| The dynamometer car is constructed to indicate the tractive effort of the engine, the speed, and the distance travelled. |
| We run and double back with the dynamometer car to try out our tractive power. |
| The tractive effort of the machine seems weak, especially in this deep snow that we have now. |
| And because the tractor unit is self-contained in a single unit, greater tractive effort can be applied to help move the unit through wet soils. |
| The final drives were selected for heavy-duty work cycles and a high tractive effort. |
| At a speed of 2.2 meters per second the tractive stress, K, is from 10 to 11 kilogrammes. |
