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.
Central 1000 rpm gearbox with 3 tapered gears and rear PTO
Side gearbox pre-setted for 350 rpm
Standard pair of gears: 16-22
Rotor revolution PTO 1000 rpm: 350
Center PTO direct shaft P700 Heavy Duty
Side PTO shafts P600 Heavy Duty with cam clutch
Quick PTO shaft protection removal
Gear body with double trough structure
Bolt-on steel deflectors (PLUS)
Long dampened side protections
Quick blade release
Universal adjustable three point hitch III^ and IV^ cat.
Rear lights for transport (disassembled)
Hydraulic floating system
Hydraulic folding system
Safety hydraulic locks for transport
Transport width (folded): 8 ft.
2 blades per rotor
Pre-disposed for double pair of track eradicators
4 hydraulic roller side adjusters
Rear levelling bar with mechanical adjusters installed on the roller
Heavy duty barrel type bearings
Air cooled side gearboxes
Tungsten coated blades
Note: Version 8000 is not suitable for road transport (height when folded > 13¼ ft.)
Pair of track eradicators with pin adjustment and safety shear bolt
Pair of track eradicators with pin adjustment and safety spring
Hydraulically lifted transport trolley
Pair of gears for 395 rpm (15-24)
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.

XL side containing protections
The extra-long sideprotectionsprevent 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.
Oversized long-lasting bearingsOpenClose
Oversized long-lasting bearings
Ball or barrel bearings instead of tapered ones: easy replacement with no need of pre-loading.
Rotor shafts are processed by turning from a single tempered special Chrome Molybdenum high tensile steel and shaft is 2 ¼ in.
“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.
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!
Rotors phasing (15°) makes tillage operation smooth with no vibrations.
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.
Number of rotorsOpenClose
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.
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.
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.
The optional rear cart with pivoting wheels improves stability during road transport.
Why power harrow?OpenClose
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.
