Grada rotativa plegable hasta 8mt de trabajo para tractores de alta potencia con cojinetes de doble líneas de rodillos y orientables
En el mod. JUMBO, Maschio utiliza una nueva clase de cojinetes para gradas, orientables con rodillos, de forma que la resistencia es mayor que con los de bolas o de rodillos cónicos, aunando robustez y fi abilidad con sencillez de mantenimiento. Es adecuado para uso continuado y pesado, tipico en las empresas que prestan equipos y en los suelos dificiles, con presencia de rocas y piedras. Pensado para ofrecer las máximas prestaciones y al mismo tiempo reducir y simplifi car el mantenimiento, JUMBO, gracias a su robusto bastidor, se pliega ocupando sólo 2.2 m, para poder ser transportado cómodamente
por carretera.
La demanda del mercado para implementos agrícolas cada vez más prestacionales pero al mismo tiempo versátiles y fiables ha llevado el Dept I+D de Maschio Gaspardo a implementar la gama de gradas rotativas HD. Las modificas principales han interesado la estructuras de los rotores y de los grupos de transmisión. Secciones mayores y cojinetes cada vez más resistentes y fiables permiten aumentar las potencias de cargas de hasta el 20%.

QUICKFIT tine system allows the user to replace tines quickly with one turn of the QUICKFIT tool, this minimises downtime and increases safety.
The frame of new folding power harrows has been improved to be more resistant to heavy and continuative stresses. Hydraulic cylinders have an auto balancing system to control the depth of the rear roller and make sure it always runs level.
QUICKPLUS is a bolt on shield system. Assembling deflectors among the rotors-gear trough clearance, those prevents: stones, twines and debris colliding and wrapping on the rotors shafts. Remove deflectors is quick and easy to operate in no-stony conditions improving soil and residues flow.
Maschio’s basic rotor design is replicated throughout the range: tine shaft are made from a single casting of pressed steel. This confers rotors higher precision and durability comparing to alternative manufacturing.
25 cm spacing among the rotors gives Maschio Power Harrows more rotors than many other power harrows on the market today, it also lowers the horsepower requirement and most importantly leaves a finer seed bed.
Power harrow can be easily coupled with a seeding bar either with packer or rubber rollers.
Main gearbox is critically important to the machine, so it is made directly by Maschio Gaspardo to ensure consistency, strength and quality. Spare gears are available on machines to change rotation speed of tines.
Double skin structure (internal shell 6 mm, external 5 mm) increases strength, prevents torsion and protects the workings from damage
The ON-GRIP tines are ideal for working in hard uncultivated soils with crop residues. Due to the shape of the blades you get excellent mixing of soil, it also leaves a large proportion of the large course soil on the surface preventing the top layer of soil creating a water tight crust.
Tungsten coated tines are suitable for abrasive soils: standard dotation on Jumbo, they are available as optional on other models.
Our Heavy Duty folding harrows are equipped with a cooling fan in the side gearboxes.
Thanks to hardened gears, synthetic oil and the cooling system, the gearboxes achieve excellent performance even under the hardest working conditions of prolonged high temperatures.
The special design of seals, made of rubber and cellular polyurethane guarantees a perfect sealing and long durability.
The tine rotors are all positioned at different angles which allow the power harrow to gradually dig into the soil reducing the vibration transmitted to the tractor and reducing peak loads on the driveline resulting in smoother operation and less fuel consumption.
