Operator’s Manuals supplied with your
engines used on Lawnflite machines
are designed to run on
engine manufacturers recommend the
use of high quality detergent oil of
an API grade of SF or higher. The
general recommendation is that an
SAE30 monograde is used, but if the
machine will get frequent winter
use, an SAE10/30 multi-grade will
improve cold starting.
Lawnflite ride-on mowers have 12
volt lead acid batteries and the
electrical systems are “negative
earth”. While the engine is running
at full throttle the battery is
being charged but it should be noted
that it takes about 15 minutes of
full throttle running to replace the
electrical energy used in one start.
A consequence of this is that if the
machine is used in a frequent stop
start application the battery may
gradually become discharged.
electrolyte level in the battery
should be maintained by the addition
of demineralised water as and when
battery becomes discharged it should
be charged at a low rate – typically
not more than 1.5 amps. The majority
of chargers sold for automotive use
are not suitable as they have too
high an output. Suitable chargers
are available which may be left
connected for prolonged periods (all
winter) without ill effect.
machine is not going to be used
during the winter, the battery
should be disconnected, charged,
stored in a dry frost-free
environment and charged again before
being refitted in the spring. Jump

general rule tyre pressures of
between 8 and 15psi are acceptable.
However, it is important that all
four tyres are inflated equally. If
the pressures are not equal the
machine will not give a level cut.
usual reasons for uneven cutting
are: - the result of impact damage
and uneven tyre pressures.
ENGAGING THE CUTTERS
On machines with manual blade engagement use
about two thirds throttle, move the cutter
engage lever slowly to the fully engaged
position and then open the throttle fully.
All the time that you are mowing the
throttle should be left fully open. The
forward speed of the machine should be
controlled with the variable speed mechanism
not the throttle. BLOCKING
OF THE GRASS CHUTE & EXCESSIVE CUTTER BELT
The belts on Lawnflite machines are
automatically tensioned to compensate for
wear. Adoption of the following operating
procedures will prolong belt life and
achieve satisfactory grass collection.
operation of all controls, particularly
the cutter engagement lever – feel the
drive take up and feed it in slowly. If
the belt squeals you are possibly being
a bit heavy handed, if it smokes, you’re
in trouble!!! On machines with an
electrically operated cutter clutch the
blades should be engaged with the deck
fully raised and clear of the grass.
Don’t try to
cut too low or two fast – use the
variable ground speed control to
compensate for variations in the density
and volume of the grass being cut.
Keep the top
of the cutter deck clear of grass and
blades sharp – blunt blades put
excessive strain on the cutter drive
belt and cause premature wear.
underside of the cutter deck and the
discharge chute clean.
fabric of the catcher free from caked on
mud and debris.
POOR GRASS COLLECTION.
For the collection system to operate
properly the engine must be run at full
throttle all the time that the blades are
engaged. Forward speed of the machine should
be varied with the variable speed control
not the throttle. The usual reasons for poor
collection are either the grass is too wet,
too long, forward speed too high, dirty deck
and/or chute or internal fabric catcher
coated internally with dried mud preventing
it venting. ENGINE
