Toro’s TRX-16 and TRX-20 walk-behind trenchers replace the TRX-15 and TRX-19 models. The gas-powered units come equipped with 4-cycle Kawasaki twin-cylinder engines with a large oil reservoir to help maintain low engine temperature and prolong engine life, delivering 10 gpm of hydraulic flow at 2,900 psi to the boom. The units can be outfitted with a 24-inch, 36-inch or 48-inch boom, and offer chain widths of 4 or 6 inches. The backfill blade mounts directly to the trencher and locks into place with a pin mechanism. www.toro.com/en-us/pages/default.aspx
