Explore our 21V and 40V Cordless Grass Trimmers. Equipped with high-torque brushless motors, adjustable cutting heads, and telescopic shafts for maximum efficiency and comfortable yard maintenance.
You’re not alone. If you’ve been sourcing cordless grass trimmers for your market, you’ve likely run into these frustrating customer complaints:
Stalls in Thick Weed: The motor bogs down or wraps in tall, wet grass, forcing users to stop constantly and clear tangles by hand.
Troublesome Line Feed: Trimmer line that snaps too close to the spool, jams inside the head, or bumps inconsistently, ruining the lawn care workflow.
Battery Drain & Overheating: High-resistance cutting drains the battery in under 15 minutes or overheats the motor housing right when the yard is half-done.
Poor Balance & Back Strain: Awkward, top-heavy designs with fixed shafts that can’t be adjusted for height, forcing users to bend over and tire out quickly.
The real challenge? Finding a cordless grass trimmer that powers through dense growth — without line-jamming headaches, bad balance, or dying halfway through the lawn.
Explore our versatile range of cordless grass trimmers and brush cutters, engineered for effortless lawn edging, heavy weed clearing, and garden maintenance. Powered by high-efficiency motor technology and featuring multi-blade options with fully adjustable shafts, our series delivers flexible performance across residential and commercial landscapes.
Multi-functional cutting setup that easily switches between flexible nylon trimmer line for soft grass, high-strength metal blades for thick weeds and small shrubs, and manganese steel circular saw blades for dense brush and light branches.
Ergonomically designed with a tool-free adjustable telescopic shaft to comfortably match operators of different heights. Features an adjustable pivoting motor head (0°–90°) that tilts effortlessly for lawn edging, under-bench trimming, and sloped terrain.
Driven by robust brushed and high-torque brushless motors that deliver stable high RPM output for smooth, clean cuts. Operates with significantly lower noise and zero exhaust emissions compared to gas-powered trimmers, reducing operator fatigue and environmental impact.
Fitted with a high-impact protective debris shield and anti-collision wire frame to prevent blade damage against rocks and walls. Powered by a flexible 21V Makita-style pin platform (or dual-battery 40V setup for heavy duty), allowing seamless battery sharing across your entire tool lineup.

👉 Looking for a cordless drill manufacturer/ supplier in China you can rely on?
Let’s talk — and get you the performance your customers expect.
String Trimmer (Nylon Line): Best for cutting soft lawn grass, edging around flower beds, fences, and sidewalks safely without damaging hard surfaces.
Brush Cutter (Metal Blades): Best for cutting thick weeds, tough brambles, tall brush, and small saplings that nylon line cannot cut.
Only if the trimmer is designed for 2-in-1 use! Convertible models come with interchangeable heavy-duty heads. Never install metal blades on a light-duty string trimmer not built for them, as it can strain the motor and create a safety hazard.
It depends on the feed system:
Bump Feed: Gently tap the bottom knob of the trimmer head on the ground while it is spinning to automatically release more line.
Auto Feed: Automatically feeds out fresh line every time you release and pull the trigger.
Yes! Many models feature a 90° Swivel Head and Guide Wheel. Simply press the rotation button, flip the cutting head vertically, and roll along your driveway or sidewalk for clean, professional lawn edges.
2.0Ah Battery: Gives about 20–30 minutes of continuous trimming (ideal for small to medium home yards).
4.0Ah / 5.0Ah Battery: Gives 45–60+ minutes of runtime (best for large properties or tough, thick weeds).
Yes, for comfort! An adjustable shaft lets you set the length to match your height so you don't have to bend over, preventing back pain. The adjustable handle also keeps the tool balanced and easy to control.
Yes! Brushless motors deliver higher cutting speed (RPM) to slice through tall grass without bogging down or clogging, while extending battery runtime by up to 50%.
Three common causes:
Hitting hard rocks, brick, or concrete walls repeatedly.
Old, dry nylon line: (Pro tip: Soak your spool of nylon line in water overnight to keep it flexible and tough!).
Feeding line while jamming it into dense brush.
Yes, 100%! The standard kit includes:
1× Cordless Grass Trimmer Host
Rechargeable Lithium-Ion Battery & Fast Charger
Pre-Wound Line Spool / Plastic & Metal Blades (depending on model)
1× Safety Debris Shield & Auxiliary Handle
1× User Manual & Assembly Tool Set
(Charge the battery, snap on the safety guard, extend the shaft to your height, and you are ready to trim!)
