The strength of a heavy-duty cast iron chassis helps the latest Landini 7 Series six-cylinder tractors cope with the stresses and strains of operating heavy grassland and arable implements front and rear.
The new range combines into one line-up six models derived from the 145-162hp Powermax and 180-225hp Powermaster. Engine power and torque outputs, and hydraulics performance, continue as before – but there is a new addition to the range.
The 7-185 model’s 6.7-litre engine produces up to 171hp for draft work and 183hp when the power boost automatically increases output for transport and PTO operations.
As well as the cast chassis, all Landini 7 Series tractors now use the same Vanesco electronic system for precision control of the three-point linkage; and instead of just one control specification there are now three different combinations of transmission and spool valve controls to suit budgets and preferences.
“This is a tough tractor made even tougher with the introduction of the chassis,” Landini product specialist Eamon Howden said. “It not only adds backbone strength, but also helps isolate the cab from engine-generated noise and vibration.”
For maximum comfort, buyers can add hydro-pneumatic cab suspension, as well as independent front axle suspension that can improve heavy draft traction in the field.
The 6.7-litre, six-cylinder Fiat Powertrain engine is now carried on ISO mounts by the chassis instead of being part of the tractor’s load-bearing structure. Its power and torque characteristics encourage operators to work the engines at relatively low revs, resulting in good opportunities to save fuel.
“There’s plenty of low-end torque,” Mr Howden said. “So the PTO is geared to take advantage of that and operators should shift up on draft work to drive the revs down for maximum fuel and power efficiency.”
Maximum outputs for draft work increase by an average of 7.5 per cent across the range when the Power Management system automatically alters the fuelling profile. This feature is triggered when torque is detected at the PTO shaft and on the 7-145 to 7-190 models when the top range is selected for transport.
With the Landini Autopowershift transmission providing eight button-shift speeds in each range, plus button range shifting on electronic versions, operators can make best use of these power and torque characteristics.
“Most operators have to make do with just three or four powershifts,” Mr Howden said. “Just imagine how easy it is to keep the engine spinning at the right speed for peak performance and/or economy when you can easily flick between eight speeds under load.”
