Grubbing is an excellent method to selectively thin mesquite infested land. Grubbing tears the roots loose with a push of a button. Our Bobcat uses 25,000 lbs of breakout force and hydraulically pulls the root ball out with ease. This is a great option saving the landowner valuable time and money using checmials to control this very evasive species. Typically we grapple these up and pile to burn.
