Tractor preparation
WARNING:
Ensure that all operators have read and thoroughly understood all the safety procedures. For
further information refer to the relevant sections of this manual.
WARNING:
When connecting the machine to a tractor there is a risk of personal injury. Failure to follow the
safety instructions could result in serious injuries to either yourself or others. Therefore, when
connecting the machine and the tractor you should:
a)
Make sure the tractor cannot roll.
b)
Make sure that the tractor and the machine have compatible category attachments.
c)
Never stand between the tractor and the machine during attachment.
d)
Use the hydraulic three-point linkage slowly and carefully.
e)
When carrying out an attachment you must make sure that the machine is placed on a firm and
level surface.
5.2.1
Tractor requirements
Before fitting the machine to the tractor ensure that the specification of the tractor meets the requirements listed
below.
Tracto
r has a PTO output shaft which conforms to the ‘Machine general specification’ in chapter 1.0.
Tractor has a PTO output speed which conforms to the ‘Machine general specification’ in chapter 1.0.
A tractor top link is available (if required.)
Once the machine has been mounted to the tractor unit check the following;
The correct amount of fore/aft stability ballast has been added to the tractor front weight tray. The amount will
vary depending on type of tractor used and prevailing conditions.
The correct amount of lateral stability ballast has been added to the rear wheel opposite to the side shift
movement (if available). The amount will vary depending on type of tractor used and prevailing conditions.
NOTE: Some Spearhead machines are capable of being deployed on both sides of the tractor, in such case
lateral ballast may be required on both rear wheels.
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 cutting
unit is fully side shifted the load on the rear tyre on the cutting side increases.
Spearhead does not endorse the use of water ballast within tyres as this can have adverse effects on fore aft
stability at speed.
Check the run of the PTO for clearance. If necessary, remove the tractor drawbar or position it to one side so it
does not foul on the PTO shaft. Redeploy or remove any items which are likely to contact the PTO in operation.
The machine is connected to the tractor on the 3-point hitch and will accept either CAT I or CAT II linkages. The
tractor must also be equipped with a levelling box. If the tractor is fitted with a swinging drawbar, this should be
set in its shortest mode or removed completely. The tractor should be equipped with a six-splined PTO.
