As the name implies, it has a loader assembly on the front and a backhoe on the back. Backhoes attach to a three-point hitch on farm or industrial tractors.

When the backhoe is permanently attached, the machine usually has a seat that can swivel to the rear to face the hoe controls. Removable backhoe attachments
Backhoe marketed the Dynahoe as the only purpose-built backhoe-loader; previously all American backhoes were merely farm tractors fitted with front loader and rear backhoe attachments.

Production of the Dynahoe continued into the early 1990s culminating in the model Dynahoe 200-4, with a 36,000 lb. operating weight, 4-wheel drive, and a 20-foot dig depth. Production ceased with demand wavering in favor of more modern and versatile excavator type machines becoming more cost effective and productive. Many of the original Dynahoe Model As are still in use to
