SUMMARY
This mini hammer weeder attachment converts a compatible brush cutter into a compact weed-pulverizing tool for use around crop rows, between plants, under trees, in flower beds, inside greenhouses, and other narrow areas where larger machines are difficult to use.
Instead of simply cutting weeds and leaving long clippings behind, the high-speed free-hammer blades pulverize short weeds close to the soil surface. This significantly reduces the volume of cut vegetation and eliminates the need to collect the cut grass after operation. It is particularly effective on weeds approximately 10 cm or shorter.
FEATURES

- Pulverizes weeds instead of simply cutting them: High-speed free-hammer blades break short weeds into small pieces, greatly reducing the amount of cut vegetation left behind and eliminating the need to collect the cut grass after operation.

- Targets weeds near the growing point: The hammer blades work close to the soil surface and scrape weeds around the growing point while pulverizing the vegetation.
- High volume-reduction effect: Because the weeds are finely pulverized rather than simply cut and dropped, the volume of vegetation remaining after work is greatly reduced.

- Designed for narrow and difficult-to-reach areas: Ideal for crop rows, spaces between plants, around trees and shrubs, flower beds, planted areas, and greenhouse interiors where conventional mowing equipment may be difficult to use.
- Enclosed blade design: The hammer blades are contained inside the housing rather than being fully exposed, making it easier to work close to crops and other obstacles.

- 3-position adjustable head: The head angle can be adjusted to three positions, allowing the working orientation to be changed according to the location and direction of operation.
- Removable rubber cover: The reinforced rubber cover helps reduce the scattering of soil and debris during operation and also helps absorb operating noise.
- Easy access for cleaning: The cover can be removed, allowing soil, stones, and other material caught inside the housing to be cleared out.
-
Reversible hammer blades: The blades have usable edges on both sides. When one side becomes worn, the blades can be reversed to extend their service life.
SUITABLE WEED CONDITIONS
This attachment is designed primarily for routine management of short weeds rather than for clearing tall, dense, or heavily overgrown vegetation.

- Not suitable for tall or heavily overgrown weeds: Dense vegetation and tall weeds may not be pulverized sufficiently by the mini-hammer system.

- Recommended weed height: Approximately 10 cm or shorter.
- Particularly effective for young weeds and vegetation growing close to the soil surface.
- Regular use while weeds are still short allows the attachment to perform more effectively than waiting until vegetation becomes tall and dense.
COMPATIBILITY

The attachment includes a mounting kit designed to fit many engine-powered brush cutters. Check both the brush cutter pipe diameter and drive-shaft specification before ordering.
Pipe Compatibility

Power requirement: An engine displacement of 20 cc or more is recommended. For electric brush cutters, a motor output of 750 W or more is recommended.
Maximum power: Do not use with an engine or motor output exceeding 1.0 kW. Engines of 40 cc or more may damage the gears if the blades are subjected to strong impacts, such as when stones become caught in the mechanism.
