When it comes to deciding on the appropriate size of tractor for your plowing needs, a number of factors come into play, such as the number of plow bottoms, soil type, and terrain. In this article, we shall examine what size tractor is suitable for a three-bottom plow. We shall also delve into the considerations that should inform such a decision.
The Rule of Thumb
One of the most crucial factors to consider when selecting a tractor for a three-bottom plow is the number of tractor horsepower required to pull each plow bottom. A good rule of thumb is that each bottom requires about ten horsepower. Therefore, a three-bottom plow needs a tractor with at least 30 horsepower. However, you may need more horsepower if you are working in high clay or heavily compacted soils.
Other Considerations
While horsepower is a primary consideration, there are other factors to take into account. These include the type of plow bottoms used, the speed at which you want to plow, and the terrain. For instance, mouldboard bottoms require more horsepower than chisel plow bottoms since they create a more significant soil disturbance. Similarly, rocky or hilly terrain may require more horsepower compared to flat land since it takes more power to pull the plow through the soil.
Matching Tractor and Plow Bottoms
Another critical consideration when deciding what size tractor to use for a three-bottom plow is matching the tractor's power with the plow bottom's design. Ensuring the plow has the correct drawbar pull allows it to achieve maximum plowing width without creating undue soil resistance. The drawbar should be level when in the raised position, and the plow should have decent 'pitch.' Pitch refers to the angle between the plow beam and line of draft and allows the plow to smoothly overcome soil resistance.
Conclusion
Choosing the right tractor for a three-bottom plow requires careful consideration of the various factors involved. You need to account for the type of soil, terrain, and the number and type of plow bottoms. As a general rule, a tractor with at least 30 horsepower is suitable. However, other considerations such as the tractor's drawbar capacity, plow pitch, and speed should also be taken into account. Overall, selecting the right tractor for your plowing needs is critical for efficient and effective farming.
