              27HP Kohler Confidant commercial grade twin cylinder engine with EFI (Fuel Injection)

              The blade spindles used on the AcrEase mowers are built out of heavy-duty welded steel hubs, 30mm (1-3/16") steel shafts, machined steel blade holders and large sealed ball bearings.

              The cutting height can quickly and easily be adjusted from 2"-8" with the two crank height adjustment system.

              The main deck is built out of 10 GA (.135") thick steel with a 1/4" thick steel top plate for reinforcement. An additional 1/4" thick steel plate is welded in the blade spindle mounting location. The three layers of steel in the blade spindle mounting area add up to just over 5/8" thick.

              Unique twin blade design provides more of a mulch action that reduces the size of the clippings and reduces bunching.

              The blades are engaged with an electric clutch which is activated by simply pulling a switch. Electric clutches can extend the life of the belt and reduce overall belt maintenance.

              The tow bar features a farm clevis type connection. This system provides more degrees of motion than most types of hitching systems. This is necessary to prevent binding in rough uneven terrain.

              Large 3-1/4 gallon fuel tank that provides 3 to 3-1/2 hours of run time



              Floatation Kit: 

              An extra front and back tire can be added to the center section of the mower deck.

              • Great for mowing around ponds and on rough uneven ground where scalping would normally occur.
              • Clamping style receiver allows for adjustments from side to side with both the front and rear tires.
              • Pinned receivers make for quick kit removal when not needed.
              • Works on all existing and new rough cut mowers.

              Wetlands Kit: 

              The Wetlands Kit consists of an extra set of tires and mounting brackets.

              • Great for wetlands or marshy areas that stay wet all year around.
              • Works well in combination with small personal amphibious vehicles and ATVs/UTVs with tracks.
              • Kit more than doubles the tire surface area in contact with the ground.
              • Easy to install.  Works on all existing and new rough cut mowers.
              • The rough cut mower will not float with the wetlands kit installed. Water greater than 2-3″ in depth should be avoided.
              • With the Wetlands Kit installed the minimum cutting height is 3.5″-4″.
              • Works on all existing and new rough cut mowers.

              Electric Lift Kit: 

              The Electric Lift Kit consists of all of the mounting hardware, brackets, electric actuator, and wiring with a remote control panel.

              • Great for constantly changing terrain and grass/brush heights.
              • Allows for quick cutting height changes on the go from the seat of the tow vehicle.
              • Raise up and over rocks and logs with ease.
              • Heavy duty 1500 lb linear screw actuator made by Linak.
              • Works on all existing and new rough cut mowers.
