| The tractive effort of the machine seems weak, especially in this deep snow that we have now. |
| The tractive force was, of course, the Eskimo dogs, and sledges were the means of transportation. |
| Operators of road slugs in the Northwest are usually lines with poor track and steep grades which require a lot of tractive effort, but not necessarily more horsepower. |
| 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. |
| The dynamometer car is constructed to indicate the tractive effort of the engine, the speed, and the distance travelled. |
