how much force is need to split a 20" x 20" green hedge log?

To determine the amount of force needed to split a green hedge log, you will need to consider a few factors: the species of the log, its moisture content, and the specific method or tool you plan to use for splitting.

Different wood species have varying properties, and some are easier to split than others. For example, softwoods such as pine are generally easier to split compared to hardwoods like oak. Additionally, the moisture content of the wood plays a significant role. Green wood, which has a higher moisture content, is more difficult to split compared to dry wood.

As for the specific method or tool used, it depends on whether you're using a mechanical log splitter, an axe, or another splitting tool. Each method or tool has different force requirements.

Assuming you are using a mechanical log splitter, these devices typically have a specified force rating. For instance, a typical residential log splitter may have a force rating around 20 to 30 tons. Keep in mind that this force rating refers to the maximum force the machine can exert.

If you are using an axe to split the log, the force required will vary depending on the sharpness and weight of the axe, as well as your technique and physical strength. It might be helpful to have some friends assist you if you are manually splitting the log.

In summary, the exact amount of force needed to split a 20" x 20" green hedge log depends on the wood species, moisture content, and the method or tool used. It is best to refer to the specific force rating of a mechanical log splitter or consider the tools and techniques used for manually splitting the log.
