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. |
