TTR 4400 HST II – Isodiametric Reversible Hydrostatic




TTR 4400 HST II – Isodiametric Reversible Hydrostatic Multi-Functional tractor


TTR 4400 HST II brings the hydrostatic transmission into the mid-power tractors category. With a silent 38 hp engine, this compact tractor fits a wide range of duties. From greencare to mowing, to urban and road maintenance, TTR is always the right choice.

The mix between hydrostatic transmission ACTIO™ chassis and reversible drive result in a first-choice multi-functional tractor. Along with the four-wheel drive and the low centre of gravity, these features deliver a stable, precise, multi-tasking machine.

The tractor works with precision on every soil, flat or steep, harsh or smooth.

Available also with air-conditioned cabTTR is available with many electric, hydraulic or comfort options: Front lifting system, seat with pneumatic suspension, mowing-collecting kit, are just some examples.

AC Full Chassis with Oscillation – cast iron full chassis hosting the tractor’s transmission. with a central articulated joint which allows a longitudinaloscillation up to 15°; this system allows the tractor to keep up with the soil’s sinuosity ensuring constant tractionand grip.


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.

Steering wheels

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

Hydrostatic transmission with hydraulic control; Mechanical selector with 3 speed range: low/normal/high; Continuous speed variator in both forward and reverse from 0-3.7, 0-7.4, 0-17 mph; Independent PTO with 2 speed: 540 and 1000 rpm; Front and rear differential lock; Disengaging drive wheels on rear axle; Speed-fix control.

EXG Extended Warranty

As a proof of its reliability, Antonio Carraro offers, in addition to its two-year standard warranty, an extension of warranty coverage up to three or four years, called EXG Maximum Protection.


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.
