b. Hydraulic System. The hydraulic reservoir (6) contains the oil needed to operate the
MHC. The hydraulic reservoir (6) holds 27 gal (102 L) of oil and is equipped with an oil
level gage (7). A fluid filter (8) is mounted on the reservoir to remove contaminants.
Hydraulic pressure is supplied by a single stage hydraulic pump (9) mounted on the back
of the PTO (10). Placing the PTO switch (11) in the on position causes the PTO drive
gear to engage with the transmission and drive the single stage hydraulic pump. A
manually operated hydraulic pump (12) allows you to lower any load to the ground and
stow the MHC if the single stage hydraulic pump fails.
