Why owners do it
On many mini excavators the engine sits directly under or behind the seat, so heat rises around the operator. A small fan on the canopy post and some insulation under the seat panel make long days noticeably easier.
What is involved
- Mount a 12 V fan on the canopy post, roll bar or a bracket behind the seat.
- Run a fused feed from the battery or an ignition-switched circuit through a switch.
- Add heat-reflective insulation to the underside of the seat panel or engine cover where it will not block cooling airflow.
Typical parts
- 12 V clip-on or bracket fan
- Inline fuse holder and fuse
- Switch and automotive cable
- Heat-reflective insulation mat
Check before you start
- Check the alternator or charging coil output before adding loads; small petrol units have little spare capacity.
- Keep cables away from the exhaust, the swing area and pinch points.
- Do not cover engine air intakes or radiator openings with insulation.
