The layout and naming convention used throughout this manual are as follows: For a clockwise output from the tractor
unit, see Figure 1.3, the centre Gearbox has a clockwise cutting action; and the RH gearbox has an anti-clockwise
cutting action.

Notes:
(1) Spearhead Machinery constantly reviews and improves product designs and reserve the right to change
this information. As a consequence actual machines may vary from specification. Contact your Spearhead
Sales representative if you have any queries.
(2) This specified geometric maximum is stated for information purposes only. It does not imply that it is safe or
appropriate to cut material in this position. The actual safe maximum side cut height will depend on the
width of the tractor that the implement is mounted to.
(3) The transport width quoted is a half width and is measured to the PTO centre which is notionally assumed
to be on the tractor centreline. As a consequence the full on road width is the quoted transport width plus
half the tractor width plus (or minus) any mounting offset from the tractor centreline.
(4) The transport depth is indicative and will vary with the specified tractor. This figure assumes a reference
dimension of
766mm
between axle centre and lower link pin centre.
(5) All dimensions are determined from computer models. As a result actual measurements may vary as a
result of deflections due to weight. Tractor tyres will naturally compress on the working side of the tractor as
the centre of gravity shifts. The amount is affected by tyre construction, age, inflation pressures and the
use of local ballast weight. For example a 20mm compression of the cutting side rear tyre will be magnified
by the offset reach which will have an effect on the actual cut height.
