John Deere 45R Extra Horsepower Notes
Horsepower note
The John Deere 45R loses roughly 33.3% from engine horsepower to drawbar horsepower, which reflects drivetrain, traction and ground-contact losses.
PTO note
The John Deere 45R’s PTO output is 46.6 hp, about 103.5% of its 45 hp engine rating, so PTO implement choice should be based on the PTO number.
Drawbar note
The John Deere 45R’s 30 hp drawbar rating is the better number for ground-pulling work than the 45 hp engine rating.
Power-to-weight note
The John Deere 45R’s weight-to-power figure is about 71.1 lb per engine horsepower; that means it is light for its power, so traction and ballast can become the limiting factor before engine power.
Engine note
The John Deere 45R’s 1.7 L engine makes 45 hp, or about 26.5 hp per litre.
Torque / RPM note
The John Deere 45R’s 70 lb-ft torque rating works with its 2,800 rpm rated speed, so load response depends on both numbers.
Official information note
