The Yard Force MB400 robot lawn mower is an automatic lawn mower designed for the regular maintenance of small residential lawns. Its compact design, featuring a plastic housing and treaded rear wheels, makes it easy to manoeuvre on grassy surfaces with slight unevenness and gradients of up to 30%.
Automatic operation reduces the need for manual intervention and keeps the grass more uniform with frequent, close cuts.
The mowing cycle is carried out by three steel blades mounted beneath the 16 cm cutting deck. As the mower moves forward, the blades progressively trim the grass and the clippings remain on the ground as fine mulch. The centralised cutting height adjustment allows the cutting height to be set from 20 to 55 mm using a single control. The integrated control panel allows you to control the main operating functions directly from the top of the machine.
The main technical features of the Yard Force MB400 robot lawn mower are:
- 20V 2.0Ah lithium battery: battery-powered with no direct emissions and low noise levels. Suitable for routine lawn maintenance.
- 16 cm cutting width: ideal for small surfaces and narrow passages, makes it easier to work near borders and obstacles.
- Cutting system with 3 steel blades: the rotating disc ensures a smooth cut, while blade replacement is quick and easy.
- Lift, tilt and rollover sensors: immediately stop the blades from rotating in the event of abnormal movement of the machine.
- Forward speed from 0.2 to 0.4 m/s: controlled forward speed useful for maintaining a continuous cut even on uneven surfaces.
The compact cutting deck and low speed make it suitable for frequent maintenance. Less suitable for tall grass or surfaces left to grow for long periods.
