1. Processing capacity: Horizontal balers have a higher processing capacity and are far less labor intensive than vertical balers. When processing more than two bales per day, the labor savings of a horizontal baler will quickly pay for itself. Horizontal balers will typically reduce labor costs by over 75 percent.

2. Versatility: Horizontal balers are more versatile than vertical balers as they can handle a wider range of materials, including large bulky items. They are also suitable for baling a wider range of materials.  While vertical balers are mostly limited to corrugated and stretch wrap, horizontal balers efficiently process paper, plastics, metals and other materials.

3. Efficiency: Horizontal balers are far more efficient than vertical balers, as the operator can continuously feed material into the machine, even during the ram cycle. A built-in shear eliminates the need to break down large items prior to baling. This allows for a faster and more efficient baling process.

4. Space-saving: While horizontal balers take up more floor space than vertical balers, they process material much faster. This eliminates the need for staging loose materials.

5. Safety: Horizontal balers are generally considered safer to operate than vertical balers, as more automated feeding methods reduce the need for constant bending and hand feeding by the operator.

Overall, the decision to choose a horizontal or vertical baler should be based on the specific needs and requirements of the user. These will primarily be the types and volumes of materials to be baled, available space and budget.
