If the hydraulic cylinder does not reach the aerator
mounting bracket, use an extension block instead of
the standard mounting block to connect the cylinder
to the tractor (Figure 5).
Note: If an extension block is installed and the
cylinder needs to be retracted to be installed, the
aerator tine heads will get closer to the ground.
Install the extension blocks as follows:
A. Remove the cotter pin and pin securing
the standard connecting link to the cylinder
(Figure 5). Remove the connecting link from the
cylinder.
B. Install the required length extension block to
the cylinder with the pins previously removed
(Figure 5).
