Huayee mini excavator, HY-12M4 (trencher, backhoe) adjustable track

Huayee HY12M4 mini excavator – more stable, more advanced than its predecessor.

The Huayee HY12M4 is based on the well-proven HY12M3, supplemented with an adjustable track width

The biggest technical innovation is the piloted side hydraulic joystick and the single-cylinder, air-cooled KOOP engine

In addition, Huayee engineers also paid attention to comfort: thanks to the vibration-absorbing brackets and soundproofing solutions, the HY12 is remarkably quiet compared to similar 1-cylinder machines, working from the seat there is much less shaking, no bouncing, no “jumping” Chinese experience – this is a truly workable small machine.

Main characteristics:
Engine: Koop 192 1-cylinder diesel engine
Own weight: ~1150 kg
Boom: foldable (swing boom) + inverted boom
Digging depth: up to 1760 mm
Machine width: approx. 940 mm
Undercarriage: rubber tracks
Dozer blade: standard
Hydraulic cooling: YES

Gift: 38 cm bucket and quick coupler – included in the price

What it offers you in addition:

✅ Counterweight at the rear: greater stability even with heavier attachments
✅ Inverted boom: protected working cylinder, longer service life
✅ Quieter, less vibration: more comfortable working all day
✅ Deeper digging capacity: 1760 mm – capable of much more than its size suggests
✅ Quick coupler as a gift – bucket change in seconds

We recommend it to you if:

you already liked the HY12M3, but you want a machine with adjustable track width
you are bothered by the bouncy machining – and you would rather work more comfortably
you want a compact, but seriously usable machine for the long term
you are important to detail quality, reliability and long service life
