Choosing between a 20 Ton vs 12 Ton log splitter depends on your fuel preference and splitting volume. Both units offer horizontal splitting for firewood preparation. The primary difference lies in their power source and force. One uses a gas engine for high-speed, automated cycles, while the other relies on manual hydraulic leverage. This choice dictates how much wood you can process and how much physical effort is required. You need to match the tool to your specific yard size and log dimensions.

Which one should you choose?
Choose AidBuilt 20-Ton 7 HP Gas Log Splitter if
- You need to process large volumes of wood quickly for sale or winter prep.
- You want to split logs up to 21 inches long without manual pumping.

20 Ton vs 12 Ton Log Splitter
splitting force
The AidBuilt 20-Ton Gas Log Splitter delivers 20 tons of splitting force, designed for the toughest logs up to 21 inches long and 16.5 inches wide. This high force allows you to tackle dense hardwoods and large diameters with ease, making it suitable for farm cleanup or firewood sales. In contrast, the BIG RED 12-Ton Manual Horizontal Log Splitter provides 12 tons of force. It handles logs up to 17.7 inches long and 7.9 inches in diameter. While sufficient for standard firewood prep, the 20-ton model offers significantly more power for difficult jobs. The higher tonnage on the AidBuilt unit gives it a clear advantage for heavy-duty splitting tasks.
power source
Power source is a major differentiator between these two machines. The AidBuilt model is gas-powered, featuring a 7HP 4-stroke engine and a dual-stage hydraulic pump. This allows it to operate off-grid without electricity, making it ideal for remote cabins or farms. It also includes a rapid auto-return hydraulic system for faster cycles. The BIG RED splitter is purely manual. It requires no gasoline, oil, or electric cords, relying instead on human leverage through 37-inch handles. This makes the BIG RED unit eco-friendly and eliminates exhaust emissions. If you prefer zero emissions and lower maintenance, the manual option is superior. For speed and independence from fuel, the gas engine wins.
cycle speed
Speed matters when you have a large pile of wood to process. The AidBuilt gas splitter features a rapid auto-return hydraulic system with an 8-second cycle time. This allows you to split up to 530 logs per hour, handling large-scale tasks efficiently. The hydraulic pump ensures consistent power delivery with each cycle. The BIG RED manual splitter does not list a specific cycle time. As a manual unit, the speed depends entirely on your physical strength and pumping rhythm. It uses a spring-loaded return knob to reset the ram quickly, but it cannot match the automated speed of the gas engine. For high-volume splitting, the AidBuilt model is significantly faster.
log capacity
Maximum log dimensions determine how much wood you can process in one piece. The AidBuilt 20-ton splitter accepts logs up to 21 inches in length and 16.5 inches in width. This generous capacity helps you process larger rounds without cutting them down first. The BIG RED manual splitter has a maximum log length of 17.7 inches and a diameter of 7.9 inches. While this is adequate for most residential firewood, it restricts the size of logs you can split. The AidBuilt unit accommodates larger timber, reducing the need for pre-cutting and increasing overall efficiency for bigger jobs.
portability
Both units are designed for portability, but they achieve it differently. The AidBuilt gas splitter is towable, equipped with 10-inch tires that make it easy to haul around farms or campgrounds. Its steel frame provides durability, though the gas engine adds weight and complexity. The BIG RED manual splitter weighs 77 pounds and includes wheels for easy movement over uneven ground, grass, or dirt. Its lighter weight and compact design make it easier to maneuver without a tow vehicle. If you need to move the splitter frequently without a truck, the lighter manual unit is more convenient. For long-distance hauling, the towable design of the gas splitter is better.
Which splitter fits your needs
High-volume firewood producers needing speed
The AidBuilt unit delivers 20 tons of force with a 7 HP gas engine. Its 8-second cycle time allows you to split up to 530 logs per hour. The dual-gear hydraulic pump and rapid auto-return system minimize downtime between splits. This high-speed performance makes it ideal for large-scale wood processing tasks where volume and efficiency are critical.
Budget-conscious users wanting zero emissions
The BIG RED manual splitter requires no gasoline or electricity, eliminating exhaust emissions and fuel costs. It offers 12 tons of splitting force for logs up to 17.7 inches long. The spring-loaded return knob resets the ram quickly. This eco-friendly design is perfect for occasional users who want a simple, maintenance-free tool without the noise or fumes of an engine.
Users needing portability and ease of use
This gas-powered splitter features a towable design with 10-inch tires, making it easy to haul across uneven terrain. The 7 HP engine provides reliable power for tough jobs without needing an electrical outlet. Its portable nature allows you to take it to remote cabins or campsites. The intuitive controls and rugged steel frame ensure durability while maintaining mobility for various job sites.

Frequently asked questions
Can a 12 ton manual splitter handle large hardwood logs?
No. The BIG RED 12-Ton Manual Horizontal Log Splitter is designed for smaller logs. It lacks the raw power of a 20-ton machine. You should choose a gas-powered unit if you need to process dense hardwoods or large diameters efficiently.
Is the 20 ton splitter portable?
It is less portable than manual options. The AidBuilt 20-Ton Gas Log Splitter measures 34.2 inches in length and weighs significantly more than manual models. Its gas engine and hydraulic system add weight. You will need a vehicle capable of hauling heavier loads.
Does the 12 ton model require fuel?
No. The BIG RED unit is a manual splitter. It does not use gas or electricity. This makes it an emission-free solution. You operate it by hand, which eliminates fuel costs but requires physical effort for each split.
What is the cutting capacity of the 20 ton gas splitter?
The AidBuilt model has a 5-inch cutting capacity. This refers to the maximum log diameter it can split in one pass. It is suitable for medium-sized rounds. You cannot split logs wider than 5 inches without repositioning them.
Which splitter is better for high volume firewood prep?
The 20-ton gas model is better. The AidBuilt unit features a 7 HP engine and auto-return function. This allows for faster cycle times and higher output. The manual 12-ton splitter is too slow for large volumes of wood.
How wide is the 12 ton manual splitter?
The BIG RED splitter is 7.05 inches wide. This compact width makes it easy to store in tight spaces. It is much narrower than the AidBuilt 20-ton model, which is 23.6 inches wide. Portability is a key advantage of the manual unit.
Can I split logs vertically with these models?
No. Both listed units are designed for horizontal splitting only. The BIG RED model is explicitly a horizontal splitter. The AidBuilt gas model also operates horizontally. You cannot switch these machines to a vertical orientation for different splitting styles.
