Thor-Transmission

Introduction

Performance, overall dimensions, manoeuvrability, comfort and safety: these are the features and the qualities that FERRARI technicians developed scrupulously for the Thor range tractors, qualities that really make the difference between a specialized FERRARI tractor and an ordinary tractor.

Thor RS, reversible isodiametric tractor with steered wheels available in the monodirectional or reversible versions, are the traditional version of the Thor range suitable for the widest variety of uses. Thanks to their qualities the Thor RS tractors are ideal for the wine-growing and fruit-growing sectors: the compact overall dimensions, the high power and the correct weight distribution on the axles with the machine under a working load, make these tractors unbeatable in vineyards and orchards. The gear ratios, with gears always progressive without overlaps, the OS-Frame transmissions and the double circuit hydraulics with independent pumps and a heat exchanger, create and guarantee the best performance in the category of the specialized tractors.

Engine

Three VM engines for the Thor EP series, able to get the power out of every drop of fuel.-VM D753 IE32.2 litre, in-line 3-cylinder turbo diesel. Producing 70 HP at 2.300 rpm thanks to the intercooler.-VM D754 TE33 litre, in-line 4 cylinder, turbo diesel. Developing 79 HP at 2.300 rpm.-VM D754 IE33 litre, in-line 4 cylinder, turbo diesel. Producing 91 HP at 2.300 rpm thanks to the intercooler.For these models, VM has developed the new EGR System placed inside the engine. The system recycles the exhaust gases which, opportunely mixed, return to the combustion chamber, drastically reducing the emissions of nitrogen oxide (NOx) and fuel consumption.

Max revs were kept to 2.300 rpm to reduce fuel consumption, noise and vibrations for fuel savings and greater comfort. Full power remains unchanged in any case: in fact, all the engines produce their peak torque between 1.000 and 1.800 rpm.

Transmission

MECHANICAL FLUID GEARS

The performance of an engine would be nothing without the best transmission. The new Sincro 32-speed transmission (16 AV + 16 RM) with synchronized reverser and helical gears offers the very best performance, improving the comfort and drivability of the vehicles. The logical sequence of the gears, without overlaps throughout the range, lets you select just the right gear for any particular situation for a more rational use of the vehicle, saving fuel and letting the engine work in its optimal range.

PERMANENT 4WD DRIVE

The four-wheel drive allows you to move rationally both on steep slopes and on uneven terrains. The electro-hydraulically controlled front and rear differentials always ensure the maximum traction to the tractors.

A UNIQUE TRANSMISSION SYSTEM

The new transmission comes with the OS-Frame which, with one single transmission shaft and one central joint, guarantees the maximum mechanical performance. The joint in the middle of the vehicles lets the front axle oscillate by up to 15° with respect to the rear, for excellent stability on slopes.

LONG-LIFE CLUTCH

The LONG-LIFE clutch is a multiple disc hydraulic clutch running in an oil bath. This, as well as improving the reliability, allows reducing the projecting part of the engine and reducing the length of the machines.

THE VERY BEST IN BRAKES AND MORE

The multiple disc brakes running in an oil bath guarantee perfect adherence to the ground, for safe braking in any conditions.

Driver

The driver’s environment on the Thor combines comfort, ergonomic qualities, functionality and safety in an absolutely original way. The driving seat and controls are made-to-measure for the driver: the controls are positioned ergonomically and intuitively and the steering column, as well as the comfortable seat, can be adjusted according to the build of the operator. In addition, in the reversible version of the Thor, the driving module (seat steering-wheel-dashboard) rotates in only 5 seconds practically and safely without any disconnections. The exclusive cabs have been made with attention to every detail, to guarantee the maximum comfort with the most pleasant living conditions. The large windows, as well as making access to the driving position easier, ensure excellent lateral and rear visibility. Air-conditioning and heating are guaranteed by an efficient system which, together with the total sound-proofing of the cab, contributes to creating an excellent working environment.

Hydraulic System

In a specialized tractor, the performance of the hydraulics is fundamental. The Thor has a double hydraulic circuit with independent pumps and a heat exchanger: the serial hydraulic pump has a flow rate of 31 lt/min. like the service one.

There are 5 standard rear distributors to connect equipment that requires high-capacity hydraulic supply, often used in vineyard cultivations. The Thor tractors are often used with tools on the lift with normal or quick-fit linkages, suitable for all kinds of equipment on the market. Supported by the hydraulic system, on request the tractors can be fitted with a controlled force and position system.

The Thor can also be equipped with a practical front lift, essential for combined use, supplied with four hydraulic outlets. For those who need to work with equipment that must adapt to uneven terrain by following dips or rises without damaging the surface, FERRARI has created for Thor RS a convenient hydraulic suspension with a nitrogen accumulator that optimizes the “load of the equipment on the ground”, applied to the third point hitch, for optimal performance on any kind of terrain.
