Hydraulic Systems

Motor
Substituting the lift cylinder with a gear motor, we can
now utilize our basic circuit to create rotational
movement to drive attachments. The adjacent photo
shows a hydraulic motor used to drive the reel on a
cutting unit.
Note that there are three hydraulic lines connected to
the motor shown in the photo. Many hydraulic motors
will have two larger hoses for the pressure and return
lines and a small case drain hose. The smaller case
drain hose carries fluid from internal motor leakage
back to the reservoir. A small amount of internal
leakage is designed in to these motors to lubricate
and cool motor components.
This illustration shows the basic circuit and
components necessary to drive the cutting unit reels.
With the spool in the upward position, the oil flow is
directed through the spool valve to the lower port
driving the motor in the forward direction.
Actuating the spool to the down position, the flow of
oil from the pump is directed to the opposite port of
the motor. The motor then rotates in the reverse
direction, such as when back-lapping the cutting unit.
