DRAGO DC Power Harrow 80-150hp

The DRAGO DC Power Harrow is designed to suit small to medium size farms, with tractors ranging from 80 - 150 hp.

It's light weight but very sturdy due to the strength built into the design of the machine. It also has a large range of accessories and can be used in combination with a seed drill.

This makes the DRAGO DC a excellent choice for low to medium horse power tractors.

The DRAGO DC Power Harrow comes with a multi-speed 540/1000 rpm gearbox with interchangeable sets of gears.

The gearbox also has a spline at either end so the DRAGO DC Power Harrow can be used as either a rear or front mounted machine. Another PTO driven machine can be mounted and used behind this Power Harrow.

The DRAGO DC comes with a standard slip clutch PTO shaft (1" 3/8 6 spline tractor side yoke).

Cat II three point swinging hitches allow the machine to be connected to the tractor with ease and prevent heavy stresses being applied to the power harrow and tractor when working on undulating ground.

The DRAGO DC utilises a simple pin system to control the depth as standard. Hydraulic depth control is available as an option.

25cm spacing between the rotors give Maschio Power Harrows more rotors than many other power harrows on the market today, it also lowers the horse power requirement and most importantly leaves a finer tilth.

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 image above shows the strength that is built into the Maschio power harrow transmission trough. It has been put through rigorous testing with extreme loads to ensure it’s one of the strongest on the market.    

The DRAGO DC comes with a 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.

The POWER HARROW rollers adapt the machines for different types of soil and different requirements of seed bed preparation. Three types are available on the DRAGO DC - cage roller, packer roller and guttler roller.

Cage Roller - Ø370mm & Ø450mm

Works well on medium soil types and in low moisture conditions creating a good seed bed.

Packer Roller - Ø450mm & 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.

Guttler Roller - Ø450mm

The acrylic/special cast Guttler roller is the ideal solution for reducing weight and yet still aggressively cultivating the soil. It also concentrates consolidation in line with drill coulters and stays clean in tacky conditions.

Rear Roller Bearings

Strength is designed in to the build of each type of roller and the end bearings are protected by their casings whilst grease nipples are positioned out of harm's way.

Levelling Bar

The levelling bars on all models are mounted on the rear roller, this ensures that the levelling bar does not have to be altered every time the power harrow is adjusted for depth. The adjustment of the levelling bar allows the operator to ensure an even 'bed' of soil is presented to the rear roller for consolidation giving a consistent finish behind the power harrow. The levelling bar can also be used to keep soil, particularly clods, in the rotor area so that it is broken down to a finer particle size before passing underneath the bar and roller.

Tungsten Scrapers

Adjustable 'Long Life' Tungsten scrapers are fitted to all packer rollers and rubber rollers, they are positioned low, close to the soil at the rear of the roller ensuring soil does not build up into large clumps before being cleaned off.

The Quick Match system allows quick and easy attachment of the Maschio Power Harrow to the seed drill using a 3 point linkage, the drill and power harrow combination can be detached quickly and safely to use the harrow alone.

The Quick match system uses plastic buffer rollers to fix the drill to the power harrow and transfer the weight of the drill to the power harrow roller only, preventing damage to the machine on rough and stony ground.

With the drill locked into position on the power harrows roller, the harrow and drill can float independently ensuring the drill seeds at a constant depth even on very uneven land.

All Maschio tines are produced in Italy by Maschio and are made from high quality Boron tempered steel to provide reliability during work and long lasting performance. They are made on a robotic production line to guarantee that from the first to the last they are all of the finest quality.

 

Point options include:

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 rotor shaft is made from the highest quality carbon steel.

The 50mm rotor shaft gives added strength to the drive-line ensuring years of trouble free operation.

Maschio Power Harrows feature ‘heavy duty’ Labyrinth seals that prevent water and soil penetrating the rotor and gearbox, this also prevent oil escaping even after many seasons of use.

The Labyrinth seal guarantees a perfect seal allowing both bearings to be maintenance-free.

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.

Hardened gears submerged in oil transfer the power from the drive-line to the rotor tines.

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.
