Adjusting The Tine Angle (Model Sr72); Adjusting The Tine Depth (Models Sr54-S And Sr70-S); Adjusting The Tine Depth (Models Sr54, Sr70, And Sr72) - Toro ProCore SR54 Operator's Manual

Adjusting the Tine Angle
(Model SR72)
Set the camber bracket
position based on the tine length. The head stop is
set to 1 of 5 predetermined positions by choosing
the hole through which you bolt the adjustment rod.
These holes are presets only; for instance, by using a
10-inch tine in the 12-inch position you may achieve a
smoother finish; depending on the application.
1. Disengage the PTO and engage the parking
brake.
2. Shut off the engine and remove the key.
3. Release the spring tension to the tine head
(Figure 38).
4. Remove the nut and bolt at the adjustment holes
in the camber bracket

5. Rotate the camber bracket until it aligns with
the desired hole in the arm, and install the bolt
and nut.
Note:
Make sure that the bolt goes through the
camber bracket and plate.
6. Connect the spring tension to the tine head.
Adjusting the Tine Depth
(Models SR54-S and
SR70-S)
You can change the tine depth by raising or lowering
the rear roller. You can adjust the roller height by
(Figure 38) to the correct
(Figure 38).

moving the roller adjusting bolts to the desired
position.
Note:
The factory ships the aerator in Position A.
•
Position A - Maximum depth
•
Position B - The depth decreases 38 mm (1-1/2
inches) from Position A
•
Position C - The depth decreases 76 mm (3
inches) from Position A
Adjusting the Tine Depth
(Models SR54, SR70, and
SR72)
Start the tractor engine and operate the tractor spool
g016132
valve to check the extend and retract motion of the
hydraulic top link.
Note:
Reverse the hose connections, at the tractor, if
they do not agree with the tractor control operation.
Run the aerator on a test plot to determine the desired
setting and note the corresponding position on the
depth indicator.
If needed, you can adjust the cylinder while operation
the aerator to a deeper setting (toward "J") or
shallower setting (toward "A").
Note:
The letters on the decal correspond to a
relative depth.
Note:
Extending the cylinder makes the aerator
penetrate deeper.
