Drain Tech is pleased to announce the addition of a Mastenbroek 35/20 to its fleet of drainage machines. Unlike our other machines that use a chain and cutter system to excavate the trench, this unit uses a single leg ripper shank to open the ground and feed the pipe to the trench floor. The unit is fully laser and GPS controlled for both grade control and steering. Both 100 and 150 diameter pipes can be layed down to two meters.
