John Deere 20C Extra Horsepower Notes

|---|---|
| PTO note | Use the John Deere 20C’s 18.5 hp PTO rating when sizing implements; the 18.5 hp engine rating is not the number the implement actually receives. |
| Drawbar note | For plows, ground tools and pull-type loads, the John Deere 20C’s 16.8 hp drawbar horsepower says more than engine horsepower alone. |
| Power-to-weight note | At 1,962 lb and 18.5 hp, the John Deere 20C works out to about 106.1 lb per engine horsepower, making it balanced enough that both traction and horsepower matter. |
| Engine note | With 0.9 L across 3 cylinders, the John Deere 20C averages about 0.3 L per cylinder. |
| Torque / RPM note | The John Deere 20C’s 36.7 lb-ft torque rating works with its 1,800 rpm rated speed, so load response depends on both numbers. |
