Lawn tractors electricity is 12 volts.
A decent pump will draw 8 amps from it. (my best Shurflo did)
Hence, the pump 'consumes' 96 watts of power.
Say the pump is 80% efficient (I'm being generous here) so the actual 'Pumping Power' is 77 watts.
The other 19 watts are lost to heating.
1 HP = 746 watts
77 watts = 0.103 HP (my electric motor)
5 HP = 3730 watts (my gas motor)
This is a 'simplified model'. Accuracy +/- 25%
