The Mega Prof comes standard with the revolutionary ECO EYE™ by ELIET. This award-winning technology continuously monitors operation. Whenever the machine is not productive, the speed of the diesel (33 hp) or gasoline (37 hp) engine is immediately set to idle. An infra-red sensor monitors the feed zone. Whenever a person re-enters the zone, the engine comes back up to speed so it is ready to process the next load of pruned waste. The ECO EYE™ System reduces fuel consumption during downtime. It can save up to 200 litres of fuel a year. This design feature also limits noise and air pollution, thus reducing the impact of the Mega Prof on the environment and immediate surroundings.
