The JUMBO RAPIDO PLUS is the flagship ULTRA HD model, the biggest, strongest and the best hydraulic folding range of power harrows. It is available in working widths of 6m, 7m and 8m yet still folds to 2.45m for easy and safe road transport. Suitable for the most extreme working conditions, primarily designed for contractors and large scale farmers working in heavy stony soils.
It comes as standard with a Multi-speed gearbox that is capable of transferring up to 450 hp, two sets of gears allowing the operator to change the rotor rpm to suit different working requirements, also standard with QUICKFIT tines and QUICKPLUS stone deflectors.
Utilises the heaver maschio design that includes double rail barrel bearings for the top and bottom of the rotor, new improved sealing systems, heavy duty gears and rotor just to name a few.
(You can find more information on the rotor specification in the FEATURES section on this page).

The JUMBO Power Harrow utilises a high power multi-speed gearboxes with the central gearbox using high strength helical gears,synthetic oil, built in oil coolers and hardened tempered gears. Capable of transmitting up to 450 hp. The JUMBO comes as standard with an extra set of gears allowing the user to alter the ratio and choose from either 350 rpm (standard: 16-22 gear set) or 300 rpm (15-24 gear set) at PTO 1000 rpm.
The JUMBO comes as standard with a central heavy duty P700 cam clutch PTO shaft (1" 3/8 21 spline tractor side) with two heavy duty side cam clutch PTO shafts.
Cat III and IV cast iron three point swinging hitches with cat IV reduction brushes allow the machine to be connected to the tractor with ease and also prevent heavy stresses when working on undulating ground.
25cm spacing between 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 titlh.
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.
The JUMBO Power Harrow uses the QUICKFIT tine system which allows the user to replace rotor tines quickly with one turn of the QUICKFIT tool, this minimises downtime and increases safety.
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.
The ON-GRIP tines can also be reversed to ON-SLIDE to work more like a standard power harrow blade and producing a finer tilth on the surface if required.
The image above shows the strength that is built into the Maschio power harrow transmission trough. It has been put through rigours testing with extreme loads to ensure it’s one of the strongest on the market.
On the JUMBO Power Harrow comes with the double skin transmission trough consisting of an inner 6mm steel trough and a 5mm outer skin, resulting in 11mm thickness in total.
The outer skin prevents stones and other objects damaging the inner skin and also gives a huge amount of strength to the main trough, which needs to cope with the power that is transmitted through the drive line and all the stresses and vibrations during work.
The extra long side guards prevent soil spilling from the side of the power harrow and leaving ridges and lines during work. The guards have built in spring dampeners that absorb the collisions from large stones preventing damage.
QUICKPLUS is a bolt on shield system which fits just infront of the rotor as it comes out of the transmission trough, preventing stones and debris colliding with the rotor and gearbox, in turn this helps to push the stones down to the lower cultivated area.
The floating system guarantees constant working depth on undulating ground giving the JUMBO Power Harrow 3% upward and 3% downwards movement on each wing. The float can be deactivated by using the hydraulic locking system from inside the tractor cab.
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.
The rotor splines are pressed into the shaft not machined, resulting in much stronger teeth and a more robust rotor shaft capable of transmitting higher torque.
The Maschio rotor system has a long shaft and reinforced bearings that are spaced as far apart as possible to cope with the twisting force and torque applied to the rotor.
The JUMBO Power Harrow uses a Cassette Seal below the top bearing sealing in a large quantity of grease allowing the top bearing to be maintenance free. The Cassette Seals are approximately ten times more resistant to dirt than standard sealing systems.
Maschio Power Harrows feature ‘heavy duty’ Labrynth seals that prevent water and soil penetrating the rotor and gearbox and also prevent oil escaping even after many seasons of use.
The Labrynth seal is specially designed for Maschio Power Harrows and is made from cellular polyurethane, this is the best material to guarantee a perfect seal and also provides excellent durability thanks to its wear and age resistance.
The JUMBO RAPIDO PLUS Power Harrow uses barrel roller bearings, each bearing has a double rail consisting of two rows of spherical or barrel bearings to cope with heavy workloads.
Main Advantages:
Long Life (Up to 30% longer life than traditional taper roller bearings)
High Load Capacity (Multi axial shock resistance)
Easy Maintenance (One of Maschio's main philosophies)
Each rotor has a separate cover which allows the bearings to be checked or changed without the need of completely removing the whole transmission trough cover.
Jumbo Rapido Plus Power Harrow - Tested To The Extreme
The JUMBO RAPIDO PLUS has gone through the most extreme testing in all conditions to guarantee the user many years of hassle free operation.
Electronic torque analysis.
Rotor seal system continuously run in a mud testing bath.
Rotor temperature monitoring.
Performace of the machine in extremely high and dense crop residues.
Heavy shock testing – Working the machine in stones over 350mm in diameter.
Overloading with extreme weights.
With the rigorous testing that all Maschio Power Harrows undergo, they have to be considered as one of the best power harrows available on the market today.

Rear Roller
Rear Roller Option
There is one option of rear roller:
Packer Roller - Ø500mm
The toothed Packer Roller works well breaking up any surface clods further and at the same leaving an excellent finish, ready for seeding. This roller also comes standard with tungsten coated scrapers.
Rear Roller Bearing
The long life oversized rear roller support consists of a bearing and roller support all in one unit and is manufactured this way so it has the strength to support the weight when the power harrow is used in combination with a seed drill. (models: DC and above)
The bearing and support has a relatively new greasing system that is situated in a protected section of the roller frame preventing damage from debris.
Tungsten Soil Scrapers
The scrapers are 4mm thick and are tungsten coated as standard, they are attached with a single bolt and giude for quick adjustment.
