Operation 16
MAN1248 (2/26/2018)
Cutting Height Adjustment
It is recommended that level cutting be practiced. This
is done by following these steps:
1. With the lower link from tractor attached, adjust
upper link so that height
A equals height B .
2. If tailwheel option is applied, adjust tail wheel
ratchet so that height
A and B remain equal.
NOTE: Under conditions where extension and flex are
used in uneven terrain, it may be feasible to employ a
hydraulic top link to the upper hitch.
PRE-OPERATION CHECK LIST
(Owner’s Responsibility)
___ Check hydraulic tank level using dip stick under
cap. Level should be 5" from bottom of stick.
___ Hydraulic oil (in tank) is above 50° F.
___ Check to ensure blades are sharp
,
secure
,
and
cutting edges are positioned in the direction of
crossbar rotation
.
___ Check to be sure gearbox is half full of 90W gear
lube and has vent plug installed.
___ Check to ensure PTO shaft universal joints and
all other lubrication points are properly serviced.
___ Check to ensure all safety shielding is properly
installed and in good condition.
___ Check to ensure PTO shielding rotates freely.
___ Clear mowing area of debris that could be picked
up and thrown by cutter
.
___ Check cutting height and cutter attitude.
___ Place tractor PTO and transmission in neutral
before attempting to start engine.
___ Review and follow all safety practices presented
on page 7 through page 13 .
NOTICE
■
Make sure all hydraulic connections are
tight and all hydraulic lines and hoses are in good
condition before engaging tractor PTO.

Keep hands and body away from pressurized
lines. Use paper or cardboard, not hands or other
body parts to check for leaks. Wear safety goggles.
Hydraulic fluid under pressure can easily penetrate
skin and will cause serious injury or death.

Make sure that all operating and service person -
nel know that if hydraulic fluid penetrates skin, it
must be surgically removed as soon as possible by
a doctor familiar with this form of injury or gan -
grene, serious injury, or death will result.
CONTACT A PHYSICIAN IMMEDIATELY IF FLUID
ENTERS SKIN OR EYES. DO NOT DELAY.

Do not disconnect hydraulic lines until machine
is securely blocked or placed in lowest position
and system pressure is released by operating
valve levers.
GENERAL MOWING

Look down and to the rear and make sure area
is clear behind tractor and cutter before operating
in reverse.
This cutter may be used for mowing in either forward or
reverse
.
Reverse mowing will enable you to cut close
to obstructions
.
When mowing in both directions
,
cutter
should be level front to rear
.
Cutter Head Hydraulic Lift
The cutter head is raised with a 3.5" single
-
acting
hydraulic cylinder
.
The cylinder
,
which lifts only
,
is con -
trolled by the tractor hydraulic controls
.
The head is
lowered by gravity
.
There is an orifice restrictor in the hydraulic line to con -
trol the descent
When mowing
,
set hydraulic valve in the neutral posi -
tion, unless using optional gauge wheel(s) then set in
float
.
This will allow cutter to follow the ground contour
.
Always use the tractor hydraulic system with built-in
float when available. On tractors with closed-center
systems that do not have float, you may lock the con
-
trol in the down mode. This will allow the head to float.
Please use Gauge Wheel option while using float oper
-
ation. See page 52.
Do not lock the control in the down mode on tractors
with open-center systems. Refer to the tractor owner's
manual or contact your dealer if you have questions as
to the type of hydraulic system used on your tractor.
Operate the open-center system that does not have a
float with the control in the neutral position. This will
not allow cutter head to float up when encountering
an obstruction.
For tractors without hydraulic controls, an auxiliary con -
trol valve may be used. It has three positions: pull out
to raise, push in to slightly lower, and push all the way
in and snap into detent to allow cutter head to float.
