Terraglide Front Axle Suspension - New Holland T7030 Operator's Manual

SECTION 2 - - CONTROLS, INSTRUMENTS AND OPERATION
TERRAGLIDE™ FRONT AXLE
SUSPENSION (where fitted)
The optional, self-levelling, front axle suspension will
provide improved stability, control, comfort and
traction. Terraglide is automatically activated each
time the tractor is started but will not function at
speeds below 1.5 k/mh (0.9 MPH).
When operating at speeds up to 12 k/mh (7.4 MPH),
the front axle suspension may be locked out if not
required.
To lock out the suspension, press the top of the
switch (1) on the control panel, a warning light (2) on
the instrument panel will illuminate to confirm the
suspension is locked. Press the top of the switch
again to reactivate the suspension facility.
At speeds above 12 k/mh (7.4 MPH), the suspension
will automatically re--engage, overriding axle lock
out. In this situation the warning light will remain on.
NOTE: Should the lock out switch warning light begin
to flash, this would indicate a malfunction of the
suspension system. Consult your authorised dealer.
IMPORTANT: See Ballasting and Tyres, page
3- -144, regarding the use of front end weights with
front axle suspension.
WARNING
Hydraulic oil in the front axle suspension system
operates under very high pressure. Escaping
hydraulic oil under pressure can penetrate the skin
causing serious injury. Unqualified persons should
not attempt to disconnect any pipework in the front
axle hydraulic system. Failure to follow these
instructions can result in serious injury.
WARNING
If a transmission ratio is engaged, with the engine
running and the tractor supported on axle stands, the
self-levelling function of the suspension may cause
the axle to make corrections (move up and down).
The suspension should be locked out to maintain
stability.
