The Prime Rock and Brush Grapple, built heavy with all grade 50 steel. It features a rock bucket that has two grapples, each with a 3,000 PSI cylinder, that work independently to grab objects using 3/8 grade 50 steel tines spaced 3 apart. The thickness of each tine, along with narrower spacing between them enables dirt to fall through while holding onto the larger fragments of material so you only pick up what you want. The 1/2 Grade 50 hardened steel cutting edge provides additional strength to the bucket making it incredibly durable even on the toughest jobs.
