When was the first Dynahoe loader backhoe made?

How tall is the backhoe on the dynamic Dynahoe?
Maximum digging depth was 13 ft. and backhoe loading height 12 ft. Operating weight was just over 6 tons. Hy-Dynamic certainly set out to produce something superior to anything else available.
When did Hy Dynamic stop making the Dynahoe?
In 1966 Hy-Dynamic upgraded its Dynahoe models and launched a new range of machines with a 3-digit nomenclature, the first two digits indicating digging depth in feet. Models A and AD were replaced by the model 140, and other models in the new lineup included the short-lived 120 and 130 (discontinued by 1968), and the larger 160.

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.
Where is the control lever on a backhoe?
On most machines, the control lever for this attachment is located on the operator’s right while sitting facing forward. Pulling straight toward the rear raises the bucket, pushing straight forward lowers it, pulling it toward the center of the machine scoops, and pushing outward dumps it.
Why do you need to know how to operate a backhoe?
Check out the machine you’re going to operate. There are two obvious reasons for doing this: one is so you’re familiar with the machine, and the other is to make sure it is suitable for the job. Backhoes are available as track or wheeled machines with either 2 or 4 wheel capable configurations.
