With the seeder loaded and raised for transport, certain
drawbar capacities could be exceeded by negative
tongue weight, see “Tractor Drawbar Hook-Up” on
page 14.
Tractor 3-Point Hook-Up

General Description
The following information is a brief description of how this
implement works. It is included to help you understand
the operation of this seeder.
The power to drive the seeding function of this seeder
comes from the ground speed of the tractor. The seed
metering is powered by the front roller at a rate
proportional to the distance driven. This ensures that the
rate applied in pounds per acre or pounds per 1000
square feet remains constant as ground speed is varied.
The power is transmitted via drive chains to the seed
cups. This drive can be adjusted to a high or low range to
broadcast more or less seed. The seed rate is adjustable
using the seed rate lever located at the rear of the
seeder. The seed is dropped between cast iron rollers.
The front roller crushes clods, presses down small
stones and forms a firm seedbed. The rear roller firms
the soil around the seeds.
Operating Check List
In addition to design and configuration of equipment;
hazard control and accident prevention are dependent
upon the awareness, concern, prudence and proper
training involved in its operation, transport, maintenance
and storage of equipment. Before beginning to operate
your Primary Seeder, the following inspection should be
performed.
Tractor Requirements
