Introduction
Great Plains welcomes you to its growing family of new
product owners. Your Discovator 8315-8324DVN has been
designed with care and built by skilled workers using qual-
ity materials. Proper setup, maintenance, and safe operat-
ing practices will help you get years of satisfactory use
from the machine.
Before placing the machine into service for the first time,
read and understand this manual, in particular the
“Important Safety Information”, pages 5 to 9. Have all
operators read this manual before allowing them to work
with the machine.
Description of Unit
The 8315DVN, 8318DVN, 8321DVN and 8324DVN are
pull-type, field finishing, one pass tillage tool. The
8315DVN, 8318DVN, 8321DVN and 8324DVN are three
section machines that fold for narrow (3m) transport.
A row of hydraulic-adjustable Turbo coulters or shallow
concavity disk blades fractures the ground and size residue
3.8 cm above the sweeps.
The Max-Mix shank pattern increases chemical incorpora-
tion, reduces windrowing, and helps eliminate banding.
Four rows of shanks on 71.12 cm centers allows for resi-
due to flow through the machine using the Max-Mix shank
pattern. The effective spacing of the four rows with a 22.9
cm sweep of shanks is a sweep overlap of 6.4 cm. The
shanks can fracture the ground up to 30.5 cm deep.
The DVN models offer optional shank configurations. The
configurations are k-flex spring with a minimum draft
shank, K-Flex spring with a flat shank, heavy duty magnum
spring with a minimum draft shank, or heavy-duty magnum
spring with a flat shank. A 22.86 cm sweep is available with
or without hard facing.
Various finishing attachments are available to customize
your tillage and residue requirements for your operation.
An optional rear hitch is available for pulling implement/
tanks that do not impose high vertical loads on the hitch,
e.g., vertical load < 350kg.
Brakes are optional on DVN models. Service brakes are
operated by air or hydraulic lines to the tractor. Chock
blocks are provided in both brake options to prevent move-
ment of the machine while not connected to the tractor.
Chock blocks are manually placed.
Do not modify the DVN except as instructed by Great
Plains. Do not use attachments other than as provided by
or authorized by Great Plains.
