The Degelman RD320 is a trouble-free and versatile machine. Used for years by professional landscapers, contractors and farmers, the Degelman Prong Rock Picker and Digger are designed to clear big stones, boulders and for selective rock picking.

Hard Surfaced Digging Teeth

These hard surfaced digging teeth are two inches thick. This means the teeth won't bend, won't break, and will last a lifetime. The teeth are angled to allow for easy gliding into the soil while the hydraulics are in float position.

Serrated Grabbing Teeth

These serrated grabbing teeth allow for better gripping of the rocks.

Extra Long Teeth

Four extra long teeth allow the RD320 to dig down to 32 inches. The benefits of having four teeth are to provide extra grip, better control and handling, and less chance of the rock skidding or falling out. They also provide a more secure hold on the rock when transporting it.
