Not every farm needs a 100+ HP gearbox. The RC-30 is the entry point of the Omni Gear replacement range — a 40 HP rotary cutter PTO gearbox offered in three ratio options (1:1.47, 1:1.71, and 1:1.93) to match different blade designs and vegetation types. This gives small-to-medium operators the flexibility to select the exact output speed for their cutting conditions rather than being locked into a single ratio. At 540 RPM input, the three options deliver 793, 923, or 1,042 RPM respectively. The unit also accepts 1,000 RPM PTO input for tractors equipped with the higher-speed option.

The RC-30 shares the same weight class (51 lbs / 23.1 kg) and 4-bolt mounting pattern (4-3/4 inch) as the RC-33, but offers the additional ratio choices and uses triple lip spring-loaded seals for improved dust exclusion — a meaningful upgrade for operators working in sandy or dusty soil conditions where seal failure is a common cause of premature редуктор ВОМ failure. Deep groove ball bearings handle the combined radial and axial loads from the bevel gear mesh.

Choosing Your Ratio

The RC-30's three ratio options let you tune the gearbox to your primary cutting conditions:

Rotary cutter pto gearbox rc30 product-1

  • 1:1.47 → 793 RPM output. Lowest speed, highest torque at the blade. Ideal for thick brush, weeds, and light saplings where cutting force matters more than blade speed. The default choice for most Korean small-farm rotary cutters.
  • 1:1.71 → 923 RPM output. Middle ground for mixed conditions — grass plus occasional brush patches. A good all-rounder when vegetation types vary across the cutting area.
  • 1:1.93 → 1,042 RPM output. Highest speed for grass-dominant cutting where a clean, mulching-quality finish is the priority. Produces finer chopping of cut material but has less torque reserve for heavy brush.

Seal and Bearing Design

The RC-30 uses triple lip spring-loaded shaft seals on both input and output — an upgrade over the single or double lip seals on some competing редуктор ВОМ units. Each lip provides a separate barrier against dust, moisture, and debris ingress, while the spring maintains positive contact pressure as the seal wears. This matters on Korean farms where sandy soil in coastal areas and fine dust in inland regions are persistent threats to редуктор ВОМ longevity. The deep groove ball bearings are selected for their ability to handle the combined radial and axial forces from the bevel gear mesh at the 40 HP power level, with adequate load margins for the intermittent shock loads from blade-to-obstacle contact.

Typical Applications

The RC-30 is designed for 4-foot and 5-foot rotary cutters on 25-40 HP compact and utility tractors. In Korea, this covers the majority of small-scale livestock farms, vegetable operations, orchard perimeters, and rural property maintenance. The compact 10-1/4 x 7 x 7 inch size fits standard cutter deck редуктор ВОМ housings without modification, and the 4-bolt mounting on 4-3/4 inch centers matches the most common domestic and imported cutter brands.

Small Livestock Farms

Korean cattle, goat, and poultry farms with 2-10 hectares of pasture are the primary market for the RC-30. These operations typically own a single 25-40 HP compact tractor that serves multiple duties — tilling, mowing, hauling, and spreading. The RC-30 turns the rotary cutter into a productive attachment on that same tractor, handling seasonal pasture maintenance, fence line clearing, and weed control around buildings and pens.

Rural Property and Orchard Maintenance

Property owners managing rural land — weekend farms, orchard perimeters, unused field margins — use small rotary cutters for periodic vegetation control. The triple lip seal design on this редуктор ВОМ is particularly valuable for operators who use the cutter infrequently, as the seals maintain their integrity during storage periods when other seal types may dry out and crack.

Companion Products and Service

PTO shaft and gearbox companion

A rotary cutter is only as reliable as the weakest link in the drivetrain. Even at the 40 HP level, a worn or incorrectly sized PTO driveshaft can introduce vibration that accelerates gearbox bearing wear. Korea Ever-Power supplies matched PTO shaft assemblies for every power class from 15 to 200 HP. We also carry the complete RC gearbox series (RC-30, RC-33, RC-51, RC-61T, RC-145) and over 400 other сельскохозяйственная коробка передач replacement models. ISO 9001-certified production with individual bench testing, 12-month warranty covering materials and workmanship, and Korea warehouse dispatch with 2-4 day delivery nationwide. Volume discounts are available for agricultural cooperatives and equipment dealers ordering multiple units across different ratio options.

Quality and Warranty

Every RC-30 редуктор ВОМ is manufactured under ISO 9001:2015-certified quality controls. Individual bench testing verifies gear noise, seal integrity, and dimensional accuracy before dispatch. The triple lip seal design is validated for 2,000+ hours of service life under standard agricultural dust conditions. Korea Ever-Power provides a 12-month warranty covering materials and manufacturing defects, with replacement seals, bearings, and gasket kits stocked at our Korea warehouse for immediate dispatch. Our technical support team helps with cross-referencing, shaft verification, and ratio selection — contact us before ordering if you are unsure which ratio suits your cutting conditions.

Questions and Answers

Which ratio should I order for general pasture mowing?
For mixed grass and light brush, the 1:1.47 is the standard choice. If your pasture is mostly clean grass with minimal brush, the 1:1.71 or 1:1.93 gives a finer cut finish.
Does the RC-30 fit a 50 HP tractor?
The gearbox is rated at 40 HP maximum. Running 50 HP at full PTO load risks overloading the gears. Step up to the RC-33 (65 HP) for larger tractors.
What is a shear bolt hole for?
The 1/2-inch shear bolt hole accepts a sacrificial bolt that breaks under severe impact (blade hitting a large rock or stump), protecting the more expensive gears and bearings inside the gearbox from damage.
Where can I buy the RC-30?
All three ratio options are stocked at our Korea warehouse. Browse all models at our PTO gearbox catalogue.

Customer Feedback

Lee Won-seok, Small Dairy Farm, Chungcheongbuk-do (spring 2025)
"Perfect size for my 35 HP Kukje and 4-foot cutter. Ordered the 1:1.47 ratio. Handles our pasture well — even the thistle patches near the fence line. About 120 hours, no issues."
Oh Hye-jin, Orchard Maintenance, Gyeongsangnam-do (autumn 2024)
"Got the 1:1.93 ratio for clean grass cutting between pear tree rows. The faster blade speed really does give a noticeably better finish. The triple lip seals are a nice touch — our old gearbox leaked from dust getting past the seals."
Han Dong-wook, Equipment Dealer, Gwangju (early 2025)
"The RC-30 is my volume seller. Having 3 ratio options from one model line simplifies stocking and ordering. Consistent quality, fast delivery. No complaints from customers."
