The Ultimate Bulb Planting Tool

Powerful and efficient, our Large Bulb Auger is the ideal tool for planting bulbs and digging post holes with ease. Measuring 4 inches in diameter and 28 inches in length, it features a durable 1-inch shaft made of 100% steel. Choose between a Light-Medium Duty auger for home gardening or a Heavy Duty auger for professional landscaping.

For optimal performance, we recommend using this 4-inch auger with a large cordless drill featuring a 1/2-inch hex drive. This auger is designed to fit ½-inch drills, and our cordless electric drill bundle provides the necessary power along with a bonus battery and storage box—available exclusively from Power Planter! If using the heavy-duty variant with a Stihl BT45 Powerhead, be sure to purchase the threaded adapter for compatibility.
