General Operating Instructions
Once you have read the operators manual, properly
attached the seeder to the tractors, ran through the
Operating Checklist, filled the hopper with seed, and
calibrated the unit for proper seed rate delivery, it’s time
to do some serious seeding.
The PS25120 has a ground driven seed delivery system.
The power to drive the seeder comes from the forward
momentum of the tractor. As the tractor moves forward
the ground driven front roller compactor transfers power,
via chain driven sprockets, to the seed metering system.
So, the seed rate remains constant and in direct
proportion to the distance traveled and is affected very
little by actual ground speed.
As the front roller passes over areas to be seeded it
crushes larger clods, presses down smaller stones, and
firms the seedbed. Seed is then delivered at the precise
predetermined uniform rate over the wind guarded seed
drop to the area located between the front and rear
rollers. The rear roller then presses the seed into firm
contact with the soil to promote a superbly high
germination rate. Seeding should not be attempted in
wet or muddy conditions.
Now that you understand how it works its time to begin
seeding. Make sure you have removed the rear roller lock
pin from the field or parking position.
You should already have removed any large stones or
obstacles from the area you plan to seed. Line the tractor
up for the first pass and choose a tractor gear selection
that will deliver a ground speed of approximately
3-5 mph. Lower the seeder slowly to the ground. At first
begin driving forward slowly until you get comfortable
with what you are doing. As you approach the end of the
lane you are seeding, slow down and come to a stop
while simultaneously raising the seeder off of the ground.
With the seeder raised, turn around and line up for your
next pass to repeat the seeding process. Look back often
and make only gradual turns with your seeder on the
ground to develop a uniform seeding pattern. The more
experienced you become the better you will get at
developing beautiful seed plots and beautiful lawns.
When you are done seeding, always clean the seeder out
and perform all maintenance prescribed in the operator’s
manual. Never leave seed stored in the hopper for
prolonged periods.
