coordinated as shown below. The optional three spool valve allows for the operation
of a rear rotary mower or side ditcher. If the unit is equipped with a three spool valve,
do not operate the third spool handle unless a rear rotary or ditcher is mounted.
The rear mower height is controlled with the 3-point hitch control lever. Follow
the instructions for this control is the tractor operators manual. The tilt of the rear
mower is controlled with the third spool if the lift valve and is coordinated as shown
above.
The side and rear mower positions may optionally be controlled with the tractors
remote hydraulic connections or a combination of lift valve and remote hydraulics. If
so, determine which position of the side or rear mower is to be controlled be each
remote lever.

gauge or oil pressure gauge. If oil temperature reaches 200 degrees Fahrenheit,
stop mowers and see trouble shooting section for possible causes. Keep an eye on

MOWER OPERATION
When rotating parts are in motion, serious injury may occur if caution is
not used or danger is not recognized. Never allow bystanders within 300
feet of the machine when in operation. Extreme care should be taken
when operating near loose objects – such as gravel, rocks and debris.
These conditions should be avoided.
The rotating parts in this machine have been designed and tested for rugged use.
However, they could fail upon impact with heavy solid objects – such as steel guard
rails, concrete abutments, etc., causing them to be thrown at a very high velocity.
Never allow cutter head to contact such objects. Inspecting the cutting area for such
objects prior to mowing can help eliminate these potential hazards.
