4.6 Setting Cutting Height
4.6.1 Multicut 300
With reference to Figure 4.12 - 4.14, to alter the minimum height of cut:
Start the tractor and gradually raise the machine until the rear wheels are off the ground.
Stop the tractor and proceed to adjust the rear wheel arms to the desired position.
Figure 4.11 – Multicut 300 Height Adjustment Dependent Variables
Multicut 300 machines can be set-up in a variety of different configurations through adjusting and
altering:
1. Wheel arm pin positions (ref Figure 4.11)
2. Wheel arm orientation (ref Figure 4.11)
3. Wheel yoke spacer positions (ref Figure 4.11)
By changing the combination of these various items and setting them up in different ways will give
different cutting heights from the machine.
For guidance cutting height settings; see Table 4.3.
Ensure that before proceeding to use the machine that all height pins are replaced and secured in
position with the supplied lynch pin and all wheel yoke spacer fasteners are tight.
Repeat the process on the other wheel arm so both wheel arms match in their set-up and return to the
tractor and gently lower the machine.
Table 4.3 shows a reference guide as to the minimum height of cut that will result. The data given can apply to
machines fitted with the standard tyre and laminated optional wheel as shown in Section 1.5.2.5.
This table of data is just for reference to create a ballpark figure for the customer to start from and assumes:
• Standard tyre pressures are correct, or the laminated wheel is not excessively worn or damaged
resulting in a reduced diameter
• Levelling is carried out on perfectly level and firm ground
• A brand new machine with no worn components
• The machine is perfectly set levelled front to rear as shown in Section 4.5.1
• The machine is perfectly manufactured and there is no tolerance variation in components
Due to this Spearhead shows the data below as a reference holding no responsibility for the machine not
achieving the exact quantities given in the table below. It is important for the operator to try out the machine at
the work site with the expectation that they will need to adjust the machine after to get exactly what they require
to fit the working conditions.
