Tips and Tech nique’s
• Each blade wing may be angled independently of the other. The wings can be angled
from 30º forwards, to 30º backwards.
•
Each blade wing is controlled with a 12V solenoid valve on the blade. To select which
blade wing is to be operated, simply change the position of the switch on the tractor.
Then move the auxiliary lever until the blade reaches the desired angle.
•
The V-Blade is equipped with adjustable skid shoes to allow ground clearance of
different heights. They can be adjusted high enough to allow the cutting edge to
scrape the surface being cleared or adjusted down to reduce the amount of displaced
gravel during snow removal.
• If the skid shoes are used to determine the depth of dozing, use the float position.
• Prior to dozing, ensure the work area is clear of obstacles, hazards, and personnel.
•
Down pressure may be used for digging or cleaning a hard surface, however, the
tractor’s steering ability may be reduced.
• Back dragging is ideal to spread loose material.
• Always lower the blade to the ground and retract both blade wings to the back
position, when not in use. This keeps the hitch arms up for attaching.
Spring Safety Trip Mech a nism
The KV550 blade is equipped with a spring
safety trip mechanism. This helps prevent
sudden unexpected stops caused when
contact is made with uneven sidewalk joints,
rocks, or other immovable objects. The
spring safety trip mechanism is unlocked
when the pin is in the outer storage hole
(see figure 1.) For heavy dozing, the pin can
be installed in the lockout hole, locking the
spring safety trip mechanism (see figure 2.)
This position is recommended only for
digging or scrapping at a very slow speed.
The V-Blade will not trip with the pin in
the Lockout hole!!
