Seed Drive Setup
With the meters set up, the rate is adjusted by separate
Range and Transmission sprocket pairing at a ground
drive on each wing.
Sprocket Storage
Refer to Figure 4
Each wing has a pair of trees
containing both Range
and Transmission sprockets for that wing.
Note: The planter includes a standard set of sprockets
common to several implement models. Some
sprockets may not be used in presently offered
YP1630F configurations.
Range Setup
Refer to Figure 5
Range provides coarse seed rate control, and uses only
Driving:Driven sprocket combinations:
30T:20T or 30T:30T.
To change Range drive:
1. Consult the seed rate chart for your crop, meter, and
finger or cell count.
2. For your desired seed population, find the Range
sprocket pairing at the top of the chart.
3. Loosen the tensioning idler to obtain chain slack.
4. Remove the lynch pins at each Range sprocket
that needs to be changed.
5. Exchange sprockets with those required from the
storage trees. Re-install pins.
6. Engage the idler for 6 to 7 mm (
1 ⁄
4
inch) of chain
slack at longest chain span.
7. Repeat for other wing.
