Folding rotary harrows

Strong points

Headstock structure

In order to guarantee the right strength and technical efficiency during use, Vigolo has developed various headstocks named SC-15, SC-20, SC-25 and SC-30. All variants of the top link frame are wellproportioned to the dimension and weight of the machine and are equipped with a safety locking system with an automatic hydraulic release.

Higher power transmission

All folding rotary harrow models are fitted as standard with high-efficiency, single-speed side gearboxes (A8, G7 and G8) and strong, reliable central gearboxes. The wide range of angle transmissions and gearboxes can satisfy every need and always ensure excellent and durable performance.


Vigolo supplies two types of damped endplates, one fixed (standard on the EPI and EPR models) and the other sliding (standard on the VPX, VPZ and VDB models, and optional on the others). The sliding version is especially suitable for working on rough terrain. It is possible to adjust the height of bothendplate models, and they have internal springs to ensure that they adapt to the terrain.

Adjustable levelling bar

The levelling bar, which is mounted on the roller as standard, has an easy-to-use mechanical system for height adjustment. A version with hydraulic adjustment is available as an option. The levelling bar was designed to remain oblique with respect to the tines, regardless of the roller position while working. This technical solution was adopted to reduce the impact violence when hitting stones and to prevent soil from building up while working. As an option, Vigolo also offers the levelling bar mounted on the machine.

Transmission with ball bearings and tapered bearings

The Vigolo EPI and EPR folding rotary harrows follow the traditional build philosophy, which uses a ball-bearing transmission system. Whereas, the VPX, VPZ and VDB models benefit from Vigolo’s experience, which has led to an evolution in the transmission concept of rotary harrows: transmission with opposing taper roller bearings was designed for use on high-power tractors and guarantees high resistance, even in the toughest working conditions.


The gears in the transmission body are cut and machined in Vigolo plants, and then undergo heat treatment to increase their surface hardness, while retaining their internal toughness. For this reason, the case-hardened gears mounted on Vigolo rotary harrows are extremely wear-resistant and ensure that the machines are highly reliable and durable. 

Rotor pitch

 The needs of the terrain to be worked determine which pitch (distance between rotors) is most suitable. The Vigolo range of folding rotary harrows covers the widest working needs: for better soil finishing, we recommend a short pitch (215 mm, EPI and VPX models), while for terrains with a high stone density, the long pitch (240 mm, EPR, VPZ and VDB models) has proved to be the winning choice.

Rotor phasing

 Rotor phasing, i.e. angled tooth distribution, was designed to reduce harrow vibrations during use, especially when working directly on compact terrain. On one hand, the evenness with which the harrow advances gives a homogeneous soil finish, and on the other, it limits the power required from the tractor. 

Ample space between the tine support and the transmission body

The large distance between the bottom of the transmission body and the rotor support reduces friction with the terrain while working. Thanks to this ample free space, any build-up of broken soil, or soil with a high stone density, slips off quickly and allows the harrow to advance with less effort.

Curved tines

 Vigolo’s special curved tines ensure that the harrow advances evenly and reduce vibrations during use. They prevent the soil from building up between the tools and are more effective at absorbing impacts with stones or banks of rock.

Stone deflectors

As standard, all Vigolo rotary harrows have stone deflectors at the most critical points, i.e. where the rotor motion brings the soil towards the working space of the harrow. When working on very stony terrain, we recommend adopting the optional built-in stone deflector, which covers the whole tine support.

2. Reinforced case-hardened gear
3. Ample distance between the tapered bearings
4. Pressed rotor support
5. Double hermetic oil seal
6. Reinforced case-hardened shaft

Vigolo rapid tine release
The innovative Made in Vigolo rapid tine release system makes it possible to change tools simply and quickly. This is done using a special key, which presses the locking pin to release the tine. This system, which was designed and made entirely by Vigolo engineers, does not require screws, bolts or other fastening accessories.

Floating system

Optionally, the fixed position of the Vigolo folding rotary harrow can be changed to floating by removing a mechanical stop. A hydraulic cylinder coupled with a chamber and plunger system allows the two machine bodies to take up different positions and adapt to the uneven or rough conformation of the terrain. 

Cardan shafts

Vigolo ensures the highest working safety by providing as a standard piece of equipment the main cardan shaft with a safety clutch and the lateral cardan shafts with safety shear bolts. In order to reach great results, even on demanding work conditions, Vigolo offers as an option the lateral cardan shafts with cam clutch fitting tractors up to 500 hp.
