Diameter 2 x 1000 mm - Hydraulic drive - 6 blades per rotor assembly - Floating discs - Honda petrol engine The Tremix double ride-on trowel Pro Rider is an easy-to run trowel for finishing large concrete surfaces. The machine is controlled by two joysticks that act directly upon the guiding valves. There are two foot pedals, one adjusting the revolutions of the engine, the other opening/closing the valves to the hydraulic engines. This allows a stepless start of the trowel. The "hydraulic pedal" acts at the same time as a "dead man's" grip. During trowelling or when driving close to obstacles the machine can be run at a very low speed, about 40 r.p.m., the maximum speed being approximately 140 r.p.m. The protective covers can easily be removed for blade change, servicing and cleaning. The support legs are provided with wheels that can be raised or lowered in order to facilitate change of discs and blades. The transport wheels and telescopic handles make the transport of the Pro Rider easy. The double ride-on trowel Pro Rider is highly versatile since it is easy to adjust the pressure upon the concrete surface to the concrete hardness. This can be done by modifying the blade angle hydraulically via a toggle switch. The joystick-control makes the control of the trowel handy and less tiring for the operator who can use the trowel in a more efficient way. The Pro Rider is equipped with an electrical water sprinkler system and a device to record the operating hours.
