## Maximizing TMR Mixer Efficiency: Choosing the Right Bale Size and Characteristics
### Bale Size Considerations
When selecting a vertical TMR mixer, the size of the bales you feed plays a crucial role. For optimal performance, consider the following:
* **Capacity vs. Hay Density:** Mixer capacity dictates bale size, not physical dimensions. Capacity is determined by hay density, which varies with length (long vs. processed).
* **Full-Bale Feeding:** Choose bale sizes that allow you to feed full bales, for efficiency and uniformity.
* **Batching and Nutritional Needs:** Smaller bales enable you to mix different qualities or meet specific nutritional requirements.
### Bale Characteristics
Besides size, consider the following bale characteristics:
* **Weight:** Bale weight impacts mixer capacity. Dry hay packs at 3 lbs./cu. ft., while processed hay packs at 6-7 lbs./cu. ft.
* **Volume:** Bales with higher density take up less volume, allowing for more to be processed in a mixer.
* **Pre-Chopped Hay:** Pre-chopped bales may fit in smaller mixers due to higher density.
### Mixer Dimensions and Number of Augers
The physical space between the auger and mixer wall limits bale size. Twin auger machines offer increased space for dropping hay into the knives.
* **4×4 Bales:** 300-400 cu. ft. mixers
* **4×4 and 4×5 Bales:** 450-600 cu. ft. mixers
* **4×6 Bales:** 650 cu. ft. or larger twin auger mixers
### Optimal Bale Size for Different Operations
* **Small Cow-Calf Operations:** Consider producing smaller bales or using pre-cut hay to minimize mixer size.
* **Large Cow-Calf Operations:** Larger mixers (650 cu. ft. or greater) are required for 5×6 bales.
