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 engine speed be kept as high as
possible.
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 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 cutting cylinder to bottom blade adjustment every few hours even though
cutting performance appears to be satisfactory. Heavy contact or excessive clearances between the
cylinder and bottom blades will cause rapid wear to take place.
5. Always disengage the cutterhead drive when travelling across un-grassed 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 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 adjacent cutterheads by
avoiding tight turns.
8. It is generally wise to remove rear roller scrapers where conditions allow, as optimum grass dis-
charge is achieved without them. Scrapers should be refitted when conditions are such that mud and
grass start to build up on the rollers. When refitting the scraper wires care must be taken to ensure
that they are correctly tensioned, refer to MAINTENANCE - EVERY 50 HOURS.
WARNING: PREVENT ACCIDENTS - Take care when travelling over obstacles such as roadside
kerbs. ALWAYS travel at slow speed over obstacles to prevent damage to the machines tyres, wheels
and steering system. Ensure that tyres are inflated to the recommended pressures.
