General Operating Hints
1. The rotational speed of the cutting cylinders
should always be kept as high as possible in
order to maintain the highest quality of cut.
This in turn requires that the tractor engine
speed be kept as high as possible without
exceeding 540 rpm P.T.O. speed.
2. The quality of cut will deteriorate if the
forward speed is excessive. Always balance the
quality of cut with the work rate required and
set the forward speed accordingly.
3. Never let the tractor engine labour. Reduce the
forward speed or increase the height of cut.
Check that the cutting cylinders are not in
heavy contact with their bottom blades.
4. Regularly check the cylinder to the bottom
blade adjustment every few hours even though
cutting performance appears to be satisfactory.
Heavy contact or excessive clearances between
the cylinders and bottom blades will cause
rapid wear to take place.
5. Always disengage the tractor P.T.O. when
travelling across ungrassed areas. Grass will
lubricate the cutting edges whilst mowing.
Excessive heat will build up if the cutting
cylinders are run when not mowing and this
will cause rapid wear to take place. For this
reason it is also wise to reduce cutting
cylinder speed when mowing lightly grassed
areas or when the grass is dry.
6. Cutting performance is best when cutting
against the lie of the grass. In order to take
advantage of this fact, the operator should
attempt to alternate the direction of mowing
between cuts.
7. Take care not to leave uncut strips of grass at
the overlap points between the adjacent
cutterheads by avoiding tight turns.
8. It is generally wise to remove the rear roller
scrapers where conditions allow as best grass
discharge is achieved without them. Scrapers
should be refitted when conditions are such that
mud and grass start to build up on the rollers.
