Digging holes for trees or posts by hand is exhausting. This gas-powered tree digger makes it way easier. It's got a 52cc two-stroke engine that puts out 1900W of power, with an impact force of 20-55 joules. It hits about 1500 times per minute, so it chews through soil pretty fast. The throttle is adjustable, and it has a manual pull-start. The fuel tank holds 0.3 gallons (about 1.1 liters), and it runs on a 25:1 gas/oil mix. There's a lock lever to secure the shovel attachment, and the handle is rubber-coated for comfort. It weighs about 43 pounds, so it's portable but still has some heft. Great for planting trees, shrubs, or setting fence posts in soil—NOT for rocky or concrete surfaces. Comes with the engine, shovel, funnel, tool kit, and mixing bottle. Wear ear and eye protection—it's loud.
