He answered this question in other posts regarding the KK products and where they are made.
"King Kutter products are MADE in the USA. Tiller rotor bars are made here. The flanges are made here and welded onto the rotor bar. The top of the deck of the rotary tiller is formed in our plant. The deck for the rotary kutter is cut and formed in our plant, as are the side rails. We manufacture the stump jumper in our plant. The box frame for our discs are cut, punched, and welded together in our plant. The three-point frame is bent, and punched, and put together in our plant in the USA. To me... that's MADE IN THE USA."
"99.9% of the King Kutter equipment is made in the US, in three different factories. Only a few items like spin spreaders, cement mixers, and drag harrows are actually outsourced from overseas (not china).
Like all of the other big implement manufacturing companies, we buy gearboxes from China. King Kutter has extremely good luck with these gearboxes and have an extremely low failure rate. Extremely low."
"I want to address a couple issues in this thread which I beleive have been mis-represented.
1 - Unless something has changed recently the Woods machine also has a chinese gearbox. Woods, Land Pride, Bush Hog, Rhino, and King Kutter, all use gearboxes made in China.
2 - King Kutter has a failure rate of about 1 in 10,000 on gearboxes. I'm speaking of actual manufacturers defects here. So to whomever stated that the gearbox has been the weak spot of the King Kutter Finish Mowers, I'm sorry if you had an issue with one."
