Product Description

GKB Drainmaster 105 | Working Width 59" | 120+ HP | For Tractors

DESCRIPTION

The GKB Drainmaster was designed to aid in surface drainage with no pipe installation all in one pass. Digging 2-3 trenches up to 10″ in depth while backfilling with sand all in one pass, making standing water a thing of the past.

The GKB Drainmaster has been in development since 1985, and we have kept refining the Drainmaster since then. The system has been developed in order to improve and accelerate the drainage of surface water. The result is your grass will continue to grow in quality and become more stable.
