INTRODUCTION
McCONNEL PT SERIES MOWERS - Medium Duty Pasture Toppers
Although designed primarily for the ‘topping’ of agri pastures the machines may also be used for
‘topping’ sports grounds and local council areas. These machines should never be used for
topping set-aside.
Our machines are designed with care and built with quality materials by skilled workers. Proper
assembly, maintenance and operating practices, as described in this manual, will help the
owner/operator get years of satisfactory service from the machine.
The purpose of this manual is to familiarise the owner/operator with the machine, and offer
guidance to ensure it is operated both safely and correctly for its designated task.
The parts section is designed to familiarise the owner/operator with replaceable parts on the
machine - this section provides exploded assembly drawings of the machines components,
illustrating each piece and identifying its part number.
Careful use, timely service and the fitting of genuine parts will save extensive repairs and costly
downtime. The operation and maintenance sections of the manual train the owner/operator how
to work the machine correctly and attend to appropriate maintenance tasks. The trouble
shooting guide helps diagnose difficulties with the machine and offer solutions to any problems.
Safety is of primary importance to the owner/operator and to the manufacturer. The first section
of this manual includes a list of safety messages that, if followed, will help protect the operator
and bystanders from injury or death. Many of these messages will be repeated throughout the
manual. The owner/operator/dealer should know these messages before attempting assembly
or maintenance and to be aware of the hazards associated with the operation of this machine
during assembly, use, and maintenance.
