PUMA

Etudié expressément pour travailler entre les files des vignobles et des vergers, le broyeur PUMA est la machine idéale pour le broyage de l’herbe et des sarments en tous genres.

Une série de dispositifs en fait une machine polyvalente et professionnelle.

Parmi ces dispositifs se démarquent les côtés sans angles vifs conçus pour ne pas endommager les plantes si elles devaient être touchées lors du travail.

Conjointement, la machine est étudiée pour sortir au maximum de la voie du tracteur.

La translation, présente dans la version à déplacement, s’effectue sur une barre chromée qui ne nécessite d’aucune lubrification.

D’autres éléments moins visibles, mais non sans importance, rendent le modèle PUMA un véritable hors classe dans sa catégorie.

Le premier élément de distinction est le “MARTEAU A DOUBLE TRANCHANT ”, brevet exclusif TIERRE, qui permet et une coupe de type horizontal et une de type vertical qui augmentent la capacité de concassage du broyeur.

Le second élément est le “ROTOR MULTIAGRESSIF” dont peut être équipé la machine : dans ce cas aussi, une réalisation exclusive TIERRE.
La particularité de ce rotor est de pouvoir monter le double d’outils normalement prévus pour un broyeur, ce qui augmente de façon significative la capacité de coupe de la machine qui se traduit en vitesse de travail majeure et meilleur absorption du terrain du produit broyé plus finement.

Le troisième élément est le double châssis en dotation présent sur la machine qui la rend particulièrement robuste et, donc, apte à affronter des élagages abondants et des terrains pierreux.
La dotation de série prévoit un boîtier à roue libre et un rouleau d’appui autonettoyant réglable en hauteur.
Disponible sur demande, un râteau postérieur permet de récolter les résidus pour les broyer encore plus finement.

Le broyeur modèle PUMA est disponible dans les versions : fixe, à déplacement mécanique ou hydraulique et réversible, toutes à attelage à trois points.

ADAPTIVE GEOMETRY

Impossible becomes simple.
A new concept of shredder able to change the shape of the cutting chamber up to 12 ways.
Each cutting configuration suits a different job that the machine can perform.

As a result, the same machine can be used in completely different working environments.
From mowing grass to pruning, or simply in the open field.
This is the TIERRE ADAPTIVE GEOMETRY patent, registered in 142 countries.

HAMMERS DOUBLE EDGED INNOVATIVE AND PATENTED

Main advantages:

  • double cutting surface both horizontally and vertically

  • low drag, less fuel consumption

  • greater impact resistance against rocks and stony bodies due to the particular shape of the neck

The hammers are mounted on a steel screw 12.9 with a diameter of 16 mm and are fixed to the rotor by means of supports made ​​of boron steel.

POSSIBILITY OF ASSEMBLE KNIVES IN DIFFERENTS SETTINGS

 

Main advantages:
• Knives Y, ideal for cutting and quickly discharge.

 

POSSIBILITY OF ASSEMBLE KNIVES IN DIFFERENTS SETTINGS

 

PUMA can mount a special rotor built thanks to the experience of Tierre in crushing.

This rotor has the feature to mount the double of the tools with respect to a normal shredder allowing it to pulverize the material to be cut.

It was also balanced electronically.

It has an anchor welded to the rotor that measures 10 cm. can not be accidentally disconnected, even in cases of accidental impacts with stones and this ensures maximum operator safety.

SUPPORT ROTOR AND BEARING

Rotor lateral supports are made of pressed steel,and then worked in order to obtain a single body without welding.

Supports are mounted on double ball bearings highly professional working with labyrinth which means double double lip seals.

DOUBLE-LAYER WALL

The wall of the machine is made of two sheets of 4mm.
These two sheets are placed one over the other, in contact, causing the machine twice robust with respect to shredders conventional with standard frame.
This crusher is indestructible also in the most extreme working conditions.
Resistant without the slightest difficulty in the presence of stones,(not oversized), shrubs, bushes and undergrowth with large branches.

2 rows of blades to the underside of the vehicle.
This means that everything that goes into the machine, that is, all that passes under it, is literally "Spray".
Suffice to say that the hub passes through the rows of blades over 30 revolutions per second.
Thus fragmentation has a capacity of 3 to 4 times higher compared with a conventional crusher.

To the eye the result is really impressive, especially on the ground of grass, branches and pruning residues. In a common crusher, hammer in rotation, when it hits a branch, is simply to throw back at high speed, sectioning at most once or twice in two smaller parts, in some cases even leave intact. In this machine, passes required by the hub within the counter, and the result is inevitably that is finely minced.

SERIES OF SUBSEQUENT CRAMPONS

 

You may request as optional.
rear bars serial (crampons). These are specific for shredding pruning or other crop residue. It is a fundamental tool, if we think there isn't a shredder on the market that can really grind effectively pruning, while fragments of medium or large size. We assume that any crusher is regulated in a working height of 3/4 cm. This makes the mower will leave intact the branches and debris lying on the ground, as the hub does not work sufficiently low. Should not be underestimated as the tractor wheels tend to flatten the ground or even bury these wastes.

Crampons perform a real action "clean" by extracting the ground and also raising waste buried by the wheels. Thus, no branch or waste will have the opportunity to escape this type of system. Each mace goes very close distance of each crampon. Thus, the branch will carry through crampons to be ground. To be passed then, as explained above, through the row of blades, resulting completely crushed. At the end of the work will be really difficult to find any residue from the still intact pruning at the base of the crusher!

MOUNTING:  Crampons should be adjusted to a height that allows you to work at ground level, placed on "free" position.In fact, it should swing vertically, so adapts to the irregularities and rough terrain thanks to its steep slope toward the back.
If the harpoon stumbles into some obstacle in the route, for example, a root or rock outcrop terrain, you can go back rise, thus avoiding bending.

HYDRAULIC SIDE SHIFT AND 3-POINT HITCH

Hydraulic side shift controlled by the piston.
Equipped with two hoses with quick couplings that are connected to the hydraulic connections on the tractor.

Again, the type of movement is the most solid and robust that you can find in the market. In fact, is divided into two tubes in chromed steel C45, means that even in case of severe accidental impact this will absolutely indestructible.

Connections to the tractor are very close to the machine.  This keeps the brush cutter in a position closer to the tractor, eliminating the risk of throwing stones towards the operator but above eliminates any problems caused because the machine is lifted, Thus, bringing the weight to the tractor, becomes overloaded to a lesser extent. This allows you to connect the machine even if high, also tractors with less mass and smaller weight.

TRANSMISSION

The gearbox is made by COMER and is bathed in oil, as well as the extension.

The lateral transmission has 4 belts mounted in pulleys that have been balanced electronically independently.

Pulleys electronically calibrated independently

REAR ROLLER

The rear roller support with adjustable height is 194 mm in diameter.

Undoubtedly the largest of its kind.

The rullo is mounted on an oscillating field bearing, which in turn is inserted in a special holder of galvanized steel.
The assembly is easily adjustable through holes for regulation height.

PAINTING AND SPECIAL ZINC

Paint of Tierre machines is done with epoxy powder.

All parts are painted separately before assembly in an oven at 180 ° C for 3 hours.
This system ensures the total resistance of the machine to atmospheric agents.
The parts are assembled with different faces that touch the paint with paint, ensuring the life of the machine.
The galvanized parts of the machine are provided by zinc bath at a temperature of 450 ° C
