Before You Start
Each kit converts one Native Grass seeding row. Order
one kit per row that can accept an agitator. Make sure
each row is not so close to a partition that no agitator can
be installed there.
Due to interference with partitions, it may not be possible
to install a full set of four agitators blades at all seed
cups. Due to partition re-alignments over various model
years, you may have blades left over after the upgrade.
Have the following at hand:
• Basic hand tools
• Updated Parts Manual for the drill
• Operator’s Manual for the drill

2 Series II Native Grass Agitator
Installation
Preparation
0. If performing a complete Series II upgrade, install the
cup enhancements first.
1. Inventory the kit contents per the “Parts List” on
page 6.
Examine the new parts, noting that they are colorcoded for left hand (black) and right hand (plated or
green) placement. The Left fan-shaped agitators are
stamped “L”.
The (fan-shaped) Series II agitators each have two
blades; one flat, and one bent out slightly. The bend
will be away from the feeder sprocket in a correct
installation. In the normal direction of rotation, these
blades sweep seed toward the seed cup.
2. If you have just completed the Hex Shaft Update,
your shaft has no agitators installed, and the drive
chain is already dismounted. Skip to step 9.
3. Clean out any seed in box.
4. If necessary, move the drill to a dry well-lighted location suitable for disassembly. Park and secure the
drill. Secure the tractor if left connected.
