Interview Questions for Harvesting Machinery Operation

My experience operating combine harvesters spans over 15 years, encompassing a wide range of crops and conditions. I’ve operated various models, from older mechanical machines to modern GPS-guided combines. This experience includes everything from daily operation and maintenance to troubleshooting complex mechanical and electronic issues. For example, during one particularly challenging harvest, we experienced heavy rain leading to significant crop lodging. I had to adjust the combine settings multiple times to effectively harvest the crop while minimizing losses. My expertise also includes training newer operators, ensuring safe and efficient harvesting practices are followed.

Combine harvesters utilize different headers depending on the crop being harvested. The choice of header significantly impacts harvesting efficiency and yield. Here are some common types:

• Grain Headers: These are the most common type, designed for harvesting cereal grains like wheat, barley, oats, and rice. They feature a rotating reel that feeds the crop into the cutter bar, which separates the grain from the stalks.
• Corn Headers: Specifically designed for harvesting corn, these headers have rows of snapping rollers that remove the ears from the stalks. They are crucial for efficient corn harvest without damaging the grain.
• Soybean Headers: These headers are designed to harvest soybeans, often featuring a cutter bar with a special design to minimize losses of beans. They incorporate a system to manage and process the delicate soybean plants.
• Sunflower Headers: Used for sunflower harvesting, these headers have special cutting mechanisms to handle the large sunflower heads, ensuring minimal seed loss.
• Draper Headers: These are versatile headers suitable for various crops, including small grains and legumes. They use a gentler cutting action, minimizing crop damage compared to traditional cutter bars. They are particularly valuable in situations with lodging.

The selection of the appropriate header is paramount for optimal harvesting performance and minimizing crop loss. The wrong header for a specific crop can lead to significant yield reductions and increased operational costs.

Adjusting combine settings for varying crop conditions is crucial for maximizing yield and minimizing losses. The key parameters to adjust include:

• Concave Clearance: This determines the gap between the concave and rotor. For drier, more brittle crops, a smaller clearance is used; for wetter, softer crops, a larger clearance is needed to prevent damage.
• Rotor Speed: Higher rotor speeds are generally used for wetter crops to reduce grain damage. Lower speeds are suitable for drier crops to optimize threshing.
• Fan Speed: Controls the amount of airflow through the cleaning system. Higher fan speeds are used for wet conditions to remove chaff more effectively, but excessive speeds can lead to grain losses.
• Sieve Settings: Adjusts the size of the openings in the sieves to separate grain from unwanted material. These settings vary depending on crop type and seed size.

Experienced operators learn to make these adjustments based on visual observations (crop condition, amount of material entering the machine) and the combine’s monitoring systems (grain loss sensors, moisture content). For example, I once had to significantly increase concave clearance and reduce rotor speed when harvesting a rain-soaked wheat field to avoid shattering the grains. Fine-tuning these settings in real-time is critical to efficient and loss-free operation.

Pre-operational checks are essential for safe and efficient combine operation. These checks should be done meticulously before starting work each day. My standard checklist includes:
