TIPS FOR USING BROADCASTERS
1.
WATCH YOUR SPEED! Do Not Go Too Fast For Conditions. If Ground Is Rough, Cut Your Speed.
Remember when seeder is loaded it causes much strain on A.T.V.s and hitch brackets when you start
bouncing through holes and rough ground. The hitches were designed for normal usage, so do not get
carried away and go too fast.
2.
As is common with all broadcast seeders, do not use on windy days as this will cause erratic spread,
especially with herbicides and may cause damage to crops in nearby fields.
3.
If your equipment (or vehicle) has a battery and charging system, keep your R.P.M.s sufficiently high
enough to charge at all times.
4.
The easy way to determine the ground speed of your A.T.V. or tractor is to set two stakes in the
ground, 88 feet apart, and check with the chart below.
At 2 M.P.H. you will travel 88 ft. in 30 seconds
At 3 M.P.H. you will travel 88 ft. in 20 seconds
At 4 M.P.H. you will travel 88 ft. in 15 seconds
At 6 M.P.H. you will travel 88 ft. in 10 seconds
At 8 M.P.H. you will travel 88 ft. in 7 1/2 seconds
5.
After determining the gear and throttle settings of the A.T.V. mark the settings so the throttle can be
returned to the proper location when broadcasting.
6.
This broadcaster is equipped with a centering pivot plate, which can be moved to center the spread of
material. To change location, loosen two capscrews holding pivot plate to bottom of base and move it
to a higher or lower letter by taking hold of the seed gauge and moving as explained in next step. A
good starting point is to move the seed gauge to the letter “C” for most Clover, Alfalfa and Fertilizers.
7.
If you see your spread is heavy on one side or the other, after you start to spread, do the following to
center the pattern of spread: (You distinguish the difference between right and left by standing
behind the A.T.V. or tractor and broadcaster and facing the direction the A.T.V. or tractor will travel.)
(a) When the pattern of spread is off-center to your right, move the pivot
plate to a lower letter.
(b) If your spread is off-center to your left, move the pivot plate to a higher
letter.
(c) Do not move over one letter at a time or you may over-correct.
INSTRUCTIONS FOR INSTALLING OPTIONAL BLOCKING PLATE 517
1.
Loosen two capscrews holding pivot plate to base and center pivot plate.
2.
Remove pivot screw and bushing in pivot plate that anchors agitator to pivot plate. Slide the blocking
plate under agitator and over the four protruding screws, making sure that protrusion lays down in
opening of pivot plate and blocking plate is flat against pivot plate.
3.
Replace pivot screw and bushing. Tighten but do not over-tighten. If it is over-tightened, end of screw
will extend through pivot plate in bottom and block movement of opening plate.
