1. Dear Owner
In buying a Kuhn machine you have chosen wisely. Into it have gone years of thought, research and
improvement. You will find, as have thousands of owners all over the world, that you have the best that
engineering skill and actual field testing can produce. You have purchased a dependable machine, but only
through proper care and operation can you expect to receive the performance and long service built into it.
This manual contains all the necessary information for you to receive full efficiency from your machine. The
performance you get from this machine is largely dependent on how well you read and understand this
manual and apply this knowledge. Please DO NOT ASSUME YOU KNOW HOW TO OPERATE AND
MAINTAIN YOUR MACHINE before reading this manual carefully. KEEP THIS MANUAL AVAILABLE FOR
REFERENCE. Pass it on to the next owner if you re-sell the machine.
Your KUHN dealer can offer a complete line of genuine KUHN service parts. These parts are manufactured
and carefully inspected in the same factory that builds the machine to assure high quality and accurate
fitting of any necessary replacements.
About improvements
We are continually striving to improve our products. We therefore reserve the right to make improvements
or changes when it becomes practical to do so, without incurring any obligations to make changes or
additions to the equipment sold previously.
Wear parts
Wearing parts fitted on our machines have been tested in very different situations to optimize their service
life. Nevertheless, the service life depends highly on theconditions of use (products to handle, soil, weather
conditions, etc...).
Designated use of the machine
The GMD4410 mower must only be used for the purpose for which it was manufactured: mowing on the
ground of hay fields, grass silage fields and improved pastures for the purpose of harvesting fodder for
feeding livestock.
Document illustrations
The illustrations in this manual may be based on one type of machine only. However, all instructions apply
to all machines covered in this manual.
