In this Acres of Insight blog, Gleaner combine specialists Robert Ross and Aaron Beyer explore the critical factors you should consider when selecting a combine, demonstrating how aligning combine size with your operation’s needs can improve productivity and keep costs in check.
Choosing the right combine for your farm isn’t just about getting the biggest machine with the most horsepower. While power and capacity are important, what really matters is finding a combine that fits the specific needs of your operation. From hitting your optimal harvest window to ensuring that your grain logistics can keep pace, the goal is to maximize efficiency and avoid overinvesting.
Factors Influencing Combine Size
When determining the right combine for your operation, it’s important to start with the basics: combine classification. Combines are typically categorized based on horsepower, which directly impacts how many acres per hour they can harvest. For example, a class VII combine is capable of harvesting approximately 3,000 acres within a 21-day window, making horsepower a key metric in gauging overall capacity.
However, it’s not just about the size of the combine. You also need to consider the size of your operation and how many acres need to be harvested within your available harvest window. The bigger the combine, the more supporting equipment you’ll need, such as trucks and grain carts, to handle the grain output. If the logistics of moving grain from the field can’t keep up with the combine’s capacity, a larger machine might lead to inefficiencies, rather than boosting productivity. Ensuring that your operation can fully utilize the machine’s capabilities is important in making the right decision.
Maximizing Efficiency Within Your Harvest Window
One of the most critical factors when selecting a combine is the harvest window — the limited time frame you have to bring in your crops before weather or crop conditions deteriorate. Missing this window can lead to reduced yields or crop loss due to factors like early frost or over-maturity. The right combine allows you to harvest efficiently within this window, ensuring your crops are taken off on time.
However, balancing the need to hit your harvest window with cost considerations is key. While a larger, more powerful combine can potentially harvest crops faster, it also comes with higher operating and ownership costs. The goal is to find a machine that allows you to complete your harvest reliably within your time frame, without overspending on capacity you won’t fully utilize.
Overcoming Bottlenecks in the Harvest Process
No matter how powerful or fast a combine is, its efficiency is limited by how quickly you can move grain. A common bottleneck in harvesting operations is the logistics of transporting grain from the combine to storage. If the grain can't be moved fast enough, even the most advanced combine will end up sitting idle, wasting both time and money.
To avoid this, it’s essential to ensure your supporting equipment, like trucks, grain carts, and operators, can keep pace with the combine. A combine capable of harvesting thousands of bushels per hour is only as effective as the system supporting it. For example, if you can’t move grain away from the field quickly enough, your investment in a larger, faster machine won’t pay off.
The Cost of Over-Sizing
While it may seem logical to invest in a larger combine to increase harvest speed, bigger machines come with bigger costs. A larger combine not only requires a higher upfront investment but can also lead to increased fuel consumption and maintenance expenses. These costs add up over the life of the machine, and if your operation isn’t fully utilizing the capacity, the return on investment may not be worth it.
Bigger doesn’t always mean better if it’s not fully utilized. For example, moving up just one combine class can cost an additional $250,000, but may only save you a few extra days during the harvest season. This makes it crucial to weigh the financial trade-offs.
Questions to Ask Before Choosing a Combine
Before making a decision on a combine, evaluate your farm’s needs and limitations. Here are some key questions to guide your decision-making process:
1. What are your harvest expectations?
How many acres do you need to harvest each day and how quickly do you need to get the job done?
2. What is your available harvest window?
How much time do you typically have to complete your harvest? If your window is short due to weather or crop maturity, you might need a combine with more capacity. If your window is more flexible, a larger combine might not be necessary.
3. How far are your fields from storage or grain handling facilities?
What is the distance between your fields and storage or processing locations? This will affect how efficiently you can transport grain.
4. Do your logistics match your combine’s capacity?
Can your grain handling system keep up with the output of a larger combine, or will bottlenecks slow down the process?
5. What is your budget, and how much are you willing to invest?
Does your budget allow for a larger combine, and will it deliver a return on investment? Larger combines require a higher financial investment. Consider not only the initial cost but also the long-term expenses for maintenance, fuel, and labor.
Choosing the right combine is about ensuring your equipment aligns with your farm’s size, logistical setup, and harvesting needs. By matching combine capacity to your operation, you can maximize efficiency, reduce costs, and ensure your grain is harvested within the optimal window.
