Silent blocks for VIGOLO disc harrows


Agricultural machinery

The agricultural machinery market is divided into two main categories: self-propelled or towed.
1. Self-propelled: vehicles equipped with an engine that move autonomously, such as tractors;
2. Towed: Machines that need another vehicle to enter into operation and include disc harrows, rotary harrows, plows, seeders and shredders.

Since the first years of production, the world of agricultural machinery has represented one of the most important markets for Athena. Athena through the variety of production possibilities and technical knowledge has established itself as a reference point for the development of:

  • Mechanical parts,
  • Technical products for specific application
  • Insulation systems



Vigolo was founded in 1963 and is a company that produces towed agricultural machines such as milling machines, fixed and folding rotary harrows, shredders, drills, and pointers.

Since 1969 Vigolo has started to develop its sales network abroad and the competition in the international market has contributed to the strengthening of quality standards and the study of technological innovations, often valued and protected by patents. The company stands out in the market for a strong propensity to apply new technologies in the field of agricultural mechanization.


The management of mechanical stresses

Disc harrows are among the agricultural machines towed and are used to carry out surface tillage of the soil.

The soil is rarely homogeneous, and these machines are faced with forces both longitudinally, but also latitudinally (due to the inclination of the discs), with problems of wear, failures, and possible compromise of the equipment. For this reason, it is necessary to insert supports that stabilize the system and allow to absorb and dissipate homogeneously the stresses applied upon the joints.


A special compound for our silent blocks

Disc harrow manufacturers have found in the SILENT BLOCK an essential component to dampen the forces in place (longitudinal and latitudinal) during soil tillage.

Due to this particular torsional spring, made of rubber for high performance, the tensions applied on the hinged joints are absorbed and the swivel joints can therefore carry out the work more easily and safely.


Another added value of this component is the reduction of breakdowns, less wear, and the drastic reduction of maintenance.


Our silent blocks have been subjected to assembly tests, usage tests in the early stages of starting the harrows and in the later phase of prolonged and continuous use by the customer, demonstrating a correct behavior resisting stress and failure.


Compared to similar components, Athena silent blocks guarantee:

  • + 20% of damping of latitudinal and longitudinal forces,
  • + 30% of tension absorption on the hinged joints,
  • - 50% of wear and time spent on maintenance.
