‘Powermaster’ is the apt name given to a trio of high-performance
four-wheel drive tractors that now lead the Landini tractor range.
With electronically controlled high pressure common rail fuel injection,
Dual Power releasing extra muscle for pto work and a transmission
giving the driver access to eight powershift speeds in each of
four ranges, the tractors are indeed masters of power.
“These are undoubtedly the most sophisticated tractors assembled
in Landini’s Fabbrico factory in Italy,” emphasises
Adrian Winnett of Landini UK. “They take our range to a new
level and will have great appeal among contractors, big grass farmers
and, in particular, arable growers.”
Engine
The distinctive-looking Powermaster tractors have latest-specification Iveco
NEF (New Engine Family) diesel engines beneath their shapely one-piece bonnets.
They are installed as stressed members with a reinforced sump to keep the tractors
as compact as possible and to make maximum use of under-bonnet space for an
efficient and easily accessible cooling package.
The 6.72-litre, 24-valve engines have common rail fuel injection
with full-feature electronic control, which not only helps them
run economically but also with exhaust emissions that meet the
next level (Euro 3a / US Tier 3) of emissions control regulations
in Europe.
Electronic functions include ‘cruise control’, which
sets a required engine speed that the fuel injection system will
maintain, within limits, as the load on the tractor fluctuates,
and driver-programmed working and headland engine speeds selected
by a rocker switch for easy manoeuvring.
In addition, the fuel injection control system’s Dual Power
feature automatically senses when the power take-off is operating
under load and adjusts the fuelling system to release additional
muscle.
For draft and transport operations, the Powermaster 180’s
engine develops 176hp but for pto work with the Dual Power function
activated it has up to 199hp available – a 23hp or 13% increase
with a similar increase in the amount of torque. The Powermaster
200 normally develops 199hp but gains up to 15hp (a 7.5% increase)
for an output of 214hp with Dual Power, while the Powermaster 220
gets a 14hp or 6.5% boost from 214hp to 228hp.
“This feature is a real boon for operators who use their
tractors with demanding pto implements, such as a forage harvester,
a power tiller or bed former,” says Tony Burgess, Landini
technical specialist. “It makes a real difference to the
tractor’s overall performance and output.”
Transmission
The Powermaster’s Autopowershift transmission complements
the engine performance characteristics with a large number of easily
accessible ratios, which encourages operators to fine-tune forward
speeds for whatever work they are doing.
“All transmission functions are operated using a fixed joystick
on the seat armrest,” explains Tony Burgess. “A single
rocker switch gives sequential shifting up and down through all
32 forward speeds while separate buttons are used to move straight
from one range to the next or engage automatic shifting between
the eight speeds in the fourth range.”
The Auto Roading auto-shift feature leaves the driver to concentrate
on the steering and brakes and is ‘intelligent’ in
that it responds to driving style and load. With a light touch
on the ‘throttle’ pedal, the gearbox up-shifts at an
economical 1800rpm but when faster acceleration is required or
a heavy load is involved, the transmission waits for full power
and torque output at 2200rpm before shifting to the next gear.
Forward and reverse are selected by a paddle lever to the left
of the steering wheel that also engages the optional transmission
lock. This characteristic Landini feature physically holds the
tractor in addition to the brakes for extra security when parked
on a slope, especially with a heavily-laden trailer or spreader
attached.
Bar axles are standard as part of the Powermaster’s heavy-duty
final drive assembly while up front the axle is carried on Landini’s
own electronically controlled suspension. This comprises a swinging
cradle assembly, two vertical cylinders and gas-filled hydraulic
accumulators to provide a compliant but controlled ride both on
the road and in the field. Front and rear differential locks are
engaged simultaneously with the press of a switch.
Hydraulics
The Powermaster is also well equipped in the hydraulics department.
Maximum output from the variable flow pump is 129-litre/min and
up to 106-litre/min is available at each of the six spool valves – three
manual with conventional lever operation and two electrically-operated.
“The electric valves are operated by a small joystick and
have dials for flow and timing adjustment set into the armrest,” notes
Tony Burgess. “These can be set-up to turn a plough at the
headland with just a flick of a lever.”
Cabin
These features are housed in a cab that gives operators a stylish
and spacious place to work, with plenty of storage options, a
fully upholstered buddy seat and first-class visibility fore
and aft and through fully-glazed doors that fill either side
of four-post structure.
Cab suspension for the first time on a Landini tractor works in
conjunction with the front axle suspension to give the operator
a more comfortable ride during long days in the seat.
Conclusion
The introduction of the Powermaster range signals significant redevelopment
of the Landini range at the upper end of the power market.
“The Powermaster’s combination of features and advanced
controls, and in particular the partnership of Iveco’s NEF
engine with our Autopowershift transmission, makes the tractor
a hard act to beat,” says Adrian Winnett. “We’re
looking forward to revealing the tractor publicly at the Cereals
Event and getting farmers’ reaction to what is the most advanced
Landini product to date.”
