Control Board and electrohydraulic valves assembly
All PRO/17 operating functions are carried out from a control board to be placed in the cabin. The control board is fed by 12 V, D.C. tractor battery through the relevant cable. It must also be connected to the feeding cable of the machine's electrohydraulic group throug a multiple plug which is easy to connect and disconnect. This allows to open ad close the rake crosspiece (frame), adjust the angle of the ranking sections separately of the right and on the left side, to lift and lower the raking wheels separately on the right and on the left side and to lift and lower them simultaneously on both sides by simply pressing the control board keys, which in turn activate the relevant valves to which they are connected.

Adjusting the wheel spring pressure, adjusting height
Each wheel can be regulated with the correct pressure on the ground through an adjustable rod connected to the relevant spring. A chain adequately anchored to the wheel lifting bar and to the wheel arm ensures a preset and sure stop to the wheel descent towards the ground. All these adjustments are individual for each single wheel. It also possible to adjust all wheels on each side by operating an adjustable sleeve located on the wheel lifting cylinders.

Sliding crosspieces (sliding frame)
A central frame made of doublesection structural pipes stabilizes the machine frame in irregolar fields. Fully open frame allows for 29' raking width.

Walking beams
Walking beams allow fast operation in irregular fields and easy road transport.
