Group 4.25, Exactrix Wing Injection. Replaces
Deere 1890, 1590, 1690, 1990, 1895 No-till
Single Disc Drills.
Three improvements added after June, 2006
Adaptable to Group 4.2 and can be added at any time to field seeding
Improvement 1. Three position mount.
Improvement 2. Plasma Tungsten Carbide
applied to advanced wear area.
Improvement 3. Line protection added to the
full length of the injection line with TIO adapter insert allowing
¼” or 3/16” injection lines.
Three position mount discussed.
Wing Low position.
Utilized for nurse crop seeding and tillage systems.
Wing High position
Utilized in No-till seedings.
Considered optimum mounting for most seeding conditions.
Wing Tilt position….added June, 2006.
Wing high position with injection angle tilted 30 degrees.
Allows the chrome insert to run parallel with the seed boot release.
Considered optimum for sandy soils and glacial till soils.
Tungsten Carbide Discussed.
A unique plasma application of tungsten
carbide to the TIO critical wear area .
Estimates of wear life increase vary from 2 to
5 times depending on mounting position of the Exactrix Wing
At the end of service the Exactrix Wing
Injector can be rebuilt with Tungsten Carbide.
Ideal for sandy soils and extreme service
Additional EVA Protection added.
A Gray protection sleeve of EVA is included at
opener assembly. The wear sleeve reduces external line wear in sandy
The TIO holder is set up for ¼” injection
lines…An adapter insert is added to the TIO holder when 3/16” lines
are in service.
The Group 4.25 Extreme Service option can
ordered from Exactrix and can be added to Group 4.2.
The option includes all the above features.
The option allows high speed 10 mph seeding in
Wear life is extended. However, Each soil type
will vary the length of the extended wear life.
To our knowledge this is the lowest No-tillage
banding cost for NH3 achievable….banding costs for wear parts should
not exceed 28 cents per acre. Reduced horsepower and fuel savings
