Cultivator was designed to cut a trench 7 feet 6 inches (2.29 m) wide and 5 feet (1.5 m) deep, and it would dispose of the spoil on banks either side of the cut trench. It could dig at 0.42 or 0.67 miles per hour (0.68 or 1.08 km/h) or travel at 3.04 miles per hour (4.89 km/h) on the surface. [24]
A sliding plate is attached to the front of the vehicle. This is used to prepare the site of the trench or, traditionally, for earthmoving and dozer and soil leveling tasks. All the mentioned works are performed in any climatic conditions in the temperature range from −40 ºС to + 40 ºС. Technical performance when digging trenches, m3/h ...
If the volume of work in the first part of the activity can be performed faster, the lag to the trench-digging can shrink, decreasing the drag in the predecessor and compressing the critical path. Occasionally, however, the lag on an SS relationship may be strictly a "time lag" representing a waiting period rather than work in the predecessor.
