(250-450 HP)

MASCHIO introduces in the model JUMBO the spherical roller bearings, a new concept to drastically increase performance compared to the traditional ball or tapered bearings. Suitable for the most intensive working conditions, it is designed to guarantee maximum performance with low downtime.
JUMBO, thanks to its folding frame, can be easily carried on the road, maintaining the transport width in 8 ft.

Cooling system Open Close

oil cooler

Cooling system

Side gearboxes are fitted with an integral fan, allowing the gearboxes to be completely self contained with no need for separate oil coolers, fans and extra pipe work routed around the machine that could be damaged and cause the gearbox to fail.

Blades holder Open Close

Power harrow shaft Maschio

Blades holder

Rotor shafts are processed by turning from a single tempered special Chrome Molybdenum high tensile steel and shaft is 2 ¼ in.

Low vibrations Open Close

Low vibrations

Rotors phasing (15°) makes tillage operation smooth with no vibrations.

Heavy-duty frame Open Close

Heavy-duty frame

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.

Why power harrow? Open Close


Why power harrow?

Outstanding soil refinement and best levelling action.

Optimal soil mixing: smaller clods on surface and perfect soil refinement in the lower layers good seed‐soil contact. Good water infiltration and no superficial crust. Less pulverization involves better soil structure and organic matter content on surface.

Higher working speed and depth than rotary tiller (4 vs 2/3 mph – max. 10‐12 vs. 8‐10 in.).

No hardpan formation.

Weed management solution for organic cropping systems (great weeder).

Ideal tool to mix chemicals on top layers.



XL side containing protections Open Close

side protection

XL side containing protections

The extra-long side protections prevent ridges from the side of the power harrow among the passes. The protections have built in spring dampeners that absorb the collisions from large stones preventing damages.

RAPIDO system Open Close

Rapido quick fit system

RAPIDO system

“RAPIDO” is a patented quick blades release system. A single central pin locks the tines in working position. With the special tool (standard on Rapido power harrows) is possible to spring-release the pin and remove manually the blades.


Reinforced trough Open Close

double skin trough

Reinforced trough

The gear casing is made of a 0.24 in. thick steel plate, in addition to that a 0.20 in. reinforcing plate is welded-on to give a box section and make the assembly very rigid and sturdy.



On-grip blades Open Close


On-grip blades

The ON-GRIP tines are ideal for working in hard no-till 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 blades are suitable for abrasive soils: standard dotation on Jumbo, they are available as optional on other models. 

Oversized long-lasting bearings Open Close

Oversized long-lasting bearings

Ball or barrel bearings instead of tapered ones: easy replacement with no need of pre-loading.


Gearbox Open Close

Large diameter bevel gears and curve tooth profile for larger contact surface and smoother transmission.

MULTI-SPEED gearbox allow to switch from 540 to 1000 rpm (rigid frame machines), and change rotor speed revolution!


Number of rotors Open Close

The 10 in. pitch among rotors improves soil refinement and ensures a uniform load on the tractor PTO splitting torque in more units.
