Smartiger 40 Remote Mower for Extreme Slope Vegetation Control

This remote‑controlled slope mower combines a 40HP Yanmar diesel engine with a closed‑loop hydraulic system and Poclain track motors to handle vegetation on grades up to 55°. The 1.35m flail head cuts grass and light wood up to 30mm diameter, with hydraulic deck lift and auto‑float that follows ground contours.

Operating mowing equipment on steep hillsides, canal banks, and roadside verges creates constant rollover concerns. Even experienced operators hesitate before taking wheeled machines onto slopes beyond 30°. This tracked remote mower changes that calculation entirely.

The 40HP Yanmar diesel drives a closed‑loop hydraulic system that powers both the tracks and the flail head independently. Three piston pumps separate the circuits—one for the flail motor, two for the track drives—so cutter speed stays consistent even when turning or climbing. The Poclain high‑torque motors on each track provide the low‑end grunt needed for loose surfaces, while the 2‑speed transmission lets you shift between 0‑4 km/h for precision work and 0‑9 km/h for covering flat sections quickly.

The 1.35m flail head spins at 3000 rpm through its own closed‑circuit piston pump. Y‑flails cut grass and woody material up to 30mm diameter, and the rotor diameter (300mm) gives enough inertia to power through dense growth without stalling. Cutting height adjusts from 30mm to 90mm using the rear roller, but the hydraulic lift lets you raise the head up to 500mm above ground for transport or clearing thicker brush. An auto‑float function lets the deck follow ground contours up to 10° of tilt, reducing scalping on uneven terrain.

Safety systems go beyond the remote control. An angle sensor triggers a visual and audible alarm at 50° and shuts the machine down at 55° before a rollover occurs. Signal loss stops all functions within 2 seconds. The receiver screen shows water temperature, oil temperature, oil level, and rotor speed, letting you monitor machine health from a distance.

For contractors maintaining solar farms, orchards on steep slopes, flood control levees, or highway embankments, this mower eliminates the need for winch lines and spotters. The 1250kg operating weight and 750kg attachment capacity support other implements beyond the flail head, making it a multi‑purpose remote platform for challenging access work.

What slope angles can this mower actually handle?
The machine is rated for continuous work on slopes up to 55° in any direction. An angle sensor triggers an audible and visual warning at 50° and automatically shuts down the mower at 55° to prevent rollover. The rubber tracks with heightened teeth provide grip on loose or wet surfaces at steep angles.
How does the auto‑float function work?
The flail head follows ground contours up to 10° of tilt without operator input. This prevents scalping on uneven terrain—particularly useful on slopes with ruts, tussocks, or erosion channels. The deck rises and falls independently of the machine body.
What is the remote control range, and what happens if I lose signal?
Range exceeds 150 metres with line‑of‑sight operation. If signal is lost for more than 2 seconds, the machine automatically shuts down all functions. The remote uses 434MHz frequency, adjustable for export markets.
Can this machine cut woody vegetation, or is it only for grass?
The Y‑flails are designed for grass and light wood up to 30mm diameter. Thicker brush or saplings require heavier flail options. The rotor speed (3000 rpm) and 84 L/min oil flow provide sufficient inertia for dense growth, but the material size limit is 30mm for best blade life.
What maintenance does the hydraulic system require?
The system holds 40 litres of hydraulic oil total (23 litres in the tank). Filters are accessible from the side panels. The 2‑core radiator and optional self‑cleaning fan help manage heat in demanding conditions. Monitor oil temperature on the receiver screen during extended operation.
How do I transport this machine between sites?
Overall dimensions with the flail head are 2900mm long × 1500mm wide × 1300mm high. Total weight is approximately 1450kg with the flail head fitted. This fits on most plant trailers rated for 2‑tonne loads. The flail head is removable to reduce length to 2000mm for tighter transport configurations.
