ROCK PICKER DURABILITY:
The rugged double wrap around the frame is all welded and constructed from heavy wall 5″ square tubing. The reel assembly features spring cushion action, individual hard surfaced teeth with heavy wall tube and carbon shafting and pins. The 1 1/4 cubic yard hopper on the 500-10 Rock Picker model and the 2 1/4 cubic yard hopper on the 500-20 model are constructed from 3/16″ and 1/4″ plate, square tube and angle on the grated bottom. The heavy duty pivot bucket hinges provide high strength and hopper stability. These features make the PFM rock picker the strongest and most durable on the market. It is built to stand up to the extra abuse demanded of rock removal equipment.
