Overview
In small gardens and tight spots a mower cannot reach, the HJ604C works as a grass shear and converts to a hedge trimmer with a quick blade swap. An ergonomic handle and hardened steel blades come with it.
Swapping blades turns a grass shear into a hedge trimmer, and the tool is light and compact for cramped corners. A thin cutting width and a small battery limit it to light jobs.
Who it's for
Homeowners with small gardens who want a light handheld tool. Large properties need stronger trimmers.
Pros and cons
- Converts between shear and trimmer
- Light and compact
- Hardened steel blades
- Charger and blade covers included
- Thin cutting width
- Runtime not listed
Performance notes
A small motor drives interchangeable hardened steel blades, so the shear blade handles grass while the longer trimmer blade handles shrubs. The cutting width limits stem thickness, and runtime depends on the small battery, which the listing does not time.
