The MTR12 and MTR16 microtrenching attachments are designed to cut a narrow (.75 to 2.25 in.) trench at maximum cutting depths of 12 and 16 in. Depth control is mechanically adjusted in 1-in. increments. A spring-loaded, flex pivot design and guide aid steering, and a lift and level design keeps the attachment flush with the surface to maximize cutter wheel engagement and vacuum performance in uneven conditions. The attachments are designed to work with the Vermeer RTX550 utility tractor. A range of cutter wheel configurations are available.
