TTR 4400 HST
Two faced, or many machines in one
The Series 30 TTR 4400 HST machines are hydrostatic, reversible and multifunctional. The machine-attachment combination can be set up in various operational trims with a high standard of specialisation, performing a whole range of maintenance operations in the city landscape: like tend parks, clean pedestrian precincts, cut grass on motorway embankments, maintain grassed areas in sports grounds and on golf courses, move earth and dig in nurseries and on construction sites and clear snow.
The speed and sheer agility of TTR 4400 HST in movement, its exceptional steering, its compact dimensions and low-noise operation make this a perfect machine for the civil sector. There are high comfort levels for the operator, along with ergonomics and safety, all guaranteeing high-yield work in every season of the year and in whatever climate.
RGS™: RevGuide System
This allows the drive direction to be inverted in a matter of seconds without having to disconnect anything by simply rotating the control consol, which supports the steering wheel, dashboard, controls and seat, through 180°. Due to the fact that the control consol’s centre of rotation coincides with the centre of the driver’s seat comfort and above all visibility over tools and equipment remains the same regardless of the drive direction. This system was designed for working with front, rear and top loaded, at times simultaneously, equipment with the aim of increasing the vehicle’s productivity. Once fitted with a variety of implements the TTR 4400 HST is able to change its working philosophy time and time again. Thanks to its productivity and versatility it is a vehicle that can be used in all conditions and in all seasons. Consequently running costs can be reduced and there is a quicker return on initial investment.
ADVANTAGES
· Unbeatable versatility
· Less operator stress
· Maximum visibility on frontal equipment
· Rapid return on investment thanks to the reduction of down times
ACTIO™: ANTONIO CARRARO full chassis with oscillation
ACTIO™ is the only system of chassis oscillation that minimises lateral shaking to the operator both on slopes and when overcoming obstacles due to the fact that the seat is positioned at the chassis’ centre of oscillation. Traditional tractors with supported engines distribute their weight evenly on both axles; with the equipment mounted they have between 60 and 70% of their weight concentrated on the rear axle. The consequence of this is an extremely unbalanced vehicle that often needs front ballasting and this in turn increases the pressure on the ground and the vehicle’s overall length. The TTR 4400 HST, thanks to its ACTIO™ chassis with its overhanging engine redistributes the total weight of the tractor - 60% on the front axle and 40% on the rear one. In this way by fitting equipment to the power lift there is an equal redistribution of the tractor and equipment’s total weight: 50% on the front and 50% on the rear. In other words, the TTR 4400 HST when appropriately fitted out acts as a single unit made up of two completely independent tractors of the same mass and dimension which oscillate independently of each other at 15°. Oscillation between the two parts occurs at the centre of the chassis so during the critical phase of overcoming an obstacle the two parts counterbalance each other thereby noticeably reducing lateral shaking and shifts in the vehicle’s centre of gravity.

STEERING SYSTEM
Thanks to the special feature of ACTIO™ i.e. full chassis with oscillation, the TTR 4400 HST is able to use extremely narrow steering angles due to the fact that the engine and the front axle form just one single unit. As a result with maximum steering and oscillation (30°) the wheels never touch the bonnet because these too move with the entire front part of the vehicle. The homokinetic joints of the front wheels are articulated which allows tighter angles without wheel locking and subsequent turf damage that entails. Gentle yet accurate steering is ensured even with low engine revs by the special “Load Sensing” valve, which guarantees the hydraulic priority to the steering system. The “Antishock” valve prevents possible shocks to the front wheels from being transferred to the steering wheel. In order to reduce the turning circle without damaging the ground it is possible to disengage the axle on the rear wheels (keeping the traction on the heavier axle) and use the steering brakes which in this case are controlled manually.
ADVANTAGES
· Extremely tight turning circle
· Drastic reduction in number of manoeuvres
· Greater accuracy of manoeuvre
· Greater productivity
· Less wear on tyres
· Less turf damage
· Less operator stress
The new Antonio Carraro mower range is dedicated to the most demanding green professionals.
Implements built according to the highest quality standard to guarantee the greatest reliability, profi tability and unprecedented strength.
MOWER WITH TT 1500 HDS TURBINE
The HDS (Heavy Duty Super) equipment is fitted with a reinforced frame with three extremely resistant blades that guarantee uniform cutting in all conditions. The cutting width of 150 cm is the same as the plate itself thus allowing perfect cutting right up to the edge. These mowers, even on difficult ground conditions such as long grass, are able to cut at a very high speed.
The TT 1500 HDS mower solves the two old problems associated with traditional mowers of cut regulation and blocking in a very new way.
The system allows the cutting height to be adjusted very quickly using a simple system of wheel height spacers. In sharp contrast to other mowers, the aspiration turbine is situated above the plate in a semi-central without lateral protrusions; this allows it to cut grass at the edges of pavements and kerbsides, both on its right and left sides.
For an easier maintenance the mower can be placed upright.
T 1500 HD MOWER WITH LATERAL DISCHARGER
The T 1500 HD mower with lateral discharger keeps the innovative characteristics of the model with the turbine: a rapid and innovative system that offers easy adjustment of the cutting height, a belt in kevlar that is resistant to the strongest loads, minimum noise thanks to the transmission’s helicoidal gears, capacity to cut grass at the edges of pavements and kerbsides.
MULCHING KIT
The kit consists of a series of special blades and baffles that allow for further chopping up of the grass. After which the fine “mulch” is uniformly distributed over the ground, providing excellent natural compost. This solution, apart from falling in line with a modern and ecological view of green care allows for the saving of time and expense connected with the collection, transport and disposal of grass cuttings.
The kit is available for the T 1500 HD model.

Highly reliable engines with a long work capacity
These are direct-injection diesel engines with cylinders in line, water cooled. They are low-noise and combustion is optimised, so they are ecological engines with low running costs. The excellent weight/power ratio makes operations faster in linear work, even with very heavy attachments.
The fuel tank of TTR 4400 HST is large enough to give it a longer work capacity than any other machine in its class.
Access to the engine compartment is facilitated by the hood that can be completely opened.

Space, ergonomics and comfort
Three words to describe the working environment provided by the TTR 4400 HST.
Space: because it is the only vehicle with 400 mm wide anti-slip lateral pedal and a160 mm central tunnel which doesn’t affect the optimal position of the driver’s seat in any way whatsoever. In addition all the pipes from the hydraulic system and the cables from the electrical system are kept together in one tunnel which renders the driver’s seat clean and safe.
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 double foot pedal for forward and reverse direction is positioned below the rotating the control consol and is equally accessible in both drive directions.
Comfort: because the driver’s seat 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. In both drive directions 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.
