BS 50-4 and BS 60-4 rammers feature a 4-stroke cycle engine—the WM 90, which is designed specifically for Wacker rammers. The 4-cycle rammer engine features a new air-filtration system, along with speed-stabilizing throttle linkage, 3-piece oil rings and a newly designed breather. The fuel system will not leak when the rammers are placed on their side, according to the company.
