Introduction
Proper servicing and adjustments are key to the long life 
of any implement. With careful inspection and routine 
maintenance, you can avoid costly downtime and repair. 
Check all bolts after using the unit for several hours to be 
sure they are tight. Replace any worn, damaged, or 
illegible safety labels by obtaining new labels from your 
Land Pride dealer. 
!
CAUTION
Tractor Maintenance 
One of the most important things you can do to prevent 
hydraulic system problems is ensure that your tractor's 
reservoir remains free of dirt and contamination. Use a 
clean cloth to wipe hose ends before attaching them to 
your tractor. Replace your tractor’s hydraulic filter 
element at the prescribed intervals. These simple 
maintenances will go a long way to prevent occurrence of 
control valve and hydraulic cylinder problems.
Tine Replacement
!
WARNING
Always secure Aerator in the up position with solid supports 
before servicing the underside. Never work under equipment 
supported by hydraulics. Hydraulics can drop equipment if 
controls are actuated or if hydraulic lines burst. Either 
situation can drop the Aerator instantly even when power to 
the hydraulics is shut off.
“Right-Hand” or “Left-Hand” as used in this manual is 
determined by facing the direction the machine will 
operate while in use.
Stamped on the tines (see Arrows in Figure 5-1) is 
Land Pride’s name, tine part number, and LH for left-hand 
or RH for right-hand tine designation. 
Loosen 8 nuts (#2) on one hub two or three turns. 
2.
Remove two bolts (#1) securing tine (#4) if working 
on the Left-Hand Gang or tine (#5) if working on the 
Right-Hand Gang.
IMPORTANT: Make sure right-hand tines are 
mounted on the right-hand gang and left-hand tines 
are mounted on the left-hand gang and that the knife 
edge leads as the tine rotates about the shaft.
IMPORTANT: Tines are bolted on in a Spiral pattern 
22.5 degrees from one blade to the blade on the next 
flange over. Arrow in Figure 5-2 shows tines shifting 
22.5 degrees from one hub assembly to the next.
3.
Examine removed hardware for wear. Replace worn 
hardware with new hardware if required.
4.
Examine stamped information on the removed tine. 
Replace worn tine with a new tine that has the same 
stamped information.
5.
Install new tine (#5 or #6) by sliding one hardened flat 
washer (#3) over each 1/2"-20 x 3" GRL9 cap screw 
(#1) and then inserting the two cap screws into the 
thicker 5/8" plate first. After the bolt has been fully 
inserted, slide a second hardened flat washer onto 
the two cap screws as shown.
6.
Apply Loctite 246 on the end 1/4" length of threads. 
Screw hex flange lock nuts (#2) onto the cap screws 
on 3 or 4 turns only. Do not tighten.
7.
Repeat steps 2 to 5 until all four tines on a single hub 
have been replaced.
8.
Tighten all 8 hex flange lock nuts (#2) on that hub to 
the correct torque. See “Additional Torque Values” 
on page 24 for correct torque value.
9.
Move on to the next hub and repeat steps 1 t8. 
10. Continue reworking one hub at a time until all worn 
tines have been replaced with new tines.

IMPORTANT: Bolt installation direction is critical. 
Always insert bolts into the thicker 5/8" plate first.
IMPORTANT: Loctite 246 should be applied to the 
cap screw threads before installing lock nuts.
