• Two hands to be used when operating track controls.
• Pushing the control handles forward from the neutral
position causes the machine to move forward.
• Pulling the control handles back from the neutral
position causes the machine to move backward.
• Moving the track control handles farther from the
neutral position increases the speed.
• Steer the machine by moving one track control handle
farther than the other handle. This causes the track
on one side to rotate at a different speed than the
opposite track. Pivot turns can be made by moving
one control forward and the other control back.
11) Position the stump grinder so that the grinding disc is
just over the front edge of the stump.
12) '#%&,%&'(,%14(4-&/#-2+ To start the grinding disc,
hold down the thumb button on the control handle. Then
pull the trigger back. After the grinding disc is started,
the thumb button can be released, but the trigger must
be held to keep the grinding disc turned on. To raise
the cutter head, pull the cutter height control bar back.

moving the joystick control lever left or right.
13) '#%&,%&'( 1/0E!+(189:8(':;<L;<=( L;7?+ Using the
cutter head control lever, slowly swing the grinding
disc across the edge of the stump. Adjust cutting
depth and swing speed to prevent the engine from
losing RPM and to prevent grinding disc from stalling.
After the swing is complete, move the grinding disc
down a few inches and repeat the cutting swing.
Continue making a series of cuts down the edge of the
stump until the edge is cut to below ground level or the
teeth are cutting at a depth below half the grinding disc
radius. Depending on the diameter of the stump, it may
be necessary to move the stump grinder. After cutting
the rst edge, move the machine forward and repeat the
grinding procedure.
