This is an advanced, wide-working agricultural implement designed for final seedbed preparation in a single pass.
Its defining characteristic, “hydraulic folding,” refers to the machine’s ability to use hydraulic cylinders to fold its large side sections (wings) from a wide working position into a narrow transport position. This allows for safe and legal movement on public roads.
The primary goal of this implement is to turn plowed or subsoiled ground into a perfect seedbed, ready for planting. It is a secondary tillage (finishing) tool, not a deep primary tillage plow.
Seedbed Creation: It breaks down clods, levels the soil, and lightly firms the ground to ensure optimal germination conditions.
Efficiency: Due to its large working width (often 5, 6, 8 meters or more), it can prepare a large number of acres/hectares in a very short amount of time.
Transport Safety: The hydraulic folding function is essential. The operator, from the tractor cab, can reduce the machine’s width to under 3 or 3.5 meters in seconds, making it easy to maneuver between fields or on public roads.
A hydraulic folding cultivator is a complex machine that combines several tools into one frame:
Hydraulic Folding Frame: This is the main chassis. The side sections (wings) are connected to powerful hydraulic cylinders. When activated by the tractor’s hydraulics, these cylinders lift and fold the wings (either vertically or to the rear) for transport.
Leveling Bars: Usually located at the front, these break large clods and level the field’s initial high spots.
Spring Tines (S-Tines): These are the main working components. Arranged in multiple rows (usually 4 or 5), they vibrate intensely in the soil as the machine moves forward. This vibration loosens the soil and shatters clods.
Gauge Wheels: These are essential for maintaining a consistent, shallow working depth (e.g., 2-4 inches) across the entire width of the machine.
Rear Rollers / Crumblers: At the very back, there is a single or (more commonly) double set of rollers (e.g., bar, cage, or “crumbler” rollers). These provide the final finish: they crush the remaining clods and lightly firm (reconsolidate) the soil to conserve moisture and ensure good seed-to-soil contact.
Due to their large width and significant weight (from the robust frame, hydraulic cylinders, and multiple tools), these cultivators require high-horsepower tractors.
A 5-6 meter (16-20 ft) model typically requires a tractor of 140 – 200 HP.
Larger 8+ meter (26+ ft) models can easily require over 250 – 300 HP.
