Larger Trenchers are used for construction and other jobs requiring big machinery. They might be created as freestanding pieces of heavy machinery or as tractors' attachments. In both situations, the trencher is driven over the ground being trenched by a heavy equipment operator who sits within the cabin of the machine and controls it from there, adjusting the depth and speed of the Trencher as necessary.
Wheel Trenchers and Chain Trenchers are examples of heavy equipment trenchers. Wheel trenchers are used in relatively mild soil, whereas chain trenchers, which function similarly to chainsaws, may cut into hard ground. Both can be risky to operate, thus extra care must be taken by the operator and anyone present at the worksite to prevent accidents. Also, the expense of this specialised trenching equipment might be high.
The word "Trencher" is also used in a food and eating sense, and is used to refer to a platter used to hold food. This is helpful for readers who have been reading novels set in the mediaeval era and have been perplexed by what heavy construction equipment was doing at the table. Wooden plates soon took the place of the original trenchers, which were chunks of half stale bread that were sliced into bowls and consumed after the meal. Usually, each diner was required to bring his or her own trencher and knife to the table for slicing and manipulating food. The word's two meanings are derived from the same root, which means "to cut."
