Oleo-Mac MH185R Lawn Mower

Engineering Balance of the Oleo-Mac MH185R

The heart of this cultivator is the Emak K 700 H engine with a displacement of 183 cm³. The choice of an Overhead Valve (OHV) engine is dictated by the need for stable operation under high loads. This design ensures more efficient heat dissipation and reduces fuel consumption compared to traditional side-valve systems. Combined with a cast-iron cylinder liner, this provides a significant increase in engine lifespan, which is critical when working in dusty field conditions.

Chain Transmission: Reliability in Torque Delivery

Unlike models using worm-gear reducers, the transmission of the Oleo-Mac MH185R is based on a chain drive housed in a reinforced casing. This solution effectively dampens shock loads when the tines hit stones or hard soil layers, protecting the crankshaft from damage. The inclusion of reverse gear is not just a convenience feature but a structural necessity: with a machine weight of 72 kg, maneuvering in narrow rows without reverse gear would make operation physically exhausting.

Working Width and Ergonomics

The unit features 85 cm wide tines, which can be narrowed to 60 cm if required. An important detail: lateral plant protection discs are included as standard. This eliminates the risk of damaging crops while weeding. The adjustable steering column allows for customization based on the operator's height and provides the ability to rotate the handles to the side, allowing you to walk on unplowed ground to avoid compacting the freshly tilled soil.

• Transmission: 1 forward speed + 1 reverse.
• Drive: Belt-driven with a tension pulley, ensuring smooth starting and clutch functionality.
• Maintenance: Access to main lubrication points and the air filter is designed for ease of use without specialized tools.
