Model Siena K5.60 AR - Tractor



Isodiametric tractors, monodirectional or reversible, with central articulation. 48 hp. The Siena K5.60 AR are specialized tractors designed to be used in extremely tight spaces: row crops, vineyards, orchards, greenhouses and nursery gardens as well as all the maintenance work, in both summer and winter, typically done by local municipalities. Thanks to the isodiametric wheels and steering with hydrostatic drive acting on the central articulation, the best qualities of the Siena K5.60 AR is its agility and manoeuvrability.

The reversible driving position (optional) allows to operate practically and rationally both with towed and front attachments.

The Siena K60 are mounting a 4-cylinder, Kubota engine with direct injection developing 48 horsepower.

The engine is provided with a counter-rotating mass now absolutely necessary for cantilever engine machine applications in order to avoid annoying vibrations and redundant noise inside the cabin.

The transmission of Siena K60 is fitted with the OS-FRAME chassis. 

The structure with cantilevered engine allows for a very low centre of gravity without sacrificing ground clearance. 

A 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 24-speed synchronised gearbox (12 FWD + 12 REV) with synchronized reverser allows for optimal use of the Siena K60, fuel economy and a better quality of work.

The 'Long Life' clutch is multidisc in oil bath and requires no maintenance.

The Siena K60 are equipped with planetary gear axles to minimize wheelbase of the tractor and increase its manoeuvrability.

The machine has a permanent 4-wheel drive.

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 540/750 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 equipments.

The hydraulic system consists of a double circuit with two independent pumps: one of 22,1 l/min dedicated to the lift and distributors, the other of 16,8 l/min dedicated to the hydroguide and electro-hydraulic control. As optional a 33,1 l/min oversize pump with heat stabilizer is available. 

A joy stick with electronic control, placed on the right arm rest of the operator, is used to control both the hydraulic system and the rear lift with a single device.

The braking system with multi disc wet brakes, act on the rear transmission.
Front and rear differential lock, electro-hydraulically controlled, allows the tractor to be always in traction.
The roll-bar and the safety belts on the seat protect the operator.

The driving position is custom-fitted on the driver with ergonomic controls placed to be easily found and activated by the operator.
The hydrostatic steering ensures maximum maneuverability and low turning radii.
The steering wheel and the seat are adjustable according to the operator’s physical structure. The digital display guarantees the total control of the unit.
In the reversible version the driving module is mounted on silent-block absorbing vibrations and noise for a better comfort.
A few seconds are required to rotate by 180° the seat, the steering wheel and the console so that the operator may work having the equipment in front of him and constantly be able to control the operations.

Available in Lusso and Comfort  versions with air conditioning, the Siena K60 cabs have 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.
The structure is mounted on a suspended platform completely independent from the chassis of the tractor in order to reduce noise and vibrations. 
The large windows improve the driver's view when operating in both traditional and reverse driving position.
