Mega Slope Master MSM-T4E

The Biggest and the Best Slope Mower

The MegaSlopeMaster is the big brother of the SuperSlopeMaster slope mower. It is used in the same environment as the SuperSlopeMaster, offering the heavy duty commercial user a larger machine. The big 72 HP turbo diesel engine will mow through the toughest growth on up to 40° slopes. This machine is truly a slope mowing giant.

World's Largest ZTR Land Clearing Slope Mower

The MegaSlopeMaster is the largest zero-turn-radius (ZTR) steep slope mower for sale manufactured in the world. With an 88” cutting width, nothing will cut your slopes faster or more efficiently.

It is a commercial slope mower designed for land clearing on smooth and rough terrain. Heavy grass and weeds, light brush, and small saplings are no match. It is powered by a water cooled 72 HP Yanmar turbo diesel engine, which turns three independent 3/8” thick cutting blades. Each blade has its own hydraulic drive motor, which eliminates the typical single drive belt.

Rough & Rugged

The MegaSlopeMaster is built using 1/4" steel members. It will withstand impacting an object at 6MPH without damage to the machine. The mowed materials are rear discharged for maximum safety from thrown objects.

Two Blade Styles

Blades are available in flat and high lift configurations to handle both rough cutting and finish mowing. Combine that cutting power with true zero-turn-radius maneuverability, and you have the most efficient slope hillside mowing machine in the world. Other skid steer zero-turn-radius machines cannot compete with the MegaSlopeMaster.


  • Ability to mow all day without refueling in even the most demanding conditions

  • Adjustable tilting seat with suspension keeps the operator upright and comfortable

  • Four Point Safety Harness

Landfill mowing, closed landfill slope, best slope mower, landfill slope mowing, steep slope, riding mower
  • Rear discharge for reduced thrown object risk

  • Tip-Up Stop prevents the machine from rolling over backward

  • ROPS produces “cone of protection” in the event a machine does roll over sideways


Years of experience with the SuperSlopeMaster confirmed that for maximum efficiency, the steep slope mower needed to be a true zero-turn-radius style machine. Close trimming is now possible without a second machine!

The heavy duty deck can handle all grass and brush mowing without leaving the slope. The MegaSlopeMaster's power allows it to cut the tallest grasses without slowing. Its special anti-wrapping devices automatically removes spindle wraps.


Safety was an equally important design criteria. As with all Kut Kwick machines, the operator is seated at the rear of the machine close to the ground as far away as possible from the moving parts of the engine and deck. Should the operator need to get off the machine in case of an emergency, the first step is onto solid ground, and that step will be at the far extremity of the machine away from the cutter deck.

Safety Lanyard

The machine is fitted with a safety lanyard that not only stops the engine and deck, but locks the machine down, automatically stopping the machine if the operator leaves the seat.

Out-Front Cutting Deck

The design with an out-front deck is also a great safety feature. It assures that the operator will avoid one of the most frequent tractor drawn rotary mower accidents that occurs because the tractor operator has to continuously look back over his shoulder to observe the cutter operation. The MegaSlopeMaster operator knows what the problems ahead may be because he/she is always looking forward.

Ergonomics & More

All the controls of the MegaSlopeMaster are ergonomically located for safety and convenience. The tilting seat keeps the operator up-right even when cutting on slopes. The tilting seat mechanism allows the operator to safely and smoothly turn the machine 180°, reversing the direction of travel on the slope without stopping.

Komfort Kontrols

The Komfort Kontrols joystick style controls are attached to the arms of the seat and move with the seat. The joysticks are operated independently to steer the machine and to control its speed. The machine can be made to reverse its direction by directing one joystick forward causing the wheel on that side to roll forward while the opposite joystick is directed back causing its wheel to roll in reverse making the machine change direction within a zero-turn-radius (ZTR). Additional security is provided by the 4-point harness that is built into the seat.
