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 begins building large trenchers to lay underground pipelines in the 1980s. The first Vermeer horizontal directional drill is introduced in the 1990s. [9] The prototype of the first self-propelled hay baler is demonstrated in 2017. [10] [11]

Thus, a chain with half-inch pitch is a No. 40 while a No. 160 sprocket has teeth spaced 2 inches apart, etc. Metric pitches are expressed in sixteenths of an inch; thus a metric No. 8 chain (08B-1) is equivalent to an ANSI No. 40. Most roller chain is made from plain carbon or alloy steel, but stainless steel is used in food processing ...
