Check for Correct Ballast

The best way to check for correct ballast is to measure amount of travel reduction (% slip) of the drive wheels. Under normal field conditions, travel reduction must be 10—15 %.

Add more weight for driving wheels if slip is excessive. If there is less than 10 % slip, weight must be removed.

Too Little Ballast		Too Much Ballast
1	Excessive wheel slip	1	Increased load
2	Power loss due to churning soil	2	Power loss due to carrying extra weight
3	Tire wear	3	Tire strain
4	Fuel waste	4	Soil compaction
5	Lower productivity	5	Fuel waste
		6	Lower productivity
