Product Description

Best Quality Rough Cut Mower AcrEase Model MR55B | 57″ Cutting Width| Pull Type / For ATV / UTV / Small Tractor

DESCRIPTION

The MR55B Rough Cut Mower is designed to handle tough grass, brush, and small saplings up to 2″ in diameter. Powered by a reliable 23 HP Briggs & Stratton Commercial Turf twin-cylinder engine, this mower delivers outstanding performance and is ideal for maintaining larger acreage properties.

With a 57″ cutting width and a unique twin blade design, the MR55B provides exceptional cutting efficiency and mulching action. Its manual clutch blade engagement offers straightforward operation, while the two-crank height adjustment system allows for easy customization of cutting heights between 2″ and 8″.

Built with a durable 10 GA steel deck, reinforced with multiple layers in the blade spindle area, this mower is designed to last in demanding conditions. The MR55B can be towed behind an ATV, UTV, or small tractor, either directly behind or offset to the side. With a 3.25-gallon fuel tank, the mower provides up to 3.5 hours of runtime for extended jobs.

Key Features

  • Powerful Engine: 23 HP Briggs & Stratton Commercial Turf twin-cylinder engine with cyclonic air filtration for improved durability and performance.
  • Manual Blade Engagement: Engage blades easily with a manual clutch lever for reliable operation.
  • Adjustable Cutting Height: Two-crank system allows height adjustments between 2″ and 8″ for flexibility.
  • Durable Deck Construction: Built from 10 GA steel with additional reinforcement for rugged mowing tasks.
  • High Blade Tip Speed: 19,000 ft/min ensures efficient and precise cutting.
  • Tow Versatility: Tow directly behind or offset to the side with a farm clevis hitch connection.
  • Large Fuel Tank: 3.25-gallon capacity provides 3 to 3.5 hours of runtime for uninterrupted operation.

23HP Briggs & Stratton Commercial Turf commercial grade twin cylinder engine

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 easily engaged by simply shifting a manual clutch lever.

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
