John Deere 1845F Extra Horsepower Notes
Horsepower note
The John Deere 1845F has almost no visible gap between the listed engine horsepower and PTO horsepower ratings.
PTO note
With 55.2 hp at the PTO, the John Deere 1845F is best matched to larger mowing, rotary cutting, tillage and medium utility implements; implement width and soil/load conditions still matter more than the horsepower number by itself.
Drawbar note
The John Deere 1845F’s 36.5 hp drawbar rating is the better number for ground-pulling work than the 55.2 hp engine rating.
Power-to-weight note
The John Deere 1845F’s weight-to-power figure is about 84.1 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
With 2.9 L across 3 cylinders, the John Deere 1845F averages about 1 L per cylinder.
Torque / RPM note
The John Deere 1845F’s 143.8 lb-ft torque rating works with its 2,300 rpm rated speed, so load response depends on both numbers.
Official information note
