Using Correct PTO Stub Shaft
The 1000 rpm stub shaft (A) has 21 splines for heavy PTO loads. The 540 rpm stub shaft (B) has 6 splines for implements requiring less than 56 kW (75 PTO Horsepower).
IMPORTANT:
Implements can be operated at 540 rpm only if the power input never exceeds 56 kW (75 hp). Operating PTO at lower speeds under heavy load could damage PTO.
