connecting the cutter tongue to the tractor
1. ensure the tractor is equipped with the correct
PtO shaft and the drawbar is set at the correct
length.
2. using the parking jack, position the tongue clevis
to the height of the tractor drawbar. adjust the
cutter tongue to be level and parallel with the
tractor drawbar using the control rod connecting
the cutter tongue to the deck.
3. Board the tractor and start the engine. Back the
tractor to the cutter aligning the drawbar hitch
hole with the cutter tongue clevis. Turn off the
tractor engine, place the tractor in park, and set
the parking brake before dismounting.
4. to attach the cutter, place two 1” flatwashers
positioned under top lip of tongue clevis and to
the top of drawbar. add additional 1” flatwashers
between the bottom of drawbar and bottom lip
of clevis to fill open space. Insert a 1” diameter
grade 5 or 8 bolt through clevis and drawbar
and retain in position with a 1” locknut. tighten
the locknut securely but do overtighten which
could spring or break the clevis. neVeR attach
the cutter to the tractor with a pin not having a
nut.
5. Securely attach the cutter safety chain to the
tractor drawbar or drawbar support frame.
6. Lower the jack until the tongue is completely
supported by the drawbar. Remove jack from the tongue and place on storage bracket of cutter.
Safety tow chain
If the cutter is towed on a public roadway, a safety chain with tensile strength equal to or greater than the
gross weight of the cutter must be connected between the tractor and cutter. this will help control the
implement in the event the tongue becomes disconnected from the drawbar. after connecting both ends
of the safety chain, drive the tractor to the right and left to check for proper chain length. adjust length as
necessary and allow only enough slack in the chain to make a maximum turn in both directions.
connecting cutter Hydraulic lines to the tractor
With the tractor shut down and secured in position, relieve hydraulic pressure from the tractor by moving the
control levers back and forth several times or placing the levers in the float position.
When connecting the cutter hydraulic lines, keep hoses, quick couplers, and swivels free of contamination.
Never leave a disconnected hose end open and cap the tractor hydraulic outlet ports when not in use.
If the tractor ports or cutter hydraulic hose ends become contaminated, wipe clean with a rag before
connecting.

rect PTO shaft and the drawbar is set at the
correct length.
2. Using the parking jack, position the tongue
clevis to the height of the tractor drawbar.
Adjust the mower tongue to be level and par-
allel with the tractor drawbar using the con-
trol rod connecting the mower tongue to the
deck.
3. Board the tractor and start the engine. Back
the tractor to the mower aligning the drawbar
hitch hole with the mower tongue clevis.
Turn off the tractor engine, place the tractor
in park, and set the parking brake before dis-
mounting.
4. To attach the mower, place two 1” flatwash-
ers positioned under top lip of tongue cle-
vis and to the top of drawbar. Add
additional 1” flatwashers between the bot-
tom of drawbar and bottom lip of clevis to
fill open space. Insert a 1” diameter grade
5 or 8 bolt through clevis and drawbar and
retain in position with a 1” locknut. Tighten
the locknut securely but do overtighten
which could spring or break the clevis.
NEVER attach the mower to the tractor with
a pin not having a nut.
5. Securely attach the mower safety chain to
the tractor drawbar or drawbar support
frame.
6. Lower the jack until the tongue is com-
pletely supported by the drawbar. Remove
jack from the tongue and place on storage
bracket of mower.
