3. Make sure the seed cups are not plugged with leaves, grass or other obstacles and
that the seed cup regulation levers are all adjusted to the same opening position.
4. Remove the seed tubes from the lower bar and attach bags to the ends to allow the
material to be collected.
5. Move the calibration handle located in the rear of the hopper to a position between 1
and 6
(see fig. 8)
.
6. Turn the roller by hand in complete turns for a minimum of 20 turns. The greater the
number of turns the more accurate the measurement will be.
7. Gather up and weigh all the material distributed in the bags. Divide this by the
number of turns the roller made. This will give the amount of material dispersed per
turn of the roller.
8. Each roller revolution, on the TR2058, corresponds to a surface area of 13.88
square feet therefore 72 revolutions equal to 1,000 square feet and 3,137 roller
revolutions equal to 1 acre. To obtain the amount of seed spread per acre, multiply
the quantity obtained with each revolution by 3,137
(see Table 2)
.
9. If the results do not correspond to the desired amount which needs to be distributed,
adjust the calibration handle accordingly.
TABLE 2 - WORKING SURFACE
72 revolutions = 1000 sq. ft.
3137 revolutions = 1 acre
1 revolution = 13.88 sq. ft.
TR2058
To calibrate the aerator-overseeder while it is working, do the following:
1. Measure out a predetermined distance on the ground (for example 200 linear feet),
keeping in mind that the further the distance, the more precise the measurement.
2. Fill the hopper with the seed you intend to spread.
3. Make sure the seed cups are not plugged with leaves, grass or other obstacles and
that the seed cup regulation levers are all adjusted to the same opening position.
4. Remove the seed tubes from the lower bar and attach bags to the ends to allow the
material to be collected.
5. Move the calibration handle located in the rear of the hopper to a position between 1
and 6.
6. Drive the tractor forward pulling the machine along the predetermined distance. It is
important for the roller to remain on the ground at all times and to roll continuously.
7. Collect all material distributed and weigh.
8. Using
Table 3
determine the amount of material distributed.
Example: If the
distance traveled is 100 ft. and 0.1 lb. of material is collected, then 9.2 lb. per
acre of material is being distributed.
9. If the results do not correspond to the amount that needs to be distributed, adjust the
calibration handle accordingly.
