<p>The clutch control system comprises a tensioner (5) for a transmission belt (12) between a pulley (11) on an IC engine drive shaft (10) and a second pulley (20) connected by a reduction gear (3) to an implement drive shaft (31). The tensioner is operated by a pneumatic actuator (6) fed with a vacuum from the engine (1) and connected to a control valve (61) with a lever (41) on a handle (40). The valve is located between two tubes (61, 60), one connected to the engine intake pipe and the other to the pneumatic actuator.</p> |
