SP 4400 HST

 
 
The SP 4400 HST (38hp) is an articulated hydrostatic, compact, super-handling tractor designed for the maintenance of pedestrian areas and city centres, the cleaning of roadways and pavements, snow clearance and the care of public parks and gardens. The SP can be fitted with front, top and rear fitting equipment whilst maintaining good working speeds. A convenient tray on the top of the bonnet makes the SP useful for material movement.
As far as mechanical innovations are concerned, the SP uses rear reduction gears that increase stability and handling, in addition to the hydraulically controlled brakes that guarantee decisive modular braking. The foot pedal hydraulically operates the hydrostatic transmission contributing to drive comfort in terms of practicality and safety. The JM joystick which controls the equipment is ergonomically positioned so that the operator has everything close to hand. In addition, for the tasks that require constantly controlled movement the operator can use the speed-fix device that holds a given speed during operation.

Space, ergonomics and comfort
Three words that describe the working environment provided by the SP 4400 HST.

Space: because despite its reduced external dimensions it provides the operator with a very relaxing drive position. Thanks to its reclining and height adjustable steering wheel and adjustable seat, accessibility and comfort are obtainable by taller than average drivers. In addition all the electrical cables and hydraulic pipes are kept together in one tunnel under the cab which renders the driver's seat clean and safe.
The cab is its selling point; the living space is bigger and it has 360° all round visibility. Its fabric, pneumatically sprung seat with standard head and armrests provides maximum drive comfort. The cab is fitted on silent-blocks that gently absorb vibrations. The vehicle with all of its (standard) details is a must for discerning and demanding customers; amongst which, there is the radio with a CD-MP3 player, the packed-lunch box and the air conditioning system along with a powerful headlight system and a 12V outlet.
Ergonomics: because all the most commonly used controls have been put in positions of easy access in order to reduce operator stress to a minimum even after many hours of use. The pedal for forward and reverse direction is positioned at the centre of the driver?s seat so that it can be easily reached but at the same time the necessary space to allow the operator to reach the brake pedal in the case of danger has been left.
Comfort: because the driver's seat with its pneumatic suspension and mounting platform are very close to the ground; all of the tractor's most important control instruments are positioned on the rotating the control consol and are instantly recognisable also thanks to the audible alarms. A glance is all that is necessary to check the temperature of the engine?s cooling liquid, its rev count, its speed or the state of clogging of the hydrostatic transmission?s filter system.
