GT3000A
UPDATES AND IMPROVEMENTS |
|
| |
| Drum
brakes have been replaced by
power assisted disk brakes.
|
|
|
| These
brakes use a 15 pound rotor and high
temperature (900 degrees) molded
pads for fade free
performance. The calipers
include self adjusting parking brake
actuators to eliminate the
requirement for the operator to
adjust the parking brakes. |
|
|
| In
addition, a switch has been added to
the parking brake lever so that the
tractor cannot be driven with the
brake applied (the engine will not
go off idle if the parking brake is
applied while the transmission is in
gear). |
|
|
| A
parking brake lever return spring
assures that the lever returns all
the way to “off” every time, all
the time. |
|
|
|
|
|
|
| New
Instrument Panel |
| The
new removable instrument panel tips
the gauges up for improved
visibility and improves
serviceability. |
|
 |
| Industrial
Air Cleaner |
| The
hat type automotive air cleaner has
been replaced with an industrial
dual element cartridge type
air cleaner. This really cleans up
the engine compartment and improves
access to the engine and fuel
system. |
|
 |
|
|
| Also,
it permits emptying of the dust cup
in severe dusty conditions. |
|
|
| Throttle
Body |
| The
throttle body under the carburetor
has been eliminated: this change
prevents flooding on gasoline
tractors and prevents operators from
bypassing the governor. |
| |
| New
Governor Actuator
|
| The
separate electronic governor
actuator and linkage has been
replaced with a new system, which
connects directly to the carburetor
throttle shaft. |
|
|
| In
addition, the LPG carburetor has
been replaced with a side inlet
unit, permitting direct connection
to the air cleaner. |
|
|
| Aluminized
heavier muffler and pipes |
| These
changes increase exhaust system life
and eliminate the need to remove the
muffler when removing the drive axle
assembly. |
|
|
|
|
| New
Rear Spring and Spring Mount: |
|
|
|
|
| Improvements
include: |
- Higher
capacity leaf spring
- New
mounting pad welded to frame:
heavy plate replaces tapped
block eliminating the risk of a
twisted off bolt
- A
heavy clamp plate replaces the
two clamping bars
- 1/2
inch bolts replace 3/8 inch
capscrews
- A
spring pad has been added to the
axle assembly to reduce loads on
the end of the spring
|
| |
|
|
| Torque
brace on drive axle |
| To
prevent axle housing damage from
severe braking situations, a brace
has been installed on the axle
housing to transfer braking torque
to the axle carrier (parts
are available for field
retrofit).
|
|
|
|
|
| Vented
rear wheels |
| Large
openings have been added to the rear
wheel disk to provide ventilation to
the brakes. Tests show that
this change reduces brake
temperatures by over 300 degrees,
preventing heat damage to the
brakes. |
|
|
| Heavier
drive axles |
| The
28 tooth spline drive axles have
been replaced with larger
diameter 31 tooth spline axles
(using a new high strength heat
treated forging) for a 100 %
increase in strength. |
| |
|
|
| Saginaw
steering gear |
| This
power boosted roller sector gear
eliminates a steering cylinder,
hoses, filter and the need to bleed
the steering system. The current
version of the gear almost
eliminates steering effort. |
|
|
| Transmission
shift lock |
| This
device prevents power shifting
through neutral from reverse to
forward to prevent transmission
damage due to “horseplay”. |
|
|
| Parking
brake/Transmission interlock |
| A
switch on the parking brake prevents
driving the tractor with the parking
brake applied to reduce wear
on the brakes. If the operator
attempts to drive the tractor with
the parking brake engaged, the
engine will not run above idle. |
|
|
| One
piece galvanized thick wall
transmission cooler lines |
| These
reduce leakage and corrosion damage. |
|
|
| Power
steering pressure hoses
|
| Power
steering pressure hoses have been
replaced with a galvanized steel
line. This cleans up clutter
on top of the engine and eliminates
hose failures. |
|
|
| Power
steering pump mount revised
|
| The
new mounting eliminates the belt
idler: this increase belt life by
over 300%. |
|
|
| Dynamometer
testing |
| Every
tractor shipped since January, 1996
has been tested for drawbar pull and
travel speeds on a chassis
dynamometer up to 3500 pounds of
drawbar pull. |
| This
assures that problems such as leaks,
overheating, and lack of performance
are discovered and solved before the
customer receives the tractor. |
|
|
| Effect
of improvements |
| GT
3000A tractors manufactured with
these improvements have been
operating in severe applications
with significantly less down time
and reduced operating costs. |
