Tell why these new garden tractor lawnmower needs a 24hp motor if they use an electric pto to turn the blades?

No im not why does there need to be a separate electric motor to run the deck?

I can't tell either, so I'm just going to jump in.

The blades are not driven by electric motors; they are belt driven like any other tractor. The "electric PTO" is just the clutch that engages the belt drive. In this case it is a button on the dash that you pull (usually) to engage and push to disengage, as opposed to a lever that you have to pull to activate the belt tensioner to engage the blades.

Yes that's what I meant by electric pto running the blades

My question is why did the engineers and designers feel the need to put such a big motor in a mower if the only thing the motor does is run the tires. They could have easily put in a 10 hp motor and saved on money since the electric pto motor runs the mower deck.

The engine still runs the deck. The electric part is simply a "solenoid" that activates the clutch (rather than a lever like alot of tractors) so belts are tensioned and thus the blades spin via the engine. It's not an "electric motor" that is spinning the blades like you seem to think.

Correct the big engine still runs the deck or if a snowblower is attached. The electric part is just what engages the deck(electric clutch) or snowblower. I used to have a 22hp and there were times I wished it was bigger. The motor runs both the tires and anything connected to the pto..which is turning via the motor. The electric part is just what engages the pto...you have mail lunk
