Section 1 – Introduction
To the Owner/Operator:
OLIMAC SRL wants to thank you for purchasing a Drago GT Corn Head. Before starting harvest, please read
and understand this manual carefully to learn how to operate and service your corn head correctly. Failure to
do so could result in personal injury or equipment damage. If any portion of this manual is not understood,
please call OLIMAC SRL.
This manual should be considered a permanent part of your corn head and should remain with the corn head.
Measurements are given in both metric and customary US unit equivalents. Use only original replacement
parts including fasteners. Metric and inch fasteners may require a specific metric or inch wrench.
Right-hand and left-hand sides are determined by facing in the direction the implement will travel when
going forward.
Warranty is provided as part of OLIMAC SRL support program for customers who operate and maintain their
corn head as described in this manual. OLIMAC SRL warranty assures that OLIMAC SRL will warrant its
product when manufacturing defects appear within the warranty period. Should the equipment be abused, or
modified to change its performance, beyond the original factory specifications, without prior approval from
OLIMAC SRL, the warranty will become void. Use of non OLIMAC SRL approved lubricants will void the
warranty.
Write product identification numbers in the appropriate section below. You will need these numbers when
