Backhoe loader of the backhoe could cause the vehicle to tip, most backhoe loaders use hydraulic outriggers or stabilizers at the rear when digging and lower the loader bucket for additional stability. This means that the bucket must be raised and the outriggers retracted when the vehicle needs to change positions, reducing efficiency. For this reason many companies offer miniature tracked excavators, which sacrifice the loader function and ability to be driven from site to site, for increased digging efficiency. Their relatively small frame and precise control make backhoe-loaders very useful and common in urban engineering projects such as construction and repairs
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. The Dynahoe was built very robustly from the ground up with heavy excavation in mind. 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
