5 ACRES AN HOUR? BULL ROAR!!!!

The newer Exmarks can mow pretty well running fast. One advantage is the blade tip speeds. Over 18000 fpm. Some of the older MMM's are closer to 16000 or less. Makes a huge difference.
I owned a Lazer Z for a while. It wasn't my favorite mower but it cut nice.

Hustler is supposed to have a zero turn mower that can mow at 16 mph.

That's really fast! At that speed you would need suspension. I remember the Dixie Chopper used to have a reputation for for top speed mowing.

I have a Kubota B2710 with a MMM and a Kubota ZD321 zero turn. Both about the same hp, the 2710 has a bit more.

The zero turn mows much faster on the straight aways and of course is more maneuverable around obstacles. The only place the zero turn loses out is on steep hillsides and rough ground where the tractor's bigger tires give a smoother ride.

Not having front brakes, the zero turn cannot be used at all going down steep hills forward. It has to be backed down. Of course, the tractor has to be in 4wd for braking.

I am having difficulty with this statement as I hydrostatic drive works as a brake as well so if it is working properly you should be able to mow up and down any slope that you do not lose traction on.

BTW - I mow about 2.5 acres and I regularly do it in an hour with my 60" front mount ZTR. This is real world including pond bank, around a dozen fruit trees, my house, my barn, my garden, along my driveway and various other trees and obstacles. You should be able to do this with any 60" ZTR although with my front mount I will have less trimming to do afterward.

For me it depends on seat, and the yard. I can run my dad's Hustler X-One at full speed, which is 11mph, all day. And, his yard is not by any means a golf course.

Like a dirt bike, or wave runner, going fast can actually smooth out the bumps, because you skip over them, rather than drop in them.

Flex forks are supposed to be helpful; I haven't tried them.

Most of the time, 11 mph is fast enough in my dad's yard. You need runs longer than 300' to be able to really utilize a mower that goes faster than 10 mph. He has some areas where it's over 500' which I would use more speed on, if his mower had it.

I think they do help.
I just added the flex forks this year.
I feel I can now mow at higher speeds more comfortably than last season before the flex forks.
They help take some of the sharp jarring out of the bumps

My Ferris can go up, down or sideways on a 20 degree slope and stop at any point using the HST transmission only. My box store Craftsman wont do that and will take off down the slope even sliding the tires or spinning them in reverse. It all has to do with weight and traction. My Ferris weighs 850# dry without operator while my Craftsman is light enough for two people to lift it on to a trailer easily. Much smaller tires, half the weight and less efficient hydraulic motors make it hard to handle on any slope which is but one of the reasons I bought the Ferris. The spring and shock suspension system of the Ferris makes for a super smooth ride, much smoother than either of my tractors.

I think you are making too big of a deal out of it. They aren't lying in any way. It most certainly can now UP TO 5 acres per hour. Like anything, it is just a spec for comparison. It factors speed and width. That's all. How else would you rate one that would keep every mfg on a level playing field??

Similar to how our tractors are rated to lift XXX pounds at the ball ends or pivot pins. Certainly not a real world number. But use full for comparison.

So if mower A advertizes 5/acres per hr, and mower B is 2.5/hr, while you may never attain those numbers, you know mower a will be twice as fast as mower b.

Respectfully disagree...it means the claim for mower B is more realistic. I used to have an Olds 98 with the digital dash and I could get a readout of "99 instantaneous miles per gallon" when I was coasting downhill. So, should GM have advertised "Up to 99 miles per gallon..." for that car? At one time my 3/4 ton Yukon XL pulled a loaded 9 ton ton box truck to start it when the battery failed....did that give me the right to claim my truck could pull 9 tons?

Heres the difference you don't seem to understand.
If you are cutting a flat smooth area with nothing to mow around the Exmark IS CAPABLE of mowing up to 5 acres Per hour.
