The GreenBay GB-LM 46 SH lawnmower is a self-propelled (rear-wheel drive) gas mower with a 4-in-1 cutting system, perfect for maintaining medium-sized lawns up to 1150 m².
It is powered by the reliable Honda GCVx145 OHV engine, a 4-stroke engine with Overhead Valves (OHV) and 145 cc displacement. This engine delivers a nominal power of 4.5 HP (with an effective power of 4.02 HP), ensuring very low fuel consumption and compliance with the latest European directives regarding emissions and noise.
4-in-1 Versatility and Cutting System
The GB-LM 46 SH model offers high versatility thanks to its 4-in-1 cutting system, allowing you to choose between:
- Collection: With a large, reinforced 60 L collection bag.
- Mulching: The Mulching kit is included as standard and finely shreds the grass, returning it to the lawn as natural fertilizer.
- Side Discharge: For quickly ejecting large volumes of grass clippings (Side discharge deflector included).
- Rear Discharge: Standard functionality to deposit clippings directly onto the ground behind the mower.
Changing the cutting mode is quick and tool-free. The cutting width is 46 cm and the cutting height is centrally adjusted via a single lever in 7 different positions, ranging from a minimum of 25 mm to a maximum of 75 mm. It is suitable for grass up to a maximum height of 35 cm.
Comfort and Maneuverability
The rear-wheel traction makes the job easier and more effective on any lawn, especially uneven ones. Maneuverability is improved by the high rear wheels (230 mm) mounted on ball bearings. To facilitate transport and storage, the mower features a foldable handle and a soft, rubber-coated grip for operator comfort.
