How to Install Needham Ag V8 Firming/Press Wheel

Time needed: 5 minutes

Older style OEM firming press wheels are not shaped to properly fit into the seed trench resulting in seed that is not consistently placed. The Needham Ag Heavy Duty V8 Firming Press Wheel is flexible and designed to fit fully into the seed trench, ensuring each seed is pressed into the bottom of the furrow. This establishes good soil contact with the seed for more consistent germination and stronger stands.

NOTE: Most operators find that less down-pressure needs to be applied to the Needham Ag V8 Firming wheel compared to OEM wheels. By reducing the down-pressure to the mid position, around 10lb can be transferred to the disc blade to aid soil and residue cutting.

1. Remove old press wheel

   Remove the old firming press wheel from press wheel arm.

2. Position button-head bolts toward firming wheel arm

   Ensure that the round button-head bolts on the V8 wheel are positioned towards the firming wheel arm. See Figure 2.
