Cut rough areas without walking behind the mower.

The Farmry RM20 is a remote-controlled track mower built for property owners who need a compact machine for slopes, weeds, ditch edges, fence lines, and rough mowing areas.

Instead of walking directly behind the mower, the operator controls driving, steering, mowing, and speed from a handheld remote. This makes the RM20 especially useful for uneven ground, sloped areas, thick grass, and places where a traditional walk-behind mower is hard to control.

Powered by a 6.1HP EPA-certified gas engine and equipped with a 20.9" cutting deck, the RM20 is a practical fit for rural homes, large yards, small farms, cabins, orchard edges, pond banks, and general property maintenance.

For mowing and normal operation, the RM20 is rated for slopes up to 30°. For travel-only climbing, the tracked undercarriage can handle slopes up to 45° under suitable ground conditions.

Product Features

Effortless Remote Operation

All mower functions are controlled by the operator via a handheld remote. You’ll quickly see how little effort is required. Whether you’re mowing the lawn or tackling weeds on slopes, you can easily complete every task simply by operating the remote.

Stable & Reliable Control Box

This mower is fitted with an in-house developed IC main control board housed within an all-in-one control enclosure that integrates motor drive, engine management and wireless remote control modules. Patents are pending for the relevant technology. All control enclosures undergo aging testing prior to assembly, and prototype units have completed over 20,000 hours of reliability validation. The machine delivers consistent operation and precise control of all mowing functions.

High-Performance EPA-Compliant Engine

Powered by a 6.1HP EPA-certified gas engine, the RM20 provides reliable and environmentally-friendly performance, making it suitable for rigorous mowing tasks.

Optimized Compact Size and Cutting Width

Boasting a 20.9-inch cutting width and compact 38.6" × 38.6" × 19.3" frame, this mower works ideally for small to medium lawns and intricate landscape terrain.

Max. Safe Operating Slope Up to 30°

The machine delivers stable mowing performance on slopes up to 30° under normal operation. Continuous mowing on slopes steeper than 30° creates extreme tilt conditions and poses potential safety hazards to the engine.

Adjustable Cutting Height

Features adjustable cutting height ranging from 1.2" to 4.7", accommodating all grass types and lengths to fit all landscaping requirements.

Self-Charging System

Its self-charging power system replenishes the built-in 24V battery while running for nonstop continuous mowing.

Variable Speed Control

Two travel speed settings of 0.9 mph and 1.6 mph are available. Operators can switch between low and high speed via the remote control joystick based on grass density and slope gradients to optimize mowing performance.

Reliable Safe Travel Module

This remote-controlled mower features a tracked undercarriage that delivers outstanding stability and traction on slopes up to 45°, rough terrain and soft ground. Its travel motor comes with overcurrent protection, which automatically cuts power upon hitting obstacles or encountering excessive loads to safeguard the unit.

Reviews & Questions

Remote-Controlled Track Mower for Slopes and Rough Areas

The Farmry RM20 is a remote controlled slop mower built for grass, weeds, sloped areas, ditch edges, fence lines, and rough property maintenance.

Instead of walking directly behind the mower, the operator complete controls driving, steering, mowing, and speed from a handheld remote at a safe distance while keeping the machine within clear line of sight.

The RM20 is rated for safe mowing and normal operation on slopes up to 30°. For travel-only climbing, the tracked undercarriage can handle slopes up to 45° under suitable ground conditions.

Rubber Track Drive for Better Grip on Uneven Terrain

The RM20 uses a rubber tracked undercarriage to provide better traction than standard wheels on slopes, damp grass, soft ground, and uneven terrain.

This track-drive design helps the remote controlled track mower stay more stable across rough property areas such as ditch edges, pond banks, orchard edges, fence lines, and uneven yards.

For best results, mow across slopes whenever possible instead of driving straight uphill or downhill. Avoid operating on loose, wet, slippery, or unstable ground where the machine may slide or lose traction.

Compact 20.9" Cutting Deck with Gas-Powered Performance

Powered by a 6.1HP EPA-certified gas engine, the RM20 is designed for practical mowing work around rural homes, large yards, cabins, small farms, and maintenance properties.

The 20.9" cutting width gives it a compact footprint for narrow strips, tight turns, property edges, and areas where larger machines may be difficult to maneuver.

The RM20 has two travel speeds: 0.9 mph low speed and 1.8 mph high speed. Use low speed for dense grass, tall grass, slopes, and tighter control, and high speed for easier travel across open areas.

FAQs

Can remote-controlled mowers cut wet grass?

The tracked undercarriage provides better traction than standard wheels on damp grass and uneven ground. However, avoid mowing during heavy rain, standing water, deep mud, or conditions where wet debris may clog the cutting deck. For best cutting performance, mow when grass is dry or only lightly damp.

What regular maintenance does this remote mower need?

Regular maintenance includes checking engine oil, cleaning the cutting deck and undercarriage, inspecting blades, checking track tension, removing built-up grass or debris, and inspecting belts, fasteners, and wear parts. Always follow the maintenance schedule in the operator’s manual.

Is this one of the rc mowers that works on uneven terrain?

Yes—its crawler track system is built for uneven terrain, wet grass, and uneven surfaces where wheels can slip.

How well do RM20&RM20S work on steep slopes?

The RM20 and RM20S are rated for safe mowing and normal operation on slopes up to 30°. The tracked undercarriage can support travel-only climbing up to 45° under suitable ground conditions. For best results, mow across the slope instead of straight up and down, and avoid operating on loose, wet, or unstable ground.

What is the cutting width and deck construction?

The cutting width is 20.9", and the mowing deck is 4 mm thick and reinforced for durability in tough jobs.

How fast is the mower during mowing and travel?

Blade tip speed: up to 111 m/s.
Travel speed: up to 1.8 mph (3 km/h), enabling efficient movement between work sites.

What engine power does the RM20 use?

It uses a 6.1 HP / 4.5 kW engine at 2000–4000 RPM, compliant with Euro 5 + EPA, delivering dependable power for slope work.
