Spring platform Adjustment
The factory setting is both springs set at the most
forward position. The more rearward the spring
position, the stiffer the platform gets. Adjustment
will be to preference of feel. The two adjustment
springs should at all times, be positioned next to
each other not one forward or back more than the
other. To adjust, loosen each spring retaining bolt
from the top just enough to slide it, then tighten
with impact wrench. The nut may spin using hand
wrench. NOTE, do not loosen too much, if the nut
falls off, the foot platform will have to be removed
to reinstall. There is an extra hole for a third spring
for operators heavy enough to bottom out the duel
spring stock set up.

How to Move the Mower if the Engine
Won’t Start
Rotate both of the hydro bypass valves on the side
of each hydraulic pump about ½ turn
counterclockwise. It is important not to over
tighten these. Damage may occur to the pump if
this valve is over tightened.
Bleeding Air from the Hydraulic System
Whenever servicing the hydraulic system, it is of
the utmost importance to keep any dirt or debris
from getting into the system. Clean off all parts
before disassembly and assembly. When any of
the hydraulic parts are disconnected or removed or
when the oil is changed, air must be bled from the
system. If air is entrained in the system, loss of
power, excessive heat, and damage to the
hydraulic pumps may occur. First, make sure the
oil level in the reservoir is correct. The oil should
be level with the bottom threads of the oil level
