• Grain Tank Capacity: The grain tank capacity will determine how long the harvester can operate before needing to be unloaded. Larger grain tanks can reduce downtime and increase overall efficiency.
• Unloading Rate: The unloading rate will determine how quickly the grain tank can be emptied. Faster unloading rates can reduce downtime and improve overall productivity.
• Weight and Dimensions: The weight and dimensions of the harvester will affect its maneuverability and transportability. Consider the size of your fields and the width of your roads when choosing a harvester.
• Technology and Features: Consider the technology and features that are important to you, such as GPS, yield monitoring, and automatic header height control. These features can help you optimize your harvesting performance and reduce operator fatigue.

Carefully consider these specifications when evaluating John Deere corn harvesters. By comparing the specs of different models, you can choose the one that best meets your needs and budget.
