Note:
The factory installs the hitch pins and
lynch pins onto the SR54 and SR54-S aerators
before shipping.

Connecting the Hydraulic
Top Link
Models SR54, SR70, and SR72
Parts needed for this procedure:
1 Hydraulic top link
1 Hydraulic hose—106 cm (3-1/2 ft)
1 Hydraulic hose—76 cm (2-1/2 ft)
2 Extension bracket
1 Rotational bracket
2 Hose quick couplings
Procedure
Note:
Make sure that the supplied couplings are
correct for the traction unit. If not, contact the traction
unit manufacturer to obtain the correct couplings.
Your traction unit must have a double acting
spool valve with an operator control lever and 2
quick-release couplings 12.7 mm (1/2 inch) at the
rear of the traction unit. The factory provides 2 quick
couplings to fit onto the hydraulic top link hoses
(1/2-14 NPTF hose end thread size).
Use the procedure that follows to install the hoses
and determine the need for the extension or rotation
blocks. This information also helps you to determine
the depth range of the aerator.
1. Secure the connecting link end of the hydraulic
top link to the traction unit with the pins supplied
with the traction unit
Position the hydraulic top link so that the rod
end is toward the aerator and the cylinder ports
align toward the auxiliary power hydraulics of
the traction unit.
Note:
If you must position the hydraulic cylinder
with the ports facing upward, use the rotational
block instead of the standard mounting block to
reposition the cylinder
a 90° hydraulic fitting instead of the rotational
block (90° fittings are not included).
Install the rotational block 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.
