A typical turbocharged V8 diesel engine might have an engine power of 250 kW (340 hp) and a mass of 380 kg (840 lb), [1] giving it a power-to-weight ratio of 0.65 kW/kg (0.40 hp/lb). Examples of high power-to-weight ratios can often be found in turbines. This is because of their ability to operate at very high speeds.
Dixie Chopper claims to build the world's fastest lawn mowers. The most famous example was the Jet Mower, custom built by Art Evans in 1991 using a 150 HP Solar T62 APU from a Chinook Helicopter.

The motor may be attached to the end of the actuator. The drive motor is of typical construction with a solid drive shaft that is geared to the drive nut or drive screw of the actuator. Compact linear actuators use specially designed motors that try to fit the motor and actuator into the smallest possible shape.
The combustion cycle can be either two-stroke (which results in a lighter engine for a given power output) [3] [4] or four-stroke (which produce lower levels of exhaust gas emissions). [5] [6] The fuel is usually either petrol or diesel. [7] In 1973, a small Wankel (rotary) engine manufactured by NSU was used in a lawn mower. [8]
