Tackling a woodpile full of 20 inch logs is a different beast than splitting shorter chunks. The wedge has to drive deeper, the beam needs to stay rigid, and the hydraulic ram must deliver enough force without stalling. If you heat with wood, sell firewood, or clear storm damage, you need a machine that can handle that length reliably. Browse our log splitters collection to see the range available.

This guide focuses on the best log splitter for 20 inch logs, covering both electric and gas powered models. We will walk you through the key specifications that matter, including tonnage, cycle time, log capacity, and portability, so you can match a splitter to the way you actually work. Our picks are based on verified performance data and real user feedback from current owners.

Safety note: Log splitters generate enough force to cause crushing injuries, and splitting can send wood fragments flying. Read the operator’s manual before use and wear safety glasses or goggles, work gloves, and steel-toe boots, plus hearing protection with gas models. Keep hands clear of the wedge and ram, let only one person load and operate the machine, and keep children, pets, and bystanders well away from the work area.

How to Choose a Log Splitter for 20 Inch Logs

Tonnage and Splitting Force

Higher tonnage means more force at the wedge. For 20 inch logs, you want at least 6.5 tons for clean, dry hardwood, though many owners prefer 20 to 25 tons when facing knotty oak or elm. The Electric Log Splitter 16 Ton for Firewood is a strong electric option, while the 20-Ton Gas Powered Log Splitter gives you reserve power for larger rounds.

Cycle Time and Hydraulic Pump

Cycle time is how long the wedge takes to split a log and return to start. For 20 inch logs, a faster cycle means you can process more wood in an afternoon. The 20 Ton Gas Log Splitter-Full Boar Engine 209cc features an 8 second auto return and a two stage gear pump, which helps maintain speed under load. Electric splitters like the BILT HARD Log Splitter 6.5 Ton are slower but more consistent for small jobs.

Log Capacity and Beam Design

A 20 inch log splitter needs a beam and wedge that can handle the full length without bending. Look for a full beam design and a log capacity of at least 20 inches in length. The 20.5 in x 9.8 in Log Capacity from BILT HARD offers a 20.5 inch log capacity and a 9.8 inch diameter, which fits most residential needs. For larger operations, the BILT HARD 27-Ton Towable Gas Powered Log Splitter supports horizontal and vertical splitting to handle oversized rounds. As with any heavy equipment, the quality of the steel beam determines how long the unit lasts, much like the deck material on a mower, which we discuss in our fabricated vs stamped mower deck.

Portability and Power Source

Electric splitters are quiet, require no fuel, and are ideal for use near the house or in a garage. Gas splitters deliver more power and can go anywhere, but they need fuel and more maintenance. If you split at the woodpile, a towable gas unit like the SuperHandy Portable 25 Ton Gas Log Splitter offers maximum mobility. For occasional splitting close to an outlet, the BILT HARD 6.5 Ton Log Splitter, Wood Splitter is a lighter, more affordable option.

Once you settle on a machine, think about your whole property maintenance workflow. Many folks who split firewood also mow large acreage, and choosing the right deck size can save time.

Frequently Asked Questions

Can an electric log splitter handle 20 inch logs?

Yes, many electric splitters now handle logs up to 20 inches or more. The Electric Log Splitter 16 Ton for Firewood is a good example, offering 16 tons of force from a 17.4 amp motor. For dense, knotty wood, pay attention to tonnage and the condition of your logs.

How many tons do I need to split 20 inch logs?

For dry, straight-grained wood, 6.5 tons is usually enough. If you frequently split green or gnarled hardwood, a 20 ton unit like the 20 Ton Gas Log Splitter, 209CC 7HP Hydraulic will give you consistent results. In 2026, many buyers are choosing 25 ton splitters to handle tough ash and oak.

What is a good cycle time for a log splitter?

Cycle time is the time for the wedge to push through and return. For 20 inch logs, look for a cycle time under 15 seconds; the 20-Ton Gas Powered Log Splitter claims an 8 second auto return, which is excellent for high-volume work. Slower cycles are fine for occasional use.

Is a horizontal or vertical log splitter better for 20 inch logs?

Horizontal splitters are easier to use for standard 20 inch logs because you can place the log directly on the beam. Vertical splitters like the BILT HARD 27-Ton Towable Gas Powered Log Splitter are better for heavy, oversized rounds you cannot lift.
