The MK-4000 heavy-duty Concrete Saw has been engineered for operator convenience, improved accessibility for maintenance and better control during operations. The MK-4000 has been designed for both front and rear pivoting and has easily removable rear and side panels to provide easy accessibility for maintenance. One-year limited warranty.

The 57Hp Kubota WG1605-G-E3 is a 4 cylinder, 1537cc, in-line, gas fueled, naturally aspirated, liquid-cooled engine. It is fuel efficient, altitude compensating, has low emissions and meets EPA and CARB requirements. This engine offers very low vibration and is exceptionally quiet.

The 3-Speed Series offers the widest range of blade sizes, without pulley changes, of any saw available on the market.
