The special feature of the TTR 4400 HST is the hydrostatic transmission which allows the speed to be continuously changed from 0 to 30 km/h and quickly inverts the direction of travel at any time using the balanced pedal.
Another peculiar feature of the TTR 4400 HST is the RGS ™Rev-Guide System, positioned on a rotating turret, which allows the direction of driving to be reversed in just a few seconds in order to work naturally both with equipment towed from behind, pushed in front or applied facing the direction of travel.
TTR 4400 HST II - Isodiametric reversible hydrostatic tractor
The underlying concept of the TTR 4400 HST is to replicate the characteristics of the top of the range AC tractors, but on a smaller scale. The strategic choice of direct injection propulsion units makes for reduced fuel consumption and top class performance. The TTR 4400, equipped with the classic ACTIO™ frame (Antonio Carraro’s integral oscillating frame) is distinguished by its hydrostatic transmission, low centre of gravity, reversible drive system and isodiametric driving wheels; all these features combine to create tractor capable of working on any type of terrain, on the flat, slopes or rugged terrain.
Antonio Carraro S.p.A. is directly committed to the continuous development and improvement of its website, with an in-house team in charge of graphics, content and coordination.

AC Full Chassis with Oscillation - cast iron full chassis hosting the tractor's transmission. with a central articulated joint which allows a longitudinal oscillation up to 15°; this system allows the tractor to keep up with the soil's sinuosity ensuring constant traction and grip. [read]
RGS™ Rev-Guide System, is the AC reversible driving system on a rotating turret which inverts the driving direction in just a few seconds in order to work efficiently with towed or frontal equipment. Simply turn the seat/steering wheel/dash/pedal assembly 180° for an identical, but reverse, driving direction. MORE
The short wheelbase and tight steering radius make the tractor extremely agile in crop rows. To further reduce the turning radius, the steering* brakes can be utilized, while accentuating the steering effect obtained thanks to the double-acting constant velocity joints.
Hydrostatic transmission with hydraulic control; Mechanical selector with 3 speed range: low/normal/high; Continuous speed variator in both forward and reverse from 0-6, 0-12, 0-28 km/h; Independent PTO with 2 speed: 540 and 1000 rpm; Front and rear differential lock; Disengaging drive wheels on rear axle; Speed-fix control.
Thanks to the ACTIO™ Chassis, the driving position coincides with the center of oscillation of the tractor. Sideways jerking and stress are very limited and operator fatigue is reduced, even after many hours. The on-board instrumentation is elegant, functional and intuitive: backlit anti-reflection screen for nighttime use; “on-off” information system; digital tachometer and PTO rev counter; and electro-hydraulic pushbutton controls.
Air suspension with load display - reclining backrest - lumbar support.
