The Screedemon WS500 has an operating weight of 29 lbs., a Honda GX35 engine, and a fuel tank capacity of 0.17 gal. This machine employs a simple, durable, low cost rubber isolator to drive the eccentric. It produces irregular vibration along the length of the screed bar and simply clamps to the specially designed bar. No holes to weaken the screed bar and no threads to complicate assembly/disassembly. The Screedemon goes together and comes apart in seconds. Stop in or see us at the NORTHEAST HARDSCAPE SHOW APRIL 6-7, #NEHE2017, BOOTH #825.
