A new more powerful addition to the Landini four-cylinder tractor line-up made its UK debut on the AgriArgo stand at LAMMA 2011.
It is the first Landini tractor of this size to emulate the six-cylinder 7 Series models in providing two power ratings; and the ’120’ comes with uprated hydraulics and brakes to match its more capable performance.
"The Powermondial has been a very successful addition to the range, providing farmers with a more spacious cabin and higher-spec hydraulics and transmission than we offered previously," says Landini product specialist Eamon Howden. "The new ’120’ takes the range a further step forward in terms of power, performance and features."
The Perkins 1104D-E44TA four-cylinder diesel engine at the heart of the new Powermondial 120 has the same 4.4-litre capacity as the 102hp and 110hp models. But it uses a 16-valve cylinder head and high-pressure common rail fuel injection system, controlled electronically, to obtain new performance features.
"The Dual Power management system produces two distinct power curves," explains Eamon Howden. "For draft work, such as ploughing and cultivating, the engine serves up to 112hp. But for operations that put less engine torque through the transmission, the fuelling system is remapped to generate up to 121hp."
This 8% or 9hp increase in output, which gives the tractor performance equivalent to a more powerful and more expensive model, becomes available automatically whenever the tractor operates a pto-driven implement at 1000rpm or the driver engages the transmission’s top range for road travel.
"Another feature of the electronic management system for road travel is that the tractor can run at top speed with reduced engine revs," adds Mr Howden. "So, at 40kph the engine spins at just 1830rpm for a quieter, more economical drive."
Unlike the Powermondial 110 (102hp) and 115 (110hp), which are available in both Techno and better-equipped Top spec, the Powermondial 120 will be available only with the Top equipment package as befits its performance.
That means it will come with a 36 forward, 12 reverse speed transmission incorporating three shift-on-the-go powershift steps and a new shuttle modulation control, which allows the forward-reverse shift characteristics to be altered to suit driver preferences.
A bigger main pump gives the hydraulics system a boost. It raises total flow from 82- to 90-litres/min, while continuing to provide a dedicated 30-litres/min supply to the steering and ancillary systems.
A new spool valve installation at the rear gives better hose routing around the top link area and comes with three valves as standard but up to five as an option. Also, the Powermondial 120 gets ’power boosted’ brakes as standard, giving maximum braking effect with lighter pedal pressure.
