A log splitter is an effective way to increase productivity when chopping wood. The log splitter makes the job of cutting wood easier, faster, and more cost effective. This tool is useful for a variety of tasks: splitting wood to heat a home, cutting lumber to use in a given project, or even starting a lumber business. One consideration that must be calculated, however, is the appropriate splitter tonnage necessary for the task at hand. Calculating the splitter tonnage ensures that you use the right-sized equipment in relation to the logs you will be cutting. A log splitter simplifies the task at hand as well as makes other jobs possible.

Use the pressure gauge in the hydraulic line to reach from the cylinder to the end of the stroke. Keep the valve shifted at the end of the stroke to read the maximum pressure.

Measure the body of the cylinder tube and subtract 0.5 inches to come up with the total piston diameter.

Multiply the diameter you calculated by the gauge pressure in order to get the total pound force.

Divide the pounds of force by 2,000 to calculate the tonnage.
