Gator and I have had a few problems over the past few weeks as well. Christine and Nina have been great about making things right, but I have lost a lot of fall winter prep time in the process.
Christine, if you read this (I'm guessing you will), please let us help you out with the couplers/quik-tach styles for the different machines. Between all of us on here you'll be able to get the info needed to build a database of tractor info and make orders right the first go-round. Alternatively, you could build an order sheet that the customer can fill out with blanks for hose length, coupler style, coupler size, and quik-tach style.
Just throw out a thread or PM us and we can help. I don't know a lot of these things off the top of my head, but KennyD, SPJenkins, et al do!! I'm always willing to go out to my machine with a tape measure or calipers.
