Charts
Thefollowingpagesare to assist in the proper setting of seeding rates
forthe 2N-2410,2N-2420, 2N-3010 and 2N-3020 FoldingNo-Till drill.
The rates indicated in the charts are approximate values. To assure
the most accurate seeding rate it is recommended that the drill be calibrated for the desired seed at the time of planting.

Setting the Seeding Rate
Calibratingthe seeding raterequiresfour steps:shiftingthe
speed-change gearbox, adjusting the seed-rate handle,
setting the seed-cup doors, and checking the seeding rate.
Checktheseed-ratecharts startingonpage 5 or in the drill
boxes. These charts list the proper settings for the speedchange gearbox and seed-rate handle for various seeds
and seeding rates.
The seed-rate charts are based on cleaned, untreated
seed of average size and test weight. The rates are based
on 11L x 15 8-ply rib implement tires and 265/70B16 skid
steer tires. Many factors will affect seeding rates including
foreign material, seed treatment, seed size, field conditions, tire pressure and test weight. Minor adjustments
likelywill be needed. Set and check the seeding rate using
theprocedures below,thenre-adjustthe rateasnecessary.
Before setting the seeding rate, rotate both gauge wheels
to see that the seed cups and drive are working properly
and free from foreign material.

Note:Eachdrillboxhas its own metering mechanism. After
adjusting and checking the rate on one box, set the same
rate on the other box.
Refer to Figure 1
1. Shift Speed-Change Gearbox
The speed-change gearbox is designed to give you a
varietyof speeds for differentseeds and seeding rates.
You can shift between four different drive types.
Referto the seed-rate chartsfor the correct drive type–
1, 2, 3 or 4. Move the selector handle on the gearbox
untilthecorrectnumberappears in the handle window.
Rotate the tires a few turns to confirm the gearbox has
engaged.
