Maybe I wasn't clear enough. A disk not going very deep with the weight being carried on the tires would have less pounds/blade than a VT going as deep as possible. The concave shape of the disk creates more of a compaction layer versus straight blade if the pounds were equal. Where am I wrong with the physics?
Whatever tool you pull over the ground is compacting wherever it is touching by the weight of the tool. The shape has no bearing on the amount of compaction. The downward force of the tool is opposed by an upward force of the ground (equal and opposite). Your example of the disc supporting weight on it's wheels has less weight on the blades, but then the wheels are compacting. |
