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 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 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 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.
