OPERATING THE MOWER

1.40

GENERAL OPERATING HINTS

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.

The quality of cut will deteriorate if the forward speed is excessive. Always balance the quality of cut

with the workrate required and set the forward speed accordingly.

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.

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.

Always disengage the cutterhead drive 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.

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.

Take care not to leave uncut strips of grass at the overlap points between adjacent cutterheads, by

avoiding tight turns.

It is generally wise to remove rear roller scrapers where conditions allow, as optimum 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. When refitting the scraper wires, care must be taken to ensure that they are cor-

rectly tensioned, refer - 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.
