I'm down with pneumonia at the moment, however, as soon as I can get up and out, I'll run (walk) to the Garage Mahal and shoot a photo or two for you.
Actually, it is a very simple install. Main thing you want to do is place the port where it is inboard enough to sit over the top of the lifting portion of the blade and direct the double head of the port toward the blade and the outer curve of the deck. There are two holes required to be successful. I didn't drill them, however, I am a master machinist and I can say that anyone can do it regardless of your expertise in drill bits and drill motors.
Just make sure the mower deck is off the ground enough to be able to get under the deck enough to see clearly to get your measurement for layout. Then move back to the top of the deck to place the larger of the two holes for the body of the port to protrude thru the deck. The second hole is the smaller of the two, most likely a quarter inch hole do hold the port direction in place. The direction of the port, once again, is very important, otherwise you'll only be shooting water under the deck and not breaking the compacted grass loose from the deck assembly.
I will get the photos up soon.
Good luck,
Max
