Step Two: With the spreader gate closed fill
the hopper at least half full with a known
quantity of a material. Record the amount of
(Example50#)
material here
TIP: Usethe sameunits of weight or volume
that is used in the spread coverage from

Step One: Record the coverage you are
trying to obtain here
(Example15# per 5,000 sq ft). See material
driving over 10 mph.
If your material is not iisted above this
procedure will help you calculate the ATV
speedto get the correctcoverage.
Step Three: With the spreaderon, openthe
feed gate for one or two secondsand measure
the spread width for your material. Record
the spread width (diameter) here
