Pöörleva lõikuri jõuvõtuvõlli käigukast EP-RC61T | Mitmekäiguline 60 HP

Rotary Cutter PTO Gearbox Overview

The EP-RC61T is a versatile pöördlõikuri jõuülekande käigukast built for brush hog and rotary cutter applications requiring up to 60 HP of PTO input power. What distinguishes this Jõuvõtuvõlli käigukast from single-ratio units is its availability in four gear configurations — 1:1, 1:1.21, 1:1.46, and 1:1.93 — achieved through different tooth count combinations on the spiral bevel gear pair. This allows operators and equipment manufacturers to match the gearbox output speed precisely to their specific cutter head design and vegetation conditions. At 540 RPM input, the four ratio options deliver output speeds ranging from 540 RPM (direct drive) up to approximately 1,042 RPM (at 1:1.93), covering the full range that standard rotary cutters need for grass, brush, and light timber clearing.

See Jõuvõtuvõlli käigukast weighs 33.5 kg — a mid-weight category that reflects the 60 HP power rating and the heavy-gauge cast iron housing required for rotary cutter service. Both input and output shafts use a 1 3/8-inch, 6-spline (Z6) connection, which is the standard PTO interface across virtually all traktori jõuvõtuvõlli käigukast applications in the 30-75 HP range. This standardization means the EP-RC61T can be fitted to a wide variety of rotary cutter brands and Jõuvõtuvõlli käigukast configurations and models with minimal or no modification.

Ratio Selection Guide

Choosing the correct ratio depends on your cutter blade design, target tip speed, and the type of vegetation you cut most frequently. Here is a practical breakdown:

• ➤1:1 (16/16 teeth) — Direct drive. Output matches the 540 RPM PTO input. Best for heavy-duty stump cutting and thick brush where maximum torque at the blade is more important than tip speed.
• ➤1:1.21 (17/14 teeth) — Slight speed increase to ~653 RPM. Good general-purpose ratio for mixed grass and light brush conditions where a small boost in blade speed improves cut quality.
• ➤1:1.46 (19/13 teeth) — Medium increase to ~788 RPM. Popular for dedicated grass and weed cutting rotary cutters where cleaner cuts at higher blade speed are preferred over raw torque.
• ➤1:1.93 (27/14 teeth) — Highest speed at ~1,042 RPM. Designed for light-duty rotary cutters and finish mowers where maximum blade speed produces the smoothest cut surface. Note: this ratio uses a smaller 5.5 module gear versus 7.0 on the other options.

Pasture Rotary Cutting

Standard rotary cutters (brush hogs) on livestock farms use this Jõuvõtuvõlli käigukast to maintain pastures, clear field borders, and manage fallow land. The 1:1.21 or 1:1.46 ratios are most commonly selected for this work, providing the balance of speed and torque needed for mixed grass and light weed conditions on Korean farms.

Roadside and Utility Right-of-Way Clearing

Municipal and utility maintenance crews use heavier rotary cutters with the 1:1 ratio for clearing brush, saplings, and overgrown vegetation along roads, power line corridors, and drainage channels. The 60 HP rating handles the intermittent heavy loads that occur when the blade contacts thick stems or hidden debris.

Orchard and Vineyard Floor Maintenance

Smaller rotary cutters mounted on compact tractors use the 1:1.46 or 1:1.93 ratios for inter-row mowing in orchards and vineyards. The higher blade speed produces a cleaner cut on the grass and cover crops growing between tree or vine rows, reducing the need for additional trimming.

Seotud tooted

Rotary cutters work hard on driveshafts. The intermittent shock loads from blade impacts require a PTO shaft with adequate torque rating, properly functioning slip clutch or shear bolt protection, and a full-length safety guard. Korea Ever-Power supplies matched PTO shafts and a complete range of põllumajanduslikud käigukastid for every type of rotary cutting equipment.
