Spading machines are tillage equipment largely appreciated in several working conditions and applications, such as:
- to work without any problem in extremely wet soil.
- to work up to a maximum working depth of 40 cm (60 cm models with rear sub-soilers).
- to remove the bottom soil hardpan.
- to partially lay underground crop residues without throwing the clods back completely.
- to limit soil erosion and also the wash away of light and steeply sloping soil, because the tilled soil is composed of medium size clods.
- Also it require low traction power thus it efﬁciently absorbs the tractor power.
In order to secure long life to the crank-mechanism, the frame which holds it must be extremely rigid and well designed. Our frames are machined after the welding, thus allowing an accurate control of the speciﬁcations which must be compliant to our design.
Very rigid crank mechanism
The crank-shaft, which drives the spades, is the heart of the spading machine. Each crank is coupled with a thick multi-splines shaft which guarantees the rigidity.

Special features to prevent soil jamming
The technical speciﬁcations of the machines have been taken into consideration the need to prevent soil jamming, especially in extremely wet or heavy conditions.
Double layer tillage (GR model)
GR model cannot be matched by any machine from competition: it allows
to till the soil up to 60 cm thanks to rear rippers which are hydraulically controlled. The traction strain is reduced to the minimum because the ﬁrst 40 cm layer of the soil is tilled by the spades.
Oil cooling kit (optional)
It avoids oil overheating when working conditions are difﬁcult, therefore it extend the life time of the transmission components.
All models suitable for tractors over 70 HP (Z90, G190 and GR190) are completely oil lubricated (both central gearbox and crank-drive mechanism).
This assures that the moving parts last longer because better lubricated than with standard grease lubrication system, and also allowing shorter labour maintenance (from daily check for grease lubrication to check every 50/60 working hours.
Thrust sealing to protect crank bearings (Z90, G190 and GR190)
Thrust sealing are usually used in crawlers of the industrial machines, and are composed of steel rings rotating each other and thus creating a vacuum which is water and dust proof.
Easy adjustment of working position
The working depth positions on the professional models (G190 and GR190)
can be easily adjusted hydraulically from the tractor cabin (optional). We can offer various wheels models to better hold the spading machines in any type of working condition.
Very wide range of models available suitable for any tractor horse power.
