quality, and the price was very competitive compared to European alternatives.”

★★★★★

“Ordered a batch of six for our OEM brushcutter production line. The HC-RC30-193 fit our existing driveline geometry perfectly. Lead time was acceptable and the technical data sheet was clear enough for our draughtsmen to design around. We’ll be placing repeat orders.”

★★★★★

“Used on a tractor-driven centrifugal pump for our irrigation scheme in East Anglia. The 1:1.93 ratio gives us just the right pump shaft speed. The unit runs cool even during long pumping sessions in summer. Delivery was fast, and sales were responsive to a technical query we had about shaft length.”

Behind the HC-RC30-193 is a vertically integrated manufacturing facility operating under ISO 9001 quality management. Our CNC gear-cutting centres, heat-treatment lines, and CMM inspection cells are all in-house — giving us direct control over quality at every stage from raw billet to finished gearbox. This makes it practical to offer OEM customers and machinery builders genuinely customised configurations without the minimum-order constraints or lead-time penalties that typically accompany custom gear products.

Common custom requests from UK buyers include modified input shaft lengths, alternative output flange patterns, non-standard gear ratios within the same housing envelope, dual-output configurations for splitting power to two driven shafts, and special surface treatments for corrosive environments such as coastal locations or chemical spray equipment. Our engineering team can evaluate a custom enquiry and return a preliminary design confirmation within three to five working days.

We supply both individual replacement units for farm and workshop use and batch orders to OEM integrators. UK buyers benefit from competitive ex-works pricing, with established freight partners offering door-to-door delivery across England, Scotland, Wales, and Northern Ireland, typically within 12–18 working days for standard stock models.

With a 540 rpm input — which is the standard low-speed PTO setting on the vast majority of agricultural tractors used in the United Kingdom — the HC-RC30-193 delivers an approximate output speed of 1,042 rpm. This is calculated by multiplying 540 rpm by the gear ratio of 1.93. This output speed is well-suited to applications such as PTO-driven alternators, small centrifugal pumps, and rotary cutting heads that require shaft speeds above the native PTO output.

In the UK, right-angle PTO speed increaser gearboxes are most heavily used in arable farming (irrigation pumps, spreaders), livestock operations (slurry agitators, feeders), plant hire and groundworks (tractor-driven generators and compressors), horticulture (misting systems, rotary cutters), and custom agricultural OEM machinery manufacturing — particularly in counties such as Lincolnshire, Yorkshire, Shropshire, and East Anglia where large-scale mixed farming operations are concentrated.

The HC-RC30-193 uses an oil-bath lubrication system. The primary maintenance requirement is to check and maintain the gear oil level at the correct fill mark before each season of use, and to carry out a full oil change after the first 50 operating hours (to flush any initial metal particles from the gear bedding-in period), and then every 500 operating hours thereafter. The oil seals should be inspected annually and replaced if leakage is detected. In a typical UK farm environment, with proper oil maintenance, the expected service life is in excess of five years under continuous seasonal use.
