The low-emission engine was selected for its ability to provide ample power at low revolutions. Its position, between hopper and water tank, reduces in-cab noise levels and also facilitates ease of servicing, with all engine filters and service points being accessible from the large working platform.
The Scarab fluid drive system is directly coupled to the auxiliary engine. By eliminating drive belts, gearboxes and flywheel couplings, it ensures quiet, efficient sweeping and suction performance and a high degree of reliability. All the hydraulic control components are housed in a secure locker.
