52cc Petrol Backpack Blower, 80m/s, 7800rpm, Full Crank Engine

A backpack blower is what you buy when clearing takes hours rather than minutes. A school ground, a hotel or lodge compound, a church yard, a stadium, a factory yard or a farm. The weight sits on your back and your shoulders rather than hanging off one arm, so you can work through a morning instead of swapping hands every few minutes.

The engine is a 52cc two stroke with a full crankshaft, which is the design used where a machine runs at high revolutions for long stretches. It turns to 7 800 revolutions a minute and pushes air out at 80 metres a second, which is fast enough to move wet leaves, packed grass, sand and light building debris off a hard surface. The supplier notes a redesigned impeller and cooling system, and cooling is the thing that decides how long a blower survives when it is worked hard in the sun. The back frame is set at 60 degrees with a shoulder strap, which is what keeps 8.8kg off your lower back and stops the machine digging into one shoulder. The throttle sits on the tube in your hand, so the speed is set where you are looking.
