Drawbar Control And Maintenance

We machine the main arm or drawbar in a single operation in a machining centre, eliminating dimensional errors. All structural components are made of ferritic matrix nodular cast iron, which offers excellent resistance to torso bending, allowing the part to resume its original geometry in an extreme overload situation thanks to its elasticity.
As for the wheel, tread and capper joints, significant improvements have been incorporated, such as a treated hub made of high-quality cemented and ground non-deformable steel with a hardness of more than 64 RC, which guarantees its durability.

The lubricant performs the following functions:

In addition, instead of placing them flush with the body, they are incorporated 5 millimetres into the interior, and a small-sized seal is housed but has enough capacity to stop the entry of dirt, water and pollutants. The assembly process includes permanent shaft lubrication that eliminates the need for a lubrication zerk, ensuring optimal performance and increased assembly durability.

It forms a layer between two metal surfaces, avoiding friction between metals.
Prevents oxidation of moving parts.
Where grease exists, dirt cannot enter (the worst enemy of bushings and bearings).

All its components must be greased and lubricated to ensure their proper functioning. Check that the zerks are working correctly and are not stuck or obstructed; if in doubt, replace it with a new one.
