Description

Overview
The King Kutter 4-Foot Rotary Kutter (Model L-48-40) is a rugged, professional-grade implement engineered for small to medium-sized tractors (20–40 HP) tasked with reclaiming overgrown pastures and maintaining rough terrain. Constructed with a 12-gauge domed deck, this mower is specifically designed to shed water and debris, preventing the rust and material buildup that often plagues flat-top cutters. The defining feature is its Patented Flex Hitch system, which allows the unit to roll 15° in any direction. This unique flexibility enables the cutter to follow the natural contours of uneven ground, ensuring a consistent cut without “scalping” high spots or putting undue stress on the tractor’s 3-point hitch.

Durability and safety are at the core of King Kutter’s design. The machine is anchored by a 40 HP cast iron gearbox and features a heavy-duty stump jumper that protects the blade carrier from damage when encountering rocks or hidden stumps. The 1/2″ x 3″ heat-treated free-swinging blades provide a clean 48-inch swath, capable of slicing through brush and saplings up to 1 inch in diameter. Built with reinforced “I-beam” side rails and an adjustable laminated tail wheel, this rotary kutter is a long-lasting workhorse built for the rigors of farm and estate maintenance.

Top Performance Features

Patented Flex Hitch System: Allows a 15-degree range of motion (up, down, and side-to-side) to hug uneven field contours and reduce equipment strain.

40 HP Heavy-Duty Gearbox: A rugged, cast iron power transfer unit designed for high-torque applications and long-term commercial reliability.

Stump Jumper Technology: A circular, sloped blade-mount plate that allows the cutter to slide over solid obstacles rather than sustaining direct impact damage.

Heat-Treated Forged Blades: Two high-velocity, free-swinging blades designed to maintain their edge while handling heavy grass and light brush.

Domed Deck Design: Specifically shaped to prevent the accumulation of water and clippings, significantly extending the life of the 12-gauge steel frame.

Shielded PTO with Shear Pin: Provides critical drive-line protection by breaking a sacrificial pin if the blades strike an unyielding object.

Adjustable Laminated Tail Wheel: A puncture-proof, heavy-duty wheel that controls cutting height and provides stability during tight turns.

Quick-Hitch Compatible Cat. 1: Engineered for effortless mounting to Category 1 tractor hitches, making it easy to swap between implements.
