John Deere D100 Extra Horsepower Notes
| Horsepower note | The John Deere D100 has almost no visible gap between the listed engine horsepower and PTO horsepower ratings. |
|---|---|
| PTO note | With 19.5 hp at the PTO, the John Deere D100 is best matched to finish mowing, light-duty rotary cutting, light tilling and small utility PTO jobs; heavy hay tools, large augers and high-load PTO equipment are not the natural match for this power class. |
| Drawbar note | The John Deere D100’s 17.5 hp drawbar rating is the better number for ground-pulling work than the 19.5 hp engine rating. |
| Power-to-weight note | Using 442 lb operating weight and 19.5 hp engine power, the John Deere D100 comes out at roughly 22.7 lb per engine horsepower, meaning it is light for its power, so traction and ballast can become the limiting factor before engine power. |
| Engine note | The John Deere D100’s 30.6 cu in engine makes 19.5 hp, or about 0.6 hp per litre. |
| Torque / RPM note | The John Deere D100 lists 540 rpm as the rated engine RPM, which is the speed attached to its power rating. |
