Product Description This attachment is designed for engine-type brushcutters and is specifically created to minimize stone splashes and make mowing easier. It is suitable for mowing grass, weeds, and turf for light to medium work. Product Specification Size: Length 258 x Width 230 x Height 101 mm, Weight: 1.8 kg (including gear case) Reduction method (reduction ratio): Counter rotating gear reduction (upper blade 1:18.8 / lower blade 1:13.5) Recommended Brushcutter Engine: Displacement 23cc or more Appearance: Aluminum (A5052), Cutter: SKS5 and others Accessories: Mounting kit, Blade protection cover Features The reduction gearbox inside the attachment reduces the engine speed to about 1/20, allowing for efficient mowing even at low speeds and minimizing scattering of stones and debris. The rotary scissors drive of the upper and lower blades ensures smooth and safe mowing, even when encountering obstacles. The deceleration mechanism based on our original technology reduces vibration, resulting in smooth blade rotation. The up-and-down low-speed rotating scissors mowing system and simple waterproof structure prevent the blade from being sucked into the water surface and splashing back, making it safe to use near water, such as in paddy field furrows. The main unit can be disassembled for easy replacement and repair of internal gears. Precautions While this product has a scattering suppression effect, it does not completely eliminate scattering. It is important to wear protective gear and ensure the safety of your surroundings when using this product.

Although safer, cutting targets are limited and efficiency may be reduced. Standard blade with a good balance of both safety and efficiency. Can be used at many sites. The wide cutting width is most effective at sites where lawn care is frequently performed. The blade shape is 5 cm longer than the standard blade, making it effective for cutting lawn roots and edges.
