Loading Seed
Fully loaded with dense seed, the drill weighs an addi-
tional 1536 or 1920 lbs (697 or 871 kg). Include this
weight when checking tractor capability.
The drill must be hitched for seed loading.
Inspect all boxes before loading. Remove any previous
seed or debris.
Load slightly more material than needed, because con-
sumption rates can vary between compartments even
though the furrow rates are identical.
Main Seed Box Loading
1. Check that all meter doors are positioned for the
seed size, and not set for clean-out. See “Position
Seed Cup Doors” in seed Rate Manual. If loading
prior to transport, set them to position 1 (smallest

2. Install or remove optional seed plugs as desired for
the row spacing planned. See “Seed Tube Plug
