Hydro-pneumatic subsoiler Skat S1
S1 hydro-pneumatic subsoiler, professional machine available with two franter rollers with mechanical or hydraulic adjustment. Constructed in high-tensile steel and available in 3 different working widths of 2.5 - 3 - 3.5 m, it is ideal for tractors from 120 to 250 HP.

Features
- 1. "CRAKER”: disegned for compact stoneless soils. When operating in rocky soils, the legs of the hydro-pneumatic system SKAT provide high elasticity granting a longer operative life of the implement and less stresses for the tractor.
- 2. “ROCK”: with reinforced share, ensuring longer life and increased strength on stony soils. Special angle design to prevent the dragging of stones on the surface.
Alpego introduces an innovative ultra-fast ploughshare and accessory replacement system. With ALFAST, all you need is a hammer. No need to remove pins or screws.
The patented system consists of a clip which is moved along the shaft to free or lock the accessory on the shank.
The TROFEO ploughshares have an exclusive design, a variable thickness and a heavy-duty tip with a structure made of a special forged steel, to improve the performance.
The system, comprising a nitrogen accumulator with regulator valve and a series of cylinders, one on each shank, enables the shanks to absorb shocks and stresses and return to place gradually, avoiding damage to the frame structure.
In addition to the hydraulic NO STOP system, each shank is fitted with an easily replaceable shear bolt which breaks in case of excessive stresses to safeguard the machine’s structure.
High performance all-bolted frame. New side plate design for faster roller mounting. The high strength steel used provides the optimal trade-off between light weight and resistance.
Not only do the two Franter rollers perform a preliminary important superficial tillage of the soil and level it ideally, they also make the ensuing operations shorter and easier.
The double roller also contributes remarkably to efficiently mix in the organic residues.
M12 Mechanical FRANTER roller (Ø 140mm) ideal for light soils.
H12 Hydraulic FRANTER roller (Ø 140mm) ideal for light soils.
H22 Hydraulic FRANTER roller (Ø 194 mm) also ideal for heavy soils.
1) MODULAR PARALLELOGRAM KIT
Alpego has designed the modular parallelogram kit enabling quick changing of roller type.
With this accessory, the machine is extremely versatile and suitable for all conditions.
2) H50 HYDRAULIC FRANTER ROLLER
New H50 franter roller ideal for all soil types; floats over the lightest soils but crumbles heavy soils very effectively.
Hydraulic depth adjustment (Ø 220 mm)
3) G6 CAGE ROLLER
New GABBIA G6 roller, ideal for dry, light and medium-density soils. (Ø 550 mm)
4) DR6 DISC ROLLER
New DR6 DISC roller suitable for heavy soils. (Ø 600 mm)
New roller depth gauge clearly visible from the tractor driving seat. Available as standard on all hydraulically adjusted Franter rollers and on the modular parallelogram kit.
New angle gauge integrated in frame. Its internal and external positioning ensures visibility from the ground and from the driving seat.
New spare bolt holder integrated in frame.
Options

Clod-shattering fins ALFAST
Clod-shattering fins, the adjustable lateral fins achieve a better crumbling and turnover of the upper level of the soil.

ALFAST Dek system
The DEK system consists of the specific TROFEO DEK ploughshare coupled to the DEK fin. The coupled or single use of the two elements allows the operator to change operations in real time. The advantage of this modular system is that the two elements can be reset separately.

Telescopic clod-restricting side boards
New hydraulically retracted clod-restricting side boards, designed not to project when not in use, easily disabled when not required for simple jobs with no operator safety problems.

Pair of rear wheels

Reflective side tables and lights kit
New-design reflective side tables kit complete with LED lights installed above the rear roller.
