Machine Preparation

3.1 Prime Mover Requirements

Before fitting the machine to the tractor ensure that specification of the tractor meets the requirements listed
below.

3.2

Prime Mover Checks

  Availability of prime mover hydraulic service where the available flow is 50 to 80 litres per minute.
  A suitable mounting interface to the prime mover is available.
  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 head is deployed in work at the furthest reach 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.

3.3 Lifting The Machine

The machine will normally be delivered with the arms fully assembled to the support frame, but with the cutting
unit detached. If this is not the case then specific re-assembly instructions will be provided with the machine.

WARNING!

Only personnel experienced in lift and hoist operation should be involved in lifting machines.

The lifting points; indicated in the Machine general specification in chapter 1

– ‘Machine description’; are for

machines without the cutting unit attached. Ensure the correct points are used to suit the machine's condition,
as the centre of gravity changes with different configurations (head attached / detached) - Exercise caution!

3.4

Controls Overview

Your Spearhead machine will be supplied without a control system and will rely on the auxiliary controls
available with the prime mover. The operator must make sure he is familiar with the use of the prime mover
auxiliary controls. Refer to the prime mover operator manual for guidance.

3.5 DIN Mounting To The Prime Mover

The Twiga Carrier attaches to a variety of prime movers via a DIN type interface.  The prime mover can be a
tele-handler or front loader arms on a tractor, for instance.  With these types of machines, an interface kit is
usually supplied that will integrate to the quick-attach system, or otherwise the Twiga Carrier can bolt straight on
with the aid of the multiple mounting holes supplied on the back of the mounting plate, see Figure 3.5.1

The attached images show a plate system used on a front loader unit.  The unit uses a quick release pin that is
actuated from the tractor to secure the load onto the loader arms, and a hook arrangement at the top.
