YM-550 Commercial Brushless Electric Remote Control Slope Mower (48V Lithium)

YM-550 Brushless Electric Slope Mower: Commercial Power Without the Engine

The HONGTAI YM-550 Brushless Electric Slope Mower is built for contractors and asset owners who need heavy-duty slope mowing without the noise, fumes and engine servicing of a gasoline machine. A 48V lithium-ion battery powers dual 500W brushless track motors and a 2,000W brushless cutting motor, giving commercial-grade climbing torque and cutting speed on inclines of up to 45°.

It is designed for steep embankments, orchards, solar power plants and municipal green spaces, and is supplied factory direct to equipment dealers, landscaping contractors, solar O&M companies and municipal buyers across North America and Europe.

Dual Brushless Motors: Maintenance-Free Commercial Drive

Every motor on the YM-550 Brushless Electric is brushless, which matters on a machine that works long hours on demanding ground.

• 2 × 48V 500W brushless track drive motors (75 r/min): each track is driven independently, giving high, steady low-speed torque for climbing and precise 360° zero-turn steering.
• 2,000W brushless cutting motor (4,000 r/min): holds blade speed in dense grass and weeds for a clean, consistent cut.
• No carbon brushes to replace: brushless motors switch current electronically, so there are no brushes to wear out, no carbon dust and no brush sparking.
• Cooler, more efficient running: less friction means less heat and more of the battery’s energy going into mowing.

Combined with an engine-free powertrain, the result is a drivetrain with very little routine maintenance: no oil changes, spark plugs, air filters, fuel filters or brush replacements.

Zero-Emission, Quiet Operation

The YM-550 Brushless Electric runs entirely on a 48V 40Ah lithium battery pack (about 1.92 kWh). An optional 48V 67Ah pack (about 3.2 kWh) extends working time on large sites. Each charge delivers 2 – 3 hours of mowing, depending on grass density and slope.

• Zero exhaust on site: safe to use near homes, schools, clubhouses, water sources and organic crops.
• No fuel handling: no gasoline storage, no refueling on slopes and no spill risk around ponds, reservoirs or solar arrays.
• Quiet working: without a combustion engine, the machine is far quieter than a gasoline mower, so crews can work early, late or in noise-sensitive areas such as parks, estates and hospital grounds.

45° Slope Stability and Anti-Rollover Design

Low Center of Gravity

The chassis stands only 460 mm (18.1 in) tall, and the heavy battery pack sits low in the frame. Industrial rubber tracks spread the 160 kg (353 lbs) machine weight across a wide footprint, so the mower stays planted across the slope instead of sliding or tipping. The YM-550 Brushless Electric is rated for working slopes of 40° to 45°, depending on ground conditions.

Operator Off the Slope

A wireless remote control handles start/stop and steering from up to 200 m (656 ft) away. The operator stands on stable ground with a clear view of the work area, with no rider exposed to rollover and no one walking on wet or loose banks.

Controlled, Steady Travel

Travel speed is adjustable from 0 to 3 km/h (0 – 1.9 mph), giving fine control on steep or uneven ground. Cutting height adjusts electrically from the remote between 20 mm and 70 mm (0.8 – 2.8 in).

Typical Applications

• Solar power plants: mowing between and beneath panel rows without fuel or exhaust near the array
• Orchards, vineyards and terraced plantations
• Highway, railway and river embankments
• Municipal parks, cemeteries, school grounds and urban green belts
• Golf courses, resorts and private estates

Technical Specifications

Standard Accessories and Options

Included with every unit: remote control, toolbox, cutting blade set and smart charger.

• Front dozer blade (optional): push debris, level light material or clear snow, turning the mower into a year-round electric work tool.
• Multi-purpose storage rack (optional): carry tools and supplies across orchards, solar sites and estates.
• 48V 67Ah battery (optional): about 70% more capacity than the standard pack for longer shifts.

Frequently Asked Questions

What makes a brushless electric slope mower better for commercial use?

Brushless motors have no carbon brushes to wear out, run cooler and convert more battery energy into work. With no engine to service either, the YM-550 Brushless Electric spends more time mowing and less time in the workshop.

How steep a slope can it handle?

It is rated for a maximum working slope of 45° (40° – 45° depending on ground conditions), thanks to its low center of gravity and industrial rubber tracks. Always assess moisture and soil conditions before working steep ground.

How long does one charge last?

The standard 48V 40Ah battery gives 2 – 3 hours of operation depending on load. The optional 48V 67Ah battery extends runtime for large sites.

Is it suitable for solar farms?

Yes. Zero exhaust, no fuel on site, a low 460 mm profile and a 530 mm cutting width make it well suited to mowing between and around solar panel rows.

How is it different from the YM-550 Electric (Brushed Motor) version?

This version uses dual 500W brushless drive motors and a 2,000W brushless cutting motor for higher torque, longer motor life and no brush maintenance. It is the recommended choice for high-hour commercial and steep-slope work.
