With this auger installed on a large electric drill, you’ll have the power to plant large bulbs and bedding plants with exceptional ease. The professional grade long handled bulb planter features double 10-gauge flighting – doubling the auger’s efficiency. Whether you’re a professional landscaper or a weekend gardener with a lot of space to cover, this auger makes your work a lot easier.


The Perfect Bulb Planter Tool

Our Large Bulb Auger is a powerful and professional tool for planting large bulbs and digging post holes faster and more efficiently. The bulb hole digger auger measures 4 inches in diameter by 28 inches long. It includes a heavy duty, 1-inch shaft made of 100% steel and your choice between a standard 1/2-inch non-slip hex drive or an adaptable tube drive.

We recommend using a large electric drill with 1/2-inch hex drive or a professional auger powerhead with this large auger. An auger powerhead is required for use with the adaptable tube drive. Our DeWalt 460 60v drill kit provides the power you need PLUS a battery and box – available only from Power Planter!

Our Rugged Post Auger is Versatile

The tube drive with a heavy-duty tip (THD) is the most rugged and versatile option for this auger. Use the dropdown menu above to choose the “THD” option. The heavy duty digging tip is a replaceable auger tip that will help you tackle the most challenging digging tasks without damaging the main auger. The leading portion of the digging tip has replaceable auger blades. This allows for an easier and more cost-efficient way to keep your equipment performing in top condition.

About Tube Drives

The tube drive auger can fit various drills or powerheads with the help one of our Adapters (sold separately). Our adaptable tube drive augers feature 2 holes with pins for mounting and will fit auger powerheads with a 3/4-inch shaft. This is a smart option for professional landscaping businesses who need to switch between drills and powerheads throughout the day. See graphic below for more details.
