Positioning Axle Mounting Brackets
The correct mounting position is determined by the formula outlined below -
Note: in some cases certain tractors have a low PTO and/or small wheels and therefore
have limited ground clearance, where this is the case, the operator must decide what is
sufficient ground clearance for his needs; where there is insufficient ground clearance the
latch arms can be pivoted down to a lower position. When doing this be aware that it will
cause the PTO shaft to become mis-aligned - Ensure you do not exceed the angular mis-
alignment allowed by the PTO shaft manufacturer and remember that this will reduce the
working life of the shaft.
With the frame in the vertical position, measure dimensions 'A' and 'B', subtract 'B' from 'A' to
obtain measurement 'X'. Measure dimension 'C'.
Select mounting holes which position the mounting bars in the end of the latch arms so that
dimension 'D' equals dimension 'C' minus measurement 'X' and also when the draft link is
horizontal and the rocking draft pin is in the upright position dimensions 'E' and 'F' are equal.
