19-2. Installation of the mower unit
While engaging the hitch sections, slowly move the machine forward, and raise
the attachment mounting base to engage the hitch sections.
After confirming that the hitch sections are engaged completely, attach the lock
pin and secure it with 6 clip pin.
Set the cylinder single-/double-acting changeover switch in the "single-acting"
position.
After attaching the belt and adjusting the tension, attach the right crawler cover
and intermediate shaft belt cover, and the operation is complete.
19-3. Hydraulic cylinder single-/double-acting changeover
Before starting ordinary operation, be sure to set the cylinder single-/double-acting
changeover switch in the "single-acting" position, and change it to the "double-
acting" position before installing or removing the mower unit.
Operation with the changeover switch in the "double-acting" position will cause
the hitch sections to be subjected to a load when the machine climbs over a large
stone or some other obstacle, causing machine failure.
20. Gear oil change for traveling motor
The speed reducer of the hydraulic motor for traveling is filled with 0.35 litter of gear
oil. Flush the speed reducer 50 hours after initial operation and every 200 hours after
that, and after each flushing, fill the speed reducer with a new gear oil #140 (ISO
VG140).
Unless the oil is changed according to the specified time, the motor failure will result.
Be sure to change oil as specified.
