front linkage FS-4

Since more than 35 years Hauer develops and produces front linkages. They form the basis for the front linkage series “FS-4”. It impresses thorugh a robust construction, excellent lifting forces, high reliability and universal applicability.

The „FS-4“ is available in two variants: a fixed screwed version and a parkable variant



FS-4 fixed screwed

FS-4 parkable

construction type

The front linkage “FS-4” consists of 2 components: the front linkage and the coupling brackets. Through this separation in construction it is possible to offer two possibilities: One with the coupling brackets – a fixed screwed version and a parkable variant. With this second possibility the front linkage is mounted on the coupling brackets with big dimensioned bolts. Therefore it can be demounted easily with parking props. Consequently the front linkage can be used on a second tractor. Then only the coupling brackets and hydraulic hoses are required. The construction of the coupling brackets reaches up to the clutch housing of the machine.

One attachment part for using two products – an innovative and economical solution!

An additional advantage: The inclined lower control arms are situated closely to the front linkage during folding-up. Because of this, the mounted front loader can be lowered without any obstruction and there is free sight to the front.

The coupling brackets for the front linkage are identical to those of the previous series FS-3.
