Ventrac 4500Z w/ Tough Cut - Mowing SWAMPY Drainage Ditch

Ventrac 4500Z mowing a drainage ditch with the Tough Cut (HQ680) in 6'+ tall, dense grass. The ground is VERY marshy and in places, quite muddy. On either side of the culverts (area in video is in the middle), the ground is EXTREMELY swampy and muddy, but the Ventrac still got the job DONE. I am confident in saying that the Ventrac 4500 with duals, is one of a very select few, if not the only, ride on machine that could operate, IN, the drainage ditch.
