Landini launches new high horsepower tractors

The tractors are powered by Iveco NEF 6.7-litre, 24 valve, common rail, and feature the semi-powershift transmission that is also used in McCormick's XTX tractors. According to Landini the engine is installed as a structural stressed block rather than mounted within chassis rails. With a reinforced sump, this is said to keep the tractor as compact as possible. The engine features a power-boost function that senses when the pto is operating under load and - by altering engine timing and fuel delivery - boosts power by a maximum of 13%.

Despite sharing a transmission with its sister tractor - the McCormick XTX - the control systems are claimed to be different. The gearbox is controlled from an armrest-mounted joy-stick which offers shifting through the 32 forward and 24 reverse speeds. Landini has also added an auto-shift function that will change gear at a pre-determined engine revs. This only operates in the top range as it is designed for transport work.

The firm also says that it has fitted a "kick down" function that is designed to operate much like an automatic car. Apparently if the driver is working in auto-shift mode, flooring the throttle will give extra engine revs that allow the tractor to accelerate faster, principally by raising the gear-shift threshold higher. The direction shuttle is controlled via a traditional steering column mounted lever which will also carry a parking lock on future models.

Front suspension is in the form of Landini's own system which uses a beam axle carried on a swinging cradle and two vertical hydraulic rams cushioned by gas-filled accumulator spheres. Service intervals on the engine and transmission are set at 500 hours and 1200 hours respectively. In the hydraulics department a 130-litre/min variable flow pump provides oil flow to the linkage and five spool-valves. Two of which are electro-proportional and are fitted with a flow timer.

Landini is determined that these tractors will help it raise its profile within the arable sector and is actively seeking dealers in the east of England.
