Jason and his guys did an inframe on my 2020 Pete with X15. It's been running for a month now no issues. Highly recommend if you have a x15tem

I called needing help with a hydraulic leak on a Motor-grader. Ryan came out and got us back up in running in no time. Thankful for all of Gray Bee's help. I was recommend to them by Mike the owner of Tiner Machine shop and they have not disappointed me with three repairs so far.
