Forgot to add, his [i:a5de4c82d2]source[/i:a5de4c82d2] said it wouldn't run anything over a 4 footer! :roll:First, I do about 12 acres, my 8N is certainly up to bush hogging it, even with the grass FAR higher than any "lawnmower" could handle, 3 feet or so.
Now that's a lotta bush hog for not much tractor!I saw it to-nite That 5ft'er takes on all comers... Some poor SOB is not gonna like what it tears up....
I'm thinkin' his buddy must have a John Deere for sale....His Source don't know his behind from a popgun.
I'd say you're right Bob. I think the 6 volt worried him even tho I told him about it starting easily in 18° weather last week.You are so lucky you "lost the sale" as the guy would have been after you FOREVER, for one thing or another, had he bought it.
orsepower is a measurement of what they call in the physics world 'Work'. Work is the application of a force over a time and distance. You want more horsepower you just have to increase your time and distance metric and keep the same force.(quoted from post at 18:10:17 11/23/14) Just lost a sale on an 8n because he didn't think it would run a bush hog good enough with HP in the mid 20's. (I've read 25-27?) He said his lawn mower is 18 hp & it won't cut it.
How do you explain the apples to oranges scenario here?

(quoted from post at 23:30:01 11/23/14) The 8n is rated @ 2000 rpm , if it were rated at 3600 rpm , with no muffler or air filter I would guess 45 hp would be close .
At 2000 rpm the 8n probably has 5 times the torque that a briggs has @ 3600 .

(quoted from post at 23:04:18 11/23/14) Now days HP is based on RPM where as when those old tractor where built HP was based on torque power so yep saying a lawn mower has more power it like comparing a big rock to a big tree. Neither one has to do with the other.
(quoted from post at 10:44:07 11/24/14) Them lawnmowers use small horses!
Lawnmower engine ratings are about as valid as anything a politician says.
Deceptive tactics, like lab test engines running special fuel, different carb settings, no accessories, and rpm tested for hp calc rich before engine detonates
(quoted from post at 11:10:49 11/24/14) An easy,uncomplicated answer is that with an N tractor,the horsepower is net HP. With a lawn tractor,mower,car,etc,it's gross HP. The net HP is what you actually have available to you for work,while the gross HP is only what the manufacturer says the Motor has. I saw tests on popular cars in the '70s,and some of the cars had motors which claimed 225Hp.but only delivered 45-50 at the rear wheel.My old '41 9n powers a 5' hog very well,and cuts grass and saplings that you have trouble walking through.
(quoted from post at 12:34:42 11/24/14) I have to disagree with you since if you compare a 24HP lawn more to the 8N the lawn mower does not come close as for TRUE HP
(quoted from post at 13:11:43 11/24/14) I understand the physics part of it but there is no way a 24 hp lawn mower engine produces more HP then the 8N engine does no way in the world it can do so.
(quoted from post at 10:16:45 11/24/14) Yes I do but there is no way you could have that 24 hp lawn mower engine if it could be done work as the engine of an 8N work

Here's how Gus Wilson answered the question: What Horsepower Really Is

ut....looking at your equation, you can trade torque for rpm or rpm for torque with simple gears.....still all the same hp, less of course a couple of percent gear loss.(quoted from post at 19:32:21 11/24/14) Horsepower for a rotating shaft, engine in this case is:
HP = {Torque(Lb-ft) X RPM} / 5252
Your 8N generates a lot of torque but at a relatively low RPM. That's why the HP numbers are fairly low. But when we're talking tractors, torque is what gets the job done.

(quoted from post at 20:15:40 11/24/14) 1 Horse power is the amount of energy it requires
to lift 100 pounds 1 foot in 1 minute.

(quoted from post at 22:47:13 11/24/14) Well I could not go to that site due to dial up but yes few understand HP and torque power and how RPMs can add HP but not add torque power and all in all not all things are as simple or add up when the work has to be done

Here's a video representation if you haven't seen it.
I find it quite funny! YouTube

easy to lie with statistics too.
