The Ditch Witch organization introduces the SK850 footings machine, which is designed to create trenches up to 16 inches (41 cm) wide and up to 36 inches (91 cm) deep for slab construction on residential and commercial jobsites. With its specialized, heavy-duty chain and Tier 4, 37-hp (27.6-kW) diesel engine, the SK850 footings machine creates cleaner, more consistent trenches than an excavator can, and in less time. The machine is more compact than an excavator, so it can be more productive in tight jobsites. Plus, it can trench from either a centreline or offset position, so the operator can dig right up to the backer board. With 43 inches (109 cm) of track on ground, the SK850 footings machine also has the stability to effectively cross-trench.
