WARNING

If you do not understand how a specific control
functions, or have not yet thoroughly read the
FEATURES & CONTROLS section, do so now.

Do NOT attempt to operate the tractor without
first becoming familiar with the location and
function of ALL controls.

ing brake and make sure the PTO switch is disen-
gaged and the motion control handles are locked in
the NEUTRAL position.

partment and hydraulic pumps.

the hydraulic release valves (A, Figure 3) located on
the pumps COUNTER-CLOCKWISE a maximum of
2 full turns.
