EP-30 Rotavator Gearbox — 30HP Rotary Tiller Gearbox for Agricultural Machinery
Model: EP30 | Input: 540 RPM | Ratio: 1:2.9 | Weight: 13.5 kg
The EP-30 Rotavator Gearbox is a purpose-built farm implement gearbox designed to transfer and multiply torque from a tractor’s PTO shaft to the blade shaft of a rotary tiller. Running at a standard 540 RPM input and stepping up to an effective output via a 1:2.9 gear ratio, it ensures the tiller blades receive the rotational speed needed to break, turn, and pulverise soil in a single pass — reducing tillage time by up to 40% compared to conventional disc ploughing.
Rated at 30 HP continuous power, the EP-30 is compatible with compact and mid-range tractors widely used across paddy field preparation, dry land cultivation, orchard management, and seedbed finishing. The 1 3/8″ Z6 spline input shaft is an industry-standard interface, making retrofit installation straightforward on most existing rotavator frames without custom adaptation.

Features of the EP-30 Rotavator Gearbox
Module-3.0 Helical-Cut Gears
A module of 3.0 with a 32/11 tooth pairing delivers a consistent 1:2.9 output ratio. Helical-profile teeth reduce contact stress and operating noise by approximately 6 dB compared to straight-cut alternatives, extending service life under continuous field loads.
Standard 1 3/8″ Z6 Spline Shaft
The ISO/ASAE S201 compliant 6-spline input shaft fits directly onto category-1 PTO shafts used by 20–40 HP tractors worldwide. No adapters or custom machining are needed, cutting installation time to under 30 minutes.
Cast-Iron Housing with Oil-Bath Lubrication
The high-tensile cast-iron casing resists deformation under peak shock loads — common when tiller blades strike stones or hardpan layers. A sealed oil-bath system maintains consistent lubrication at operating temperatures up to 90°C, with no grease nipples to service in the field.
30 HP Continuous Rated Power
Rated for 30 HP (22 kW) continuous operation — not peak rating — meaning the gearbox handles prolonged heavy-soil passes without thermal runaway. This high torque rotavator gearbox for soil cultivation maintains rated output through full working shifts in clay-heavy fields.
Compact 13.5 kg Assembly
At only 13.5 kg net, the EP-30 adds minimal dead weight to the implement, preserving more of the tractor’s rear hydraulic lift capacity for larger blade widths or heavier frames — a practical advantage on slopes and underpowered equipment.
CE-Certified & 100% Factory-Tested
Every EP-30 unit clears a full load and no-load run test before shipping. CE certification covers mechanical safety and material compliance. A test report specific to your batch is included with every shipment.
Advantages of Heavy-Duty Agricultural Gearboxes vs. Standard Units
Not all farm implement gearboxes are built to the same load specification. Here is why upgrading to a heavy-duty rated unit like the EP-30 matters in real-world field conditions:
- Longer blade-shaft service life: Gear tooth contact stress is directly proportional to module size. The M3.0 specification distributes load across a wider face width, reducing pitting fatigue by 25–35% under equivalent input torque compared to M2.5 economy units.
- Lower downtime cost per season: A single unplanned gearbox failure during planting or harvest windows can cost more in lost productivity than the price difference between economy and heavy-duty grades. The EP-30’s sealed housing eliminates the most common failure mode — contaminated lubricant — entirely.
- Wider tractor compatibility: The standardised 540 RPM input and Z6 spline shaft mean one spare unit covers multiple tractors in a mixed fleet, reducing inventory holding costs for dealers and larger farming operations.
- Consistent soil tilth depth: Gear backlash in worn-out economy gearboxes causes blade-speed fluctuation, producing uneven tillage depth. The EP-30’s precision gear mesh (±0.05 mm tooth spacing tolerance) maintains blade-tip speed within ±2% at rated RPM, delivering a uniform seedbed finish pass after pass.
- Reduced operator fatigue: Lower operating noise (helical vs. spur gears) translates directly to a quieter cab environment over long working shifts — measurable with a sound level meter, not just a marketing claim.
Applications of Rotary Tiller Gearboxes in Agriculture
The EP-30 rotary tiller gearbox is used wherever a PTO-driven rotavator or tiller implements are deployed. Typical use cases include:
Puddling and levelling waterlogged fields before transplanting. High torque output handles the resistance of saturated soils without stalling at 540 RPM.
Primary and secondary tillage for corn, soybean, wheat, and vegetable fields. The 30 HP rating covers working widths up to 1.8 m in medium-textured soils.
Weed incorporation, mulch mixing, and inter-row cultivation under fruit trees and vines. Compact 13.5 kg weight keeps implement balance neutral on sloped ground.
Fine tilth preparation for transplanted vegetables and direct-seeded crops. The high torque rotavator gearbox for soil cultivation ensures blade depth consistency to within ±15 mm.
Direct replacement or new-build supply for tiller and cultivator manufacturers sourcing standardised gearbox assemblies. Consistent batch quality verified by pre-shipment test report.
