I will take on that one
went and helped a friend mow he has a 24 hp Murray hst drive garden tractor 54" cut
my cc-yanmar has a 24 ho yanmar diesel 60" cut
he can mow at maybe 2 mph in tall grass level ground
I was maxing out low range hst in the same grass about 5.5 or 6 mph and occasionally slapping it in high range on the level areas mowing even faster
my cut was better than his I mowed 3 times the area per hour
there is a lot of difference between 24 hp gas and 24 hp diesel
and of course the whole build of the tractors is totally different
and as for pull he can hook a trailer with 1000lbs in it and not be able to pull it power wise
Mine will pull a 1/2 ton pickup out of a ditch ( just put a lot of weight in the loader bucket before you try that one
I disagree.
HP is HP. It doesn't matter what it is. Torque on the other hand is a different story. While a briggs may have high HP, they lack the torque down low. So no it wouldn't be able to move a 3000lb tractor very efficiently.
Torque is a measurement of how much work can be done.
HP is computed using the torque to derive how fast that work can be done.
While you make a valid point with the two mowers, if it's 24HP it 24HP. But when in tall grass, the smaller mower lacks the torque to keep the engine art max RPM, which is where the 24HP is. When it bogs down, it has way less than 24HP.
I'll give you an example of my own. I have a 29 PTO HP tractor with a 60" 3PH mower. My parents have a 23HP ZTR with a 61" deck. He can cut grass way faster than me, no matter how high, and leave a cleaner cut. And I'm not talking about the agility making him faster, in a straight line, he can mow at more MPH than me.
As far as pulling, again it has to do with torque, and gearing and not HP.
How's come a 310HP deisel motor in a 3500 will out pull a 345HP HEMI in the same truck?..........Torque.
