Digging machine

The concept of the 'spading machine' was conceived in 1960 by the founders of Gramegna themselves.

Its operation, following the same principle as the hand spade, consists of alternately inserting the spades into the soil, tearing up the clods and throwing them backwards where an aileron or rake controls the degree of crushing and levelling of the surface.

Even today, the spading machine still offers important advantages over the use of other machines:

Features and advantages of our spading machines


The unique system of construction and machining of the frames allows for perfect alignment of the bed supports and high rigidity of the assembly. All connecting rod components are located in the upper part of the machine, so there is ample space between the connecting rods and the lower joints to prevent clogging during use in wet soil.


The gearboxes are designed entirely by us. The gearboxes are cast in high-strength spheroidal cast iron. The size and characteristics of the internal parts (bevel gear, gears, etc.) are designed to transmit high power without risk of breakage. Our gearboxes do not require heat exchangers.

Number of spades

Our spading machines have more spades for the same working width. This means a lower workload per unit, higher reliability and a better work result.


The construction technique of our machines (kinematics, balancing, phasing, etc.) allows our machines to absorb less power, minimise vibrations and stresses, improve work quality, and increase machine endurance.


All the lower joints of our spading machines (excluding Series 40 and 45) are equipped with special self-lubricating bushings for which no lubrication is required on the part of the user. This system guarantees perfect and constant lubrication of the joint components and maximum lifetime.


Many components of our machines (frame, 3-point linkage, skids, etc.) are bolted and not welded, allowing individual parts to be replaced and facilitating the disassembly of other parts for repair. Each spading element is completely independent of the others and can be dismantled and replaced.
