I ran a 3 mile dredge project down a bayou, to produce a 40’ wide 5’ deep channel through an old cypress swanp with 20 ft diameter stumps. The mats we used, 3, were 20’ long and 20’ wide made of 12” thich x 12” wide beams cabled together using 1 1/2” steel cable, with 3’ loops sticking out pf both sides. The Trackhoe sitting on the mats, came in three parts, on low boys, had a 3 yard bucket, a big motor scooter. The mats themselves came from LA.
The operator started on an earthen dam, dug 40’ wide and 20’ long in front of him, spun around grabbed a loop and picked up a mat, dropped it in front of him, pulled out onto it and away he went down the bayou. Until he slipped off the mat… it took two of those big tractor trailer wreckers, side by side, using huge pine trees as anchors to pull him out.
It ran up to the top of its tracks in the water on the mats.
The tractor, round tires, a lot of weight on a small square inch surface, is not a good choice for muck work.
I grew up in the Glades, muck, everyone uses crawlers because of the soft land surface.
