90-185kW (120-250 HP)

With the ORSO model Maschio has introduced a new kind of bearing in its harrows: spherical roller bearings, providing greater strength than simple ball or conical roller bearings, combining strength and reliability to ease of maintenance.
This is suitable for continuous or heavy jobs, typical of farm contractors and tilling on rough terrain, with rocks and stones.
The roller bearings enable maintenance to be handled easily and quickly, permitting simple and economical operations typical of ball bearings. The market demand for increasingly high performance equipment but at the same time versatile and reliable led the Maschio Gaspardo R&D team to revise the HD power harrows range. The main changes have affected the structure of the rotors and transmission groups. Larger sections and always more resistant and reliable bearings allow to increase the loading power of up to 20%.

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.



PLUS stone deflectors Open Close


PLUS stone deflectors

“PLUS” stone deflectors are bolted to the second gear-trough layer and prevent damages to the rotors. Deflectors can be easily removed by a single bolt to improve soil flow among rotors!


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.

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

Number of rotors

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


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.


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.


Super sealing Open Close

Super sealing

The special seals are made with rubber and cellular polyurethane in order to guarantee a perfect long lasting sealing.

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.
