Superspecialist Whether in mountain pastures, on hillsides & slopes, plains and tundra in Northern Europe, road embankments,
flood plains, in city parks and gardens, sports grounds ranging from football pitches, riding grounds and golf courses,
or any other sector which requires grass cutting and maintenance, the Ergit TTR is the specialist of its category.
in grass cutting and maintenance Its operational speed, precision of manoeuvrability and capacity for working on slopes is truly amazing: amongst Antonio
Carraro’s “flagships” the TTR is a superspecialised, “made to measure”, multifunctional, modern concept tractor.
Its compactness and unbeatable stability due to its width, low centre of gravity, four equal wheel drive with wide track
combined with an exceptionally powerful motor, constant traction and its markedly reduced turning circle means that
the TTR is capable of working on all types of terrain and can cope with all difficulties and unevenness in all conditions
and climates throughout the whole year.
Reversible drive, the multifunctional joystick with KE hydraulic suspension and the extraordinary visibility greatly
enhance its ergonomics make the task at hand easier by noticeably reducing the operator’s fatigue while increasing
average operational time with a consequent saving of time and energy.
The TTR can quickly and easily change a large number of tools and pieces of equipment thereby enabling it to carry
out a wide variety of tasks even beyond those for which it was originally designed.
It is an environmentally friendly tractor that it is silent and clean.
Multifunctional: Designed to satisfy the needs of those involved in the cutting and maintenance of grass, from haying to sports
grounds, the fact is that the TTR is also a multifunctional tractor capable of carrying out a range of activities:
tidying up, foraging, barn maintenance, farm maintenance, summer and winter road maintenance, forestry and
many tractors, one talent building site work to name but a few.
Modifying it is simple: the integrated system which is made up of power lift-hydraulic system-PTO allows for the
rapid exchange of the most useful tools and pieces of equipment on the front or rear or simultaneously on
both. If necessary different tyres can be fitted, the drive direction can be chosen via RGS™ the reversible drive
system and the TTR does the rest.
It is amazing to see it working to an extremely high standard in any type of environment and on every type of
terrain: the combination of exceptional agility and good engine power with equipment such as the fork lift, front
loader, side arm, snow blade, mower, trailer, cutting machine just to mention the most commonly used tools,
gives the operator, situation after situation, the sensation of having not one tractor but many.
ACTIO™ Full Chassis with Oscillation:
one feature, many positive points
The System known as ACTIO™ consists of a powerful,
steel section which forms an integral part of the axle,
which houses both a front and rear transmission and
has an articulated joint which allows for longitudinal
oscillation of a good 15 degrees.
Essentially with ACTIO™ the TTR acts as a single unit
made up of two completely independent tractors of the
same mass and dimension which oscillate independently
of each other following the contours and different
gradients of the terrain, thereby maintaining constant
stability and grip.
With its overhanging engine the total weight of the tractor
can be redistributed - 60% of its weight on the front axle
15° and 40% on the rear one. Ideal balance that becomes
perfect when rear equipment is fitted: 50% on the front
and 50% on the rear. A feature which is maintained
throughout the task at hand thanks to the KE hydraulic
The ACTIO™ system provides for the use of four large
equal wheel drive; the TTR has, final drive reduction
gears on both axles, fitted with wide, low pressure tyres
that create minimum ground pressure at only 0.6 Kg/cmq,
which is a great advantage for grassed areas, especially
for those on slopes. The constant grip of the tyres with
the ground due to the longitudinal oscillation allows the
engine to ground all its power with consequent
advantages in terms of productivity and safety.
• Short wheel base and tight turning circle = maximum manoeuvrability on all types of terrain.
• Better distribution of weight = maximum grip, less wear and tear on tyres.
• Central, lower drive position = favours the adoption of RGS™ reversibility; the prolonged use of the tractor is less
stressful with respect to more traditional tractors; greater protection for the operator.
• Transmission inside the chassis = good ground clearance, lower centre of gravity; maximum stability even with
transverse speeds on steep slopes and in the case of loss of grip, sliding of the tractor avoids a roll over.
• Doubling of the total mass of the tractor and ample lateral oscillation = the parts of the tractor counterbalance
each other thereby maintaining maximum adherence of the tyres to the ground. A TRADITIONAL TRACTOR
• Possibility of being fitted with 4 large equal wheel drive = greater traction, greater floatation.
RGS™, RevGuide System: Steering:
5 seconds changes your life sensitive and at the ready
The TTR is a tractor with a short wheel base with accurate, ever ready steering
and despite its width has an extremely narrow steering circle which guarantees it
a great capacity for working on rocky terrain, terraces, basins and difficult
situations. The steering wheel with hydroguide is sensitive and respond quickly in
all situations: on slopes, with transverse speeds, on uneven ground and when
zigzaging between trees and bushes.
By disengaging the front axle and using the steering brakes the turning circle is
reduced to a minimum, this is improved further by the “superbend effect”:
the front wheel on the inside of the bend, due to the geometry of the steering
arms, independently increases its own steering angle thus eliminating any
problem regarding vehicle locking. The minimum internal turning circle is 1700
mm (67 in) while the external is 3000 mm (118 in).
With the RGS™ system the Ergit TTR inverts the drive direction in 5
seconds. It is sufficient to release the block on the driver seat to make
the monogroup, which consists of the seat-joystick-steering wheel-
dashboard-pedal board, rotate through 180 degrees.
The result is amazing: not only does it offer a different field of vision but
• Articulated homokinetic joints = tight steering without wheel locking;
also the tractor’s operational advantages increase, because with just

system and then the control solenoid valves thereby guaranteeing
that the steering is always power assisted.
• Rotating monogroup, which consists of the seat-joystick-
steering wheel-dashboard-pedal board = inversion of the
drive direction without disrupting any connection.
• Centre of rotation of the monogroup coincides with the
centre of the driver seat = constant visibility of
equipment in both drive directions.
• Clutch and brake pedals are suspended from the
monogroup and can be turned over and folded away
= no need for two sets of controls; more space available
for the operator in both drive positions; rotation effected
