Haymaker using rake wheels adjustment makes use of control unit to control cylinder adjuster units per wheel bearer to set wheel intervals.

摘要

The unit controls the rake wheel (11) adjusters in the form of electrically controlled piston and cylinder units, using a control program, with rake wheel bearers arranged in parallel in a unit hinged horizontaly to the machine (10) frame. The control unit includes position sensors for each wheel bearer and a control fitted service unit can pre-set the required rake wheel unit intervals. The rake wheels under control of the cylinders can be grouped in engaging pairs or opposed pairs of powered wheels and the swathe lay sensor is connected to the control unit so these set their respective rake wheels to the center of the swathe. Interposed between rake wheel units are telescopic bearers with each wheel unit mounted on a support wheel.
