10.3 Raising the Unit
When hydraulic pressure is applied to the main lift circuit the main lift cylinders on the axle will begin to lift the
unit. When the Main lift cylinders reach full extension, the sequence valve diverts the hydraulic flow to the
tongue cylinder to level the unit.
When hydraulic pressure is reversed, the tongue cylinder will retract lowering the front of the Earthmaster.
When the tongue cylinder is fully retracted the sequence valve diverts the hydraulic flow back to the main lift
cylinders allowing them to lower the unit into the ground.
NOTE: The raising and lowering of the unit can be reversed at any time during the sequence without causing
problems.
10.1 Starting the Tractor
The procedure to start the tractor is model specific.
Refer to the tractor operator’s manual for starting
procedures for your particular tractor. Consult an
authorized dealer if the starting procedure is
unclear. Ensure the 3-point control lever is in the
lowered position and the PTO is disengaged before
starting the tractor. OPS-U-0033
10.2 Brake and Differential Lock Setting
Make sure the tractor brakes are in good
operating condition. Tractor brakes can be set to
operate independently allowing single rear wheel
braking action or locked together to provide
simultaneous rear wheel braking. FOR MOST
DRIVING AND OPERATING CONDITIONS, THE
BRAKE PEDALS SHOULD BE LOCKED
TOGETHER TO PROVIDE THE MOST
EFFECTIVE BRAKING ACTION.
Always disengage the tractor differential lock
when turning. When engaged the differential lock
will prevent or limit the tractor from turning. During
normal cutting conditions, locking the differential
provides no benefit and should not be used.
OPS-U- 0013
Be aware of the operating conditions. Do not operate the Tractor with weak or faulty brakes.
When operating down a hill or on wet or rain slick roads, the braking distance increases; use
extreme care and reduce your speed in these conditions. When operating in traffic, always
use the Tractor’s flashing warning lights and reduce your speed. Be aware of traffic around
you and watch out for the other guy.
