I wanted to let you know about my experience with Otis Innovation, they make front axle vents for compact tractors. I have a Kioti CK 4020 and when I contacted them, they did not make one for Kioti. Instead of saying no we can’t help you, Jake went out of his way to work with me and make one for my tractor. After several emails Jake produced a vent. Unfortunately the thread pattern was not what we thought it was and although it fit, it wasn’t perfect. After I sent some pics and videos and we had a phone call he reproduced the vent with the dipstick and when I asked him what I owed him, he didn’t want me to pay any extra 
This is the kind of small American business I want to support. Jake and his family were absolutely awesome to deal with and make an outstanding product. The customer service is second to none.
