In
grass cutting and maintenance
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. Its operational speed, precision
of maneuverability 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 and elevated 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 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.
It is an environmentally friendly tractor that it is silent and clean.

STEERING
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 guarantee's it a great capacity for working on rocky terrain, terraces,
basins and difficult situations. The steering wheel with hydroglide is
sensitive and responds quickly in all situations. |
The instrument board is amongst the best and is easy to read, there is
a screen which by day is anti-reflective and is back-lit by night, an
"on-off" information system (only the functions in use are on
the display) digital speedometer and rev counter for the PTO. All electrohydraulic
controls are push button and near to hand.
|
ENGINE
The TTR has a direct injection diesel engine which has the most advanced
combustion and injection systems. The range of capacities stands at 60,
64 and 87 HP. This produces extremely high quality four wheel drive right
from very low RPM.

| THE
EXTRA COMFORT CAB |
|
|
|
With
its attractive, light and transparent design, which is streamlined and
devoid of sharp edges, the "Extra Comfort" cab was specially
designed for the TTR to be able to work comfortably and safely in hot,
dusty environments such as when carrying out grass cutting, roadway maintenance.
Its integral comfort is complete, thanks to it spaciousness, perfect field
of vision in both directions, low noise and vibration levels and its excellent
heating and air conditioning systems. The efficiency profile of the "Extra
Comfort" is rendered even lighter by the curvature of the front and
rear windscreens which along with the totally glass door maximise the
operator's visibility and the light inside the cab. All the glass surfaces
can be opened, whilst the excellently distributed, forced ventilation
creates the effect of internal pressurisation. |

3
POINT LINKAGE
The TTR can use a vast number of different pieces of equipment that can
also be very large in size. The power lift is a vertical cylinder monogroup
with a 3 point hitch with quick release catches, its pump and hydraulic
system are autonomous. The rear position control lifter with an automatically
controlled 3 point hydropneumatic suspension hitch allows part of the
weight of the equipment to be loaded on the rear axle thereby considerably
increasing grip and stability
allowing it to work on extremely steep slopes safely.
The PTO clutch has electrohydraulic controls and progressive engagement
with a safety switch which prevents the accidental activation of the engine
when the PTO is on. The advantages are less engine load during engagement,
less stress to the PTO shaft, no effort required by the operator and reduced
running costs.
The
front auxiliary hydraulic system* with its
electronic control is made up of one simple distributor with flow rate
adjuster, an outlet for oil return and two double effect distributors.
This system is used with implements such as leaf cutters, pruning machines,
binding machines and shredders. |
 |
 
The System known as ACTIO™ consists of a powerful, steel section which
forms an integral part of the axle, which houses both front and rear transmissions
and has an articulated joint which allows for longitudinal oscillation of
a good 15 degrees. 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 terrain, thereby maintaining constant stability and grip. With
an overhanging engine the total weight of the tractor can be redistributed
- 60% of its weight on the front axle and 40% on the rear one. Ideal balance
that becomes perfect when rear equipment is fitted, 50% 0n the front axle
and 50% 0n the rear.

Transmission
& Gearbox
The TTR has a large, sensitive clutch which doesn't require any adjustment
due to the fact that the hydraulic engagement makes up the backlash which
comes about through usage. The gearbox with its helical-cut gears has
32 speeds, 16 forward and 16 reverse. In addition it has a synchronised
shuttle reverser which allows the drive direction to be inverted even
when the tractor is in motion.
The electrohydraulic engagement HI-LO system* which can be activated while the vehicle is loaded and at almost any RPM,
allows for a 20% reduction of set speeds and to therefore have 32+32 speeds.
Advantages are better use of power, reduction in the speed intervals of
one gear and another, constant operation in all situations and lower fuel
consumption.
