Siena K6.60 MT
Isodiametric tractors, reversible, with steering wheels configured in haymaking version. 48 HP
The Siena K6.60 MT are tractors with steering wheels made in the version for mowing fodder, especially in sloping areas.
The structure is characterized by a low centre of gravity for maximum stability on slopes without sacrificing the ground clearance for a rational flow of the mowed fodder under the machine.
The Dual Floating System
optimizes the load on the ground of the equipment applied to the third point, promoting its 'floating'.
Particular attention has been paid to the driver’s comfort: 4 post rops and approved cabins make for a practical and comfortable driving experience.
The Siena K60 MT are mounting a 4-cylinder, Kubota engine with direct injection developing 48 HP.
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.

Transmission and gearbox
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.
Active and passive safety
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.
4 post rops 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.
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.
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.
The clutch is multidisc in oil bath.
The solid rear hydraulic lift with accumulator for weight compensation HDR and Dual Floating system 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 30,3 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.
