MK-4000 Water Cooled Gas and Diesel Self-Propelled Concrete Saws


Torrance, CA, February 9, 2009 – MK Diamond Products, Inc introduced a new line of water-cooled gas and diesel concrete saws at this year™s World of Concrete. The new MK-4000HY and MK-4000KB are the latest addition to the MK Diamond line of self-propelled concrete saws. The low vibration water-cooled engines, meets all California and Federal emission standards.


The MK-4000HY features a 48Hp Hyundai 416, a 4 cylinder in-line, DOHC, gasoline fueled, spark-ignited, liquid-cooled engine. It is computer-controlled, fuel efficient, multi-port fuel injected, has low emissions and meets all EPA and CARB requirements. The engine utilizes a check engine light to provide diagnostic codes through a connector. This engine is 1599cc in displacement with a 10.1 to 1 compression ratio. It features a cast iron engine block and a cast aluminum head. This is a super quiet, powerful, low vibration, state of the art engine.


The MK-4000KB features a 44Hp Kubota V1505-T-E3B, a 4 cylinder in-line, diesel fueled, turbo-charged, liquid-cooled engine. It is fuel efficient, altitude compensating, has low emissions and meets all EPA and CARB requirements. The engine is 1498cc in displacement and features Kubota™s Three Vortec Combustion system, which produces an ideal air/fuel mixture that provides increased combustion efficiency and cleaner exhaust.


The operator™s controls feature a T-handle traverse control and a variable plunge speed control. Controls have been designed to allow easy, simultaneous one-handed operation of traverse, blade plunge and water flow functions. The throttle control is a power actuated system that holds the power setting exactly at the designated RPM. The 3-position handlebar adjustment provides operator convenience and comfort.


The blade guard is equipped with flexible water tubes that ride directly on the blade, which significantly decreases the amount of water mist. This decreases the amount of water necessary for cutting and produces less slurry while providing maximum blade cooling and lubrication. This water system also provides superior blade cooling at all depths. The right/left mounting of the blade guard is simple with the quick release spade mounts and water hose disconnect. Both saws are available with 18Âť, 24Âť, 30Âť and 36Âť blade guards providing a variety of cutting depths.


The MK-4000 series are the only large concrete saws on the market that are engineered for both front and rear pivoting.  This makes these saws extremely maneuverable for the operator on any jobsite. A unique feature of the MK-4000 series is the removable panels for maintenance accessibility. Other features include a maintenance free electro-hydraulic pump, 7 V-belt drive system that ensures maximum power transfer, and a totally enclosed, sealed blade shaft with continuous oil bath lubrication system.


The Eaton model 6 hydrostatic transmission is coupled to an MK engineered differential lock transmission. This differential lock transmission provides positive tracking during cutting on slippery surfaces and provides travel speed from 0-220 FPM in forward and 0-100 FPM in reverse. Another feature of the transmission is that it can be disengaged from the axle to allow the saw to be pushed manually.


MK Diamond Products, Inc. has been American-owned since 1868 and is a recognized world leader in the manufacturing of precision diamond blades and equipment for cutting, coring and polishing all types of masonry, concrete, tile and stone products. For more information call 800/421-5830 or visit
