Engine and workload
Makita’s 43 cc MM4 gives 1.5 kW — half as much again as Honda’s GX35 — and is designed as a professional, all-day machine. The GX35 has plenty of reserve for brambles and woody scrub on a garden or smallholding, in a smaller, lighter package. Both engines tilt freely while working (rotary-slinger on the Honda, multi-position lubrication on the Makita).
Weight vs vibration
The Honda is about 1 kg lighter and comes with a double harness. The Makita answers with very low vibration and practical pro touches: a universal guard for blade and line, a tool-less handle clamp and a multi-position engine. For hours of continuous cutting, low vibration matters as much as weight.
