This is where we keep the tools that handle everyday farm and acreage work: rotary cutters for pasture and roadside mowing, flex-wing cutters for big ground, grooming mowers for a finished lawn cut, broadcast spreaders for seed and fertilizer, and manure spreaders.
Each model page lists the tractor horsepower, PTO speed and hitch it needs. Request a quote on any model and Koenig Equipment will help you match it to your tractor.

Match the implement to your tractor first: PTO horsepower, PTO speed and hitch category. Our team can confirm the fit before you buy.

What size rotary cutter do I need?
Start with your tractor. The RC6M cuts 72 in. and needs at least 30 PTO hp, the FC12E flex-wing needs 40-plus hp and the FC15E 50-plus hp. Larger R Series flex-wing cutters handle material up to 4 in. in diameter.
What warranty comes with the RC5M, RC6M and FC Series cutters?
The RC5M and RC6M rotary cutters and the FC Series flex-wing cutters carry a 12-month warranty with a 5-year limited gearbox warranty.
What is the difference between a rotary cutter and a grooming mower?
A rotary cutter handles tall grass, weeds and brush. A grooming mower like the GM40 gives a smooth, level cut on lawns, sports fields and golf courses, with caster wheels that follow the ground to prevent scalping.
Can I spread seed and fertilizer with the same spreader?
Yes. The SS30B spreads seed or fertilizer with three spread patterns, and its polyethylene hopper resists moisture and chemicals.
Do these implements work with iMatch?
Many do. The RC40 Series, GM40 Series and SS30B are iMatch compatible for faster hookup on tractors with an iMatch quick hitch.
