Lemken Karat 9/300

Purpose and Design Features

The Lemken Karat 9 is a high-performance intensive cultivator designed for stubble cultivation at depths ranging from 5 to 30 centimeters. This machine belongs to the class of universal tillage tools capable of performing both shallow stubble peeling and deep non-inversion loosening. The frame design and the arrangement of the working tools ensure intensive mixing of crop residues with soil, promoting rapid decomposition and humus accumulation. The three-row layout of the tines guarantees obstruction-free passage of mass, preventing clogging even when working in fields with high moisture levels or large volumes of straw.

Working Tools and Working Depth

A key advantage of the Karat 9 is its tool-free quick-change system for share points. Farmers can choose between narrow shares for deep loosening (up to 30 cm) or wide wing shares for shallow cultivation and complete weed root undercutting. Due to the unique geometry of the share wings, the soil undergoes intensive crumbling, resulting in a fine-crumb seedbed structure in a single pass. Overload protection is available in two versions: shear bolts for lighter soils or a spring-loaded mechanism for rocky conditions, making the cultivator highly adaptive to any soil and climatic conditions.

Leveling and Consolidation Systems

Serrated leveling discs mounted on spring-loaded brackets are responsible for high-quality surface leveling. They effectively redistribute the soil flow, eliminating ridges and depressions left after the tines pass. The rear roller, available in a wide range of options (tube, bar, rubber-ring, or profile ring rollers), provides depth control and re-consolidation. This combination allows the operator to precisely maintain the set working parameter and ensures optimal seed-to-soil contact for subsequent planting operations.

Aggregation and Operational Characteristics

The Karat 9 model range includes both semi-mounted versions and trailed units with an integrated chassis. The hydraulic control system allows the operator to adjust the working depth and the pitch of the tools from the tractor cab while in motion. A high frame clearance (80 cm) prevents clogging, which is critical when working on high-stubble crops like corn. High-strength structural steel ensures a long service life under the intensive operating conditions of large agricultural enterprises.

Advantages Over Competitors

Unlike classic disc harrows, the Lemken Karat 9 provides better penetration into dense soil layers and superior organic matter mixing across the entire depth. The machine effectively breaks up plow pans, enhancing moisture permeability and soil aeration. The option to install fertilizer outlets directly behind the tines expands the machine's functionality, turning it into a multi-tasking implement for soil deep-loosening and fertilization simultaneously.

Maintenance and Reliability

The cultivator's design is highly serviceable. All lubrication points are easily accessible, and the modular tine system minimizes downtime during the season. Wear-resistant point alloys ensure long replacement intervals even when working in abrasive soil types. Lemken prioritizes component standardization, which simplifies the procurement of genuine spare parts. Investing in this equipment pays off through a reduction in the number of field passes and significant fuel savings while achieving high-quality soil preparation for planting.

Who Is It For

This unit is ideal for farms practicing Mini-Till or conventional tillage where high productivity and versatility are required. It serves as an effective tool for farmers who need equipment capable of handling any soil type — from light sandy loam to heavy chernozems. The high operating speed and superior surface preparation quality make the Karat 9 indispensable in tight agrotechnical windows, allowing for rapid moisture retention and field preparation for seeding.
