*Alternative oil must meet with East Wind oil specification, using unspecified oil may damage your engine and void warranty.
12. Brakes: The two pedals on the right foot operate
the brakes. In normal use they will be coupled
together. They can be simply uncoupled by the
“swing lever” situated behind the pedals and used
independently to facilitate sharp turning. Brake
adjustment can be made using the lock nuts
protruding from the brake housings. The brake
housings are on either side, below the seat.
13. Park Brake:
The park brake is set by hand using
a brake pedal lock lever. Always apply park brake
by pushing brake pedal first. Park brake must be
applied when the tractor is stationery.
14. Transmission:
● The Tractor is equipped with heavy straight
cut bull gears. When using the selectors, do
not apply excessive force to the levers as this
will only cause damage. Double Clutching, that
is depressing and releasing the clutch several
times will facilitate selecting the gears. Another
method is to apply light pressure to the lever and
gently release the clutch till the gears align and
selector eases into position.
●
Gear Selector: Tall lever located in the
prominent position. 4 forward and 1 reverse.
●
Range Selector: Heel and toe lever on the right
hand side of the gear box housing. Toe down –
high range, heel down – low range. It is used to
select high or low range. Use low range when
high power low speed is required such as filling
the front end loader bucket.
15. PTO Selector: 3 position lever located on the left
hand side of seat giving 540 and 750/1000 rpm
with neutral in the central position. The secondary
pto speed is 750 on the ZB25 and 1000 on the ZB
35.
16. 4WD Selector: Located behind the left foot
position when sitting in the seat, selecting 2 or
4 wheel drive. Select 4WD when required for
traction, and then disengage. Never use 4WD on
hard standing as it is likely to damage the drive
train. It will also reduce your manoeuvrability and
wear out the front tyres. Use 4WD only when
needed.
17. Diff - Lock Pedal: Located behind the right heel.
Engage in low range by tramping on the pedal at
low engine revs. Never use the diff-lock at high
speed or when turning.
18. Three Point Linkage: Control lever located
beside the seat on the right hand side. When
not in use this lever should be returned to the
neutral (middle) position. Push forward to lower,
and then return the lever to neutral. Push back to
raise, then return the lever to neutral. It is good
safety practice to lift implements only as high as
required to clear obstacles.
19. Response Control Wheel: Located below the
front of the seat. This is a ‘needle valve’ that
controls the flow of oil to the lowering of the three
point linkage. Turn clockwise to reduce the flow
rate slowing the downward movement of the
three point linkage, or anti clockwise to increase
its speed of movement. When screwed right
down, it will lock the position of the three point
linkage. Never climb under an implement on the
three point linkage that is not supported by a
mechanical safety device.
20. Hydraulics: Front End Loader. Do not start
the tractor while the hydraulic hoses are
disconnected. Warning signs are posted on the
side of the front end loader near the quick release
couplings. On parking and turning the engine off, it
is good practice to release the hydraulic pressure
in the lines. Once the engine is off, select ‘float’
position (loader lever in the “Full up” position) for
a few seconds to release the hydraulic pressure
in the lines. Always return the lever to the centre
(neutral) position. Never operate the three point
linkage whilst the loader control is in float position.
21. Tyre Pressure:
Tyres are the shock-absorbers
of the tractor. The correct pressure will vary with
operating weight and track conditions, and be
around 15psi for the rear tyres and 30psi for the
front tyres. All tractors with front end loaders fitted
have their rear wheels half filled with water. Lug
tyred rear wheels have wheel weights fitted.
