Connecting The Hydraulic Top Link - Toro ProCore SR54 Operator's Manual

To determine when to use the upper mounting
holes, refer to 10 Connecting the PTO Shaft
(page 14).
SR54 and SR54-S Aerators only
Note:
The hitch pins and lynch pins are shipped
installed on the SR54 and SR54-S aerators.

Connecting the
Hydraulic Top Link
Models SR54, SR70, and SR72
Parts needed for this procedure:
1 Hydraulic top link
1 Hydraulic hose (3-1/2 ft)
1 Hydraulic hose (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 tractor. If not, it will be necessary to
contact the tractor manufacturer to obtain the correct
couplings.
The tractor must be equipped with a double acting
spool valve with an operator control lever and two
12.7 mm (1/2 inch) quick-release couplings at the
rear of the tractor. The 2 quick couplings have been
provided to fit to the hydraulic top link hoses (1/2-14
NPTF hose end thread size).
This section will be used to install the hoses and
determine the need for the extension or rotation
blocks. This information will help to determine the
depth range of the aerator.
1. Secure the connecting link end of the hydraulic
top link to the tractor with the pins supplied with
the tractor (Figure
link so the rod end is toward the aerator. The
cylinder ports should be positioned toward the
tractor's auxiliary power hydraulics.
Note:
If the hydraulic cylinder must be
positioned with the ports facing upward, use the
rotational block instead of the standard mounting
block to reposition the cylinder
degree hydraulic fitting may be used instead of
the rotational block (fittings are not supplied).
Install the rotational block as follows:
A. Remove the cotter pin and pin securing
the standard connecting link to the cylinder
