He isn't going near full sticks anywhere else in the video while close enough to get a good look at the cut. Maybe it's alright with you to do butcher work, but for those of us who depend on doing this for our income, we have more to think about than just bragging about having the fastest or strongest mower on some forum. We need to give the best we can or run the risk of losing an account to someone else in a time when LCO's are everywhere now.
Apparently you have no idea of what I believe, so don't put words into my mouth. You are arrogant in the extreme sometimes. The guy from Hustler sends me a reply with what they recommend, I post it, and now it's my fault that they happen to agree with me and not you?
If you want to mow your grass at full sticks, be my guest, but it doesn't make you right. Some guys have grass that they can geta way with it on, soome don't. You simply can't tell everyone here that it's ok with no caveat included about grass type or condition.
I can drive 120 mph on the ice too. It doesn't mean it's the best thing to do.
You've never heard me tell everyone they could go out and cut grass at 15 mph, but I have said you can cut grass in the right conditions that fast, and some have chimed in and said they did the same.
I think you can look back, and I feel assured anyone reading this that knows me has heard me say many times that I can cut grass at top speed because of being on relatively smooth terrain, and having stiff blade dryer type southern grasses to cut. I have always advocated that northern limp blade grasses are much more difficult to get a clean cut on, and you can find statements I've made that if cutting much above 3" the XR-7 Hustler deck would not give a clean cut in northern grasses at any speed.
I have also said that the Exmark Ultra Cut deck performed best in northern grass due to its more powerful suction, but you would be forced to scrape the deck more often than a deck such as the Scag Velocity Plus deck with its hybrid tunnel design.
Now, for you to say that it is impossible to cut grass at 15 mph due to your calculations showing a lack of blade tip speed may be correct as you saw it on paper, but you cannot disregard the fact that several besides myself in this thread, and many more throughout LawnSite have stated they do cut grass at those fast speeds.
So now, if you will concede that yes, it is possible to cut grass in the right conditions at 15 mph, and your calculations may not be exact in a real world cutting scenario, I will concede that I agree with you.
