Excel 323 Reach Mower

Introduction

The Excel is a very robust high capacity reach mower that is easy to operate and

maintain. Ideally suited to compact tractors engaged in the task of maintenance

mowing of green vegetation and annual hedge trimming. To ensure trouble-free

operation this manual should be carefully studied

The term Left and Right hand applies to the machine when coupled to the tractor and

viewed from the rear, this also applies to the tractor.

Tractor Requirements

•Check your Tractor size and minimum weight on the Specification table

•Before hitching, ensure position control is selected. Do not attempt to hitch in

draft control.

•Set wheel width as wide as possible.

•Ballast weight is to be fitted within tractor manufacturer’s recommended

requirements

•Check chains and stabilisers must be in good working order to hold the

machine firmly. Do not operate without checking chains and stabilisers are

tight.

•Spearhead particularly recommend ‘turn buckle’ type stabiliser.

•Set linkage lift rods to an equal length

•Certain machines require a 12V fused electric supply that is controlled by the

tractor’s ignition key.

•Spearhead particularly recommend “Category 1” three point linkage of ball

end type, we do not advise the use of claw type hitching. The quick release

latches should be checked, if worn or insecure they may cause accidental

damage or personal injury if the machine becomes detached.

•Ensure tractor link arms can be isolated from accidental lifting.
