Machine Preparation
4.1
Tractor Requirements
Before fitting the machine to the tractor ensure that specification of the tractor meets the requirements listed
below.
4.2
Tractor Checks
Availability of a PTO output shaft which conforms to the
‘Machine general specification’ in chapter 1.0.
Availability of a PTO output speed which conforms to the ‘Machine general specification’ in chapter
1.0.
A tractor top link is available if required.
To ensure fore aft stability ballast may need be added to the tractor front weight tray. The amount will
vary depending on type of tractor used and prevailing conditions.
Once the machine is mounted to the tractor and the tractor is correctly ballasted ensure that the
maximum axle loads for the tractor have not been exceeded. Failure to meet this requirement may
render the operator liable for infringement of public highway regulations.
Ensure that the tyres fitted to the tractor are correctly rated for the total working weight. NOTE: When
the flail mower is side-shifted or offset to its maximum capability the load on the rear tyre on the cutting
side increases significantly.
Spearhead does not endorse the use of water ballast within tyres as this can have adverse effects on
fore aft stability at speed.

WARNING!
Only personnel experienced in lift and hoist operation should be involved in lifting machines.
The lifting points are indicated in the Machine general specification in
chapter 1 ‘Machine description’. Use lifting
equipment suitable for the weight of the machine see section 1.4 Machine general specification for machine
mass. - Exercise caution!
