The rams supporting the arms on Tempest have a constant supply of pressurized oil from an accumulator. This allows the hydraulic system to take most of the weight of any attachments fitted to the front of the machine. This in turn minimizes the down-pressure of the attachment on the ground. This ‘assisted float’ facility allows attachments to follow ground undulations easily, without digging in.
There is 10 µm filtration on the return line to tank, using a magnetic separator.
