Our X-treme Rock Grapple is great for sifting through the dirt to get out the rocks. With the tines set at 2 1/2" apart, you pick up most everything but the dirt. With the use of the grapples, you can pick up large rocks, logs, brush or just about anything else. We use twin 2" bore by 10" stroke cylinders rated at 3000 psi on all of our grapples. Available sizes: 72" buckets - $2,832. 84" buckets - $3,021.
