Purpose and Design Features of the FN-2

The FN-2 rotary tiller is an active-type tillage implement designed for intensive soil crust pulverization, weed control, and seedbed preparation. The equipment belongs to the category of small-scale tractor attachments, compatible with tractors of traction class 0.2–0.4 (12 to 24 hp). Unlike passive disc harrows, the FN-2 utilizes rotating blades, providing deep loosening without turning the soil layer, thereby preserving the soil structure and moisture balance.

Drive and Working Components

The primary working assembly is a horizontal shaft equipped with L-shaped blades. Torque transmission from the tractor's power take-off (PTO) is carried out via a driveshaft and gearbox. The FN-2 gearbox features a gear ratio adapted for operation at a rated speed of 540 rpm, allowing the blades to achieve the optimal rotational speed required for effective pulverization of any soil type, including fields recently converted from fallow land.

Hydraulics and Attachment

The FN-2 is attached using the tractor's standard three-point linkage system. The design allows for adjustable working depth, ranging from 8 to 18 centimeters. The weight is balanced to avoid excessive load on the tractor's front axle, ensuring consistent penetration of working components even in compacted or heavy soils.

Applications in Agricultural Operations

The FN-2 tiller is effectively used for soil preparation before planting vegetables and grain crops on small farms and private plots. A key scenario is tilling fields infested with rhizomatous weeds. During operation, the blades chop the root system, preventing weed regrowth. Additionally, the unit is indispensable for incorporating green manure and organic fertilizers into the top layer of the soil.

Technical Specifications

• Working width: 1200 mm.
• Working depth: up to 180 mm.
• Number of blades: 24–26 pieces depending on the modification.
• Operating speed: 2–5 km/h.
• Total weight: 140–160 kg.

Maintenance and Reliability

Reliability is ensured by the simplicity of the gearbox and the accessibility of transmission components. Daily maintenance includes checking lubricant levels, inspecting blade bolt connections, and removing plant residue from the rotor shaft. Regular sharpening of the blades is crucial to reduce engine load and optimize fuel consumption during intensive field work.

Who Should Use This Equipment

The FN-2 model is ideal for compact tractor owners focused on intensive vegetable farming or gardening. It replaces multiple passes with a cultivator and harrow, providing high-quality pre-sowing preparation in a single pass. The unit offers excellent repairability, making it a cost-effective investment for small agricultural holdings with limited maintenance budgets.
