A chain trencher cuts with a digging chain or belt that is driven around a rounded metal frame, or boom. It resembles a giant chainsaw. This type of trencher can cut ground that is too hard to cut with a bucket-type excavator, and can also cut narrow and deep trenches. The angle of the boom can be adjusted to control the depth of the cut.
Vermeer invents the first machine to dig, transport and replace large trees in the 1960s. The first larger round hay baler was invented by Gary Vermeer in 1971. Allis Chalmers first introduced the small round rotobaler in 1947. Vermeer begins building large trenchers to lay underground pipelines in the 1980s.
Example (inch, coarse): For size 7 ⁄ 16 (this is the diameter of the intended screw in fraction form)-14 (this is the number of threads per inch; 14 is considered coarse), 0.437 in × 0.85 = 0.371 in. Therefore, a size 7 ⁄ 16 screw (7 ⁄ 16 ≈ 0.437) with 14 threads per inch (coarse) needs a tap drill with a diameter of about 0.371 inches.
The discovery of a newly identified species — the oldest saber-toothed animal found and an ancient cousin to mammals — fills a longstanding gap in the fossil record.
