3.09 - Seed (or Fertiliser) Hopper Calibration
There are two adjustments to be made to calibrate the Green-Rite hoppers:
1. the amount of gear inside the seed cup housing.
2. The position of the cleanout gate of each individual seed cup.
This system allows use of a wide variety of seed.
It is important to keep in mind that by being ground driven, the disbursement of the seed
in the hopper is totally independent from the tractor
PTO
or the ground speed.
The output of seed differs greatly depending on their size, density, dampness,
and shape.
Other output factors depend on the conditions in which the machine is
operating such as, in slick conditions where the roller may slip.
Table 1
lists the distribution rate in kilograms per hectare for various seed that may be
used in the Green-Rite.
Keep in mind that the hopper and seed cup openings measure in volume and not in
weight.
Due to the many variables, the distribution rate when using
table 1
is not always
accurate.

Use
table 2 and 3
to determine if the rate you are getting is correct.
There are two ways of setting the calibration on your Green-Rite:
1. with the machine stopped and raised,
2. with the machine attached to the tractor and working.
