Beskrivelse
HC-RTM130 Rotary Tiller Gearbox
Heavy-duty rotary tiller gearbox engineered for demanding UK and European arable farming conditions — delivering consistent power transmission at 540 r.p.m. PTO input with a compact, field-proven drivetrain.
The HC-RTM130 rotary tiller gearbox sits at the heart of professional tillage equipment across the UK, replacing worn units on established brands and powering bespoke OEM machines built for British soil conditions. With a gear ratio of 1:1.46 and rated input speed of 540 r.p.m., this agricultural gearbox translates tractor PTO power cleanly into reliable rotary blade drive — with none of the vibration spikes that prematurely fatigue lighter-grade housings.
Fitted within the RTM series alongside its siblings — the RTM 105, 120, 135, 150, and 165 — the RTM130 targets the mid-range working width sweet spot preferred by mixed arable and vegetable-growing operations. It handles 33 kW (45 HP) of continuous input power and a total unit weight of 31 kg, keeping the front end of the rotary tiller balanced and reducing wear on tractor linkage pins.
Agricultural machinery dealers, spare-parts distributors, and integrators across England, Scotland, and Wales have sourced this gearbox directly from our manufacturing facility. Custom shaft configurations, flange adaptations, and OEM paint finishes are available on request.

How It Works, What It’s Made From, and Where It’s Used
Arbejdsprincip
The HC-RTM130 operates as a right-angle bevel gear drive. The tractor’s PTO shaft delivers rotational input at 540 r.p.m. through a universal-joint stub shaft, transferring torque to the primary bevel pinion. The meshing bevel ring gear — cut to a 1:1.46 ratio — steps up output RPM to the rotor shaft, spinning the tiller blades at the speed needed to break compacted soil effectively. The sealed housing maintains a stable lubricant film across the gear faces under continuous operation, preventing heat build-up during extended field passes. An integrated overload protection sleeve can be factory-fitted on request, shielding the drivetrain when blades encounter buried stone or root obstructions — a common challenge in UK clay and chalk farmland. The gearbox mounts directly onto the rotary tiller chassis frame using a standardised flange pattern, making it compatible with a wide range of European OEM tiller frames without modification.
Materials & Construction
The main housing is cast from high-grade grey iron, chosen for its vibration-damping properties and resistance to the impact loads that rotary tillage generates on every headland turn. Internal bevel gears are machined from case-hardened alloy steel — typically 20CrMnTi — carburised to a surface hardness of HRC 58–62 for extended tooth life. Bearings are deep-groove ball or tapered roller types depending on load direction, press-fitted to precision h6/H7 bore tolerances. All rotating seal positions use double-lip rubber oil seals with a garter spring, rated for continuous mud and water exposure in line with the harsh ground-level conditions of British tilling operations. The exterior receives a two-coat primer and gloss enamel finish, and can be matched to customer RAL colours for OEM fleets. Every unit leaves our facility having passed a no-load running test and a visual sealing inspection before dispatch.
Applikationsscenarier
The HC-RTM130 agricultural gearbox is well matched to rotary tillers operating on medium to large arable plots in England and Scotland, where working widths between 1.3 m and 1.6 m are common. It suits vegetable-bed preparation on market gardens in East Anglia, primary and secondary cultivation on cereal farms across the East Midlands, and seedbed finishing ahead of oilseed rape drilling in Yorkshire. Contractors and hire-fleet operators running multi-shift tillage programmes favour it for its tolerance of high daily duty cycles. The gearbox also sees use in orchard floor management, where a compact footprint and low-vibration output protect tree root zones. Beyond the UK, export customers in Ireland, the Netherlands, and Northern France specify it for similar medium-horsepower tractor pairings — particularly with 60–80 HP tractors common in those markets.

Manufacturing Facility & Custom Engineering Services
Our production facility covers over 35,000 square metres of dedicated machining, gear-cutting, heat-treatment, and assembly floor space. CNC hobbing machines hold gear tooth profile tolerances to DIN quality grade 7 or better, and our gear-grinding centre provides the surface finish quality demanded by OEM customers who need quiet-running drivetrains for enclosed cab tractors. Every HC-RTM series gearbox is assembled in a clean-room partition separate from raw casting operations, ensuring no swarf contamination reaches the finished bearing seats or oil galleries.
Customisation is a core part of what we do — not an afterthought. UK machinery manufacturers and integrators frequently need agricultural gearboxes adapted beyond catalogue specification: non-standard PTO stub shafts, modified output flange bolt circles, alternative oil viscosity specifications for cold British winters, and branding with customer part numbers. Our engineering team works from customer-supplied drawings or 3D step files and can produce first-off samples within four to six weeks from confirmed design freeze. Minimum order quantities on standard models are low, and custom-configuration batches are discussed case by case to suit the customer’s production schedule.

Kundens succeshistorie
Greenfield Agri Solutions builds compact rotary tillers for the UK horticultural market — units designed to fit between raised beds on market gardens and in polytunnel runs where clearance is limited. Their previous gearbox supplier was unable to hold flange tolerances consistently, resulting in misalignment vibration that damaged tiller-frame welds after one or two seasons. After switching to the HC-RTM130 agricultural gearbox in 2023, Greenfield ran 14 units through an 18-month field trial covering Lincolnshire vegetable operations and Cambridgeshire flower farms.
The trial recorded zero in-field gearbox failures. Post-season strip-down inspections showed normal gear tooth wear within expected limits. Greenfield subsequently placed a standing order for 60 units annually, with three non-standard shaft options to suit their full product range. The ability to supply OEM-branded units with Greenfield’s own part numbers was cited as a deciding factor in choosing to consolidate supply with a single gearbox partner.
“We’ve been sourcing rotary tiller gearboxes for our repair workshop in Norfolk for four years. The RTM130 fits straight onto the old Italian tiller frames we see most often here — no adaptor plates, no shimming. Lead time on repeat orders is consistently two to three weeks to our yard.”
“We ordered a batch of 25 units with a custom output shaft diameter for our compact tractor-mounted tillers. The engineering team turned around a confirmed drawing in three days and first samples arrived on time. Quality of the castings and machining is noticeably better than units we had previously sourced from elsewhere.”
“Running four tillage contractors across Scotland and we’ve standardised on this gearbox as our preferred replacement unit. The sealed construction handles the wet and muddy conditions up here far better than anything we tried before. Pricing is very competitive for the quality you get.”

A gear ratio of 1:1.46, as fitted in the HC-RTM130 series, is the standard specification for 540 r.p.m. PTO-driven rotary tillers used in vegetable-bed preparation. This ratio steps up the output speed to deliver the blade tip speed required for fine seedbed finish on market-garden soils typical in East Anglia and the East Midlands.

As a general guideline, drain and replace the gear oil after the first 50 operating hours to flush running-in wear debris, then every 200–250 hours thereafter. Use the specified EP90 or EP80W-90 gear oil. If the oil appears milky or smells burnt, change it immediately — this may indicate seal wear or overheating requiring further inspection.
+
Yes. The HC-RTM130 agricultural gearbox is well suited to orchard floor management tillers. Its compact overall length and low-vibration output protect tree root zones during inter-row cultivation. Scottish orchard and soft-fruit farm operations have used this gearbox successfully across wet, clay-heavy soils where seal integrity is particularly important.
