Sky Jump V95 Dualsteer
Tractors with front tires and rear rubber tracks, monodirectional, with double steering system. 91 HP
The Sky Jump is a specialized tractor with front tires and rear rubber tracks. This dual configuration provides the units the handling qualities of a classic tractor with tires as well as the stability and traction of a track.
As a matter of fact, the traction of the Sky Jump, depending on the terrain, can exceed by 60% the one of the tractors with tires and if used on steep slopes it has a higher side stability which allows the tractor to work in espalier rows, generally sloping downstream, while perfectly following its direction even if combined with heavy tractor-mounted attachments.
This mix-configuration of tires-tracks of the Sky Jump shows three advantages:
1. A remarkably reduced ground compaction thanks to the less pressure of the tracks on the ground in comparison with the pneumatic wheel;
2. Minimal damages of the ground between rows and when steering at the end of the field in comparison with a machine equipped with iron tracks;
3. Homologation for road circulation and possibility to easily travel at 40 km/h. without spoiling the road surface.
Thanks to the unique dual steering system Dualsteer® acting on the front wheels and on the central articulation, the Sky Jump has a great maneuverability equal to its brothers on pneumatic wheels, as it can reach a steering angle of 60° with very limited steering radius.
These features, combined with the short wheelbase and low center of gravity, make the Sky Jump the ideal machine for working in rows and crops on steep slopes where traction, stability, maneuverability and safety are the essential requirements.
The Sky Jump is equipped with a 4-cylinder, VM Turbo Intercooler engine developing 91 HP with EGR System inside.
The decision to use a lower number of rpms, 2300 rpm/min was conceived to reduce consumption, noise level and vibrations, with the benefit of comfort.
|Model||Power KW/HP||Nominal speed (rpm)||No. of cylinders||Displacement (cm3)||Aspiration||Maximum torque (Nm/rpm)|
|Sky Jump||67 / 91||2300||4||2970||Turbo Intercooler||420 / 1000|
The Dualsteer® is a patented double steering system that combines the central articulation of the frame with the steering of the front wheels: this allows to realize a real steering angle equal to approximately 70°.
From the operational point of view the driver only needs to operate the steering wheel because the control of the engagement proportionality of the two devices, which act simultaneously, is guaranteed by a hydraulic circuit and by a specific system of mechanical connection of synchronization. The hydraulic circuit acts both on the steering cylinders of the central articulation and on the steering cylinders of the front wheels while the connection system guarantees the synchrony and the progressiveness of the steering.
The additional hydraulic cylinder on the central steering increases both the power steering with high accuracy at very low speeds also in presence of high load on the axles, both the direction and stability on road transfer at high speeds.
Transmission and gearbox
The Sky Jump is provided with OS-Frame transmission awarding lots of advantages:
- a unique transmission shaft moves both the gearbox main clutch and the PTO independent clutch, while assuring the best mechanical output;
- the joint in the middle of the machine lets the front axle oscillate up to 15° with respect to the rear axle, for excellent stability on slopes;
- the double-mass flywheel with long-travel torsional damper is highly capable to eliminate the engine cyclic irregularities and also to give more torque to the engine itself.
The 32-speed synchronised gearbox (16 FWD + 16 REV) with synchronized reverser always allows right gear selection for the tasks for which the tractor is intended to.
The ‘Long Life’ clutch is multidisc in oil bath with a proportional hydraulic control and Pro-Act System for maximum performance and comfort.
The Sky Jump is equipped with planetary gear on the front axle and with cascade reduction gears on the rear side to minimize wheelbase of the tractor and increase its manoeuvrability.
The 4-wheel drive has got an electro-hydraulically controlled disengagement of the front one.
PTO and hydraulic system
The rear PTO is independent from the gearbox and synchronized with all progress speeds. PTO can be engaged by an electro-hydraulic control, it has a speed of 540/540E rpm or, as optional, 540/1000 rpm. The clutch is multidisc in oil bath.
The solid rear hydraulic lift by rams (optional with position and draft control) relies on multi-purpose practical and versatile couplings to adapt quickly and easily to all marketed equipment.
As optional, it is also available a hydraulically controlled upper link and tie rod which allows adjusting the attachments from the drivers position, and a performing front lift which is necessary when using combined attachments.
The hydraulic system consists of a double circuit with two independent pumps and dedicated heat exchanger: the hydroguide pump has a flow rate of 28,5 l/min, like the one for the lift and distributors. As optional a 49 l/min oversize pump is available.
A joy stick with electronic control (optional), is used to control both the hydraulic system and the rear lift with a single device.
Active and passive safety
The braking system, with 4 multiple disc wet brakes, is assisted by an hydrostatic control acting as braking distributor which intervenes constantly and simultaneously on the 4 brakes when acting on the pedal.
Exclusive to the Sky Jump is the independent Brake-off parking brake that is automatically inserted when the engine is off. When the unit is operating, on the other hand, it is controlled with a practical button on the dashboard.
The electro-hydraulically controlled front and rear differential lock, simultaneously or rear only, assures the best traction on any type of grounds.
The special cab with integrated safety cell protects the operator.
The driving position with platform mounted on silent block is custom-fitted on the driver with ergonomic controls placed to be easily found and activated by the operator.
From the seat the operator enjoys a complete view both on the machine and on the attachments.
The digital display guarantees the total control of the unit.
The hydrostatic steering ensures maximum maneuverability and low turning radii.
The Sky Jump cab has been designed with the greatest care to even the smallest details to guarantee the inside comfort and not to damage the environment in which they operate.
Available in Compact version which allows limiting the height and improving the use of the machine under the foliage in the pergola vineyards or under covered scaffolding and greenhouses.
The cab with heating and air conditioning has the air ducts placed in the front of the cabin to have the best air-conditioning and visibility also at the rear of the machine.
The structure is mounted on silent block suspended platform completely independent from the chassis of the tractor in order to reduce noise and vibrations.
