Garth,
Individual costs get a little murky when you are dealing on a larger package. But it seems to me it was about a $100 or $150.00 upgrade over the regular grill guard. I have no Idea what they run if you buy one outright.
On a mostly unrelated note, I have to say that I have been amazed at what a truly great lawn mower this thing is. With the 72" 7Iron dialed in right, the cut is superb. And the E hydro is just the best for maneuvering around obstacles or droning along with the cruise. I have found that if I am in cruise and I get to the end of a row and need to turn around, I just step on the reverse pedal. I cancels the cruise, coasts nicely to a stop, and then gently begins to back up. The whole operation is effortless and smoother than I could do with my old conventional hydro. Then head back down the row and hit resume.
