Driveline Installation  
Implement End  
The tiller driveline is coupled to the tractor and implement  
shafts with either push pin couplers, pull collar couplers  
or a combination of both and with either a shear bolt or  
slip clutch on one end for protection from shock loads.  
Always engage the PTO at low engine rpm to minimize  
start-up torque on the driveline. Drivelines with friction  
clutches must go through a “run-in” operation prior  
to initial use and after long periods of inactivity. See  
a detailed description of maintaining the driveline.

IMPORTANT: Always check driveline maximum and  
minimum length during initial setup, when  
connecting to a different tractor and when  
alternating between using a quick hitch and a  
standard 3-point hitch. More than one driveline may  
be required to fit all applications.  
Implement End  
IMPORTANT: It is necessary to aligning the tractor’s  
PTO shaft level with tiller’s PTO shaft when checking  
to see if the driveline’s minimum length is correct.  
Too long a driveline can damage the tractor, gearbox  
and driveline.

insure that both ends are secured to the tractor and  
Rotary Tiller PTO shafts. Reattach any end that is  
loose.  
c. Hold driveline sections parallel to each other to  
determine if they are too long. The inner and outer  
shields on each section should end approximately  
1" short of reaching the universal joint shield on  
the adjacent section (see “B” dimension). If they  
are too long, measure 1" (“B” dimension) back  
from the universal joint shield and make a mark at  
this location on the inner and outer driveline  
shields.

extended driveline length. Check to make certain  
that the driveline overall length does not extend  
beyond the maximum recorded length in step 2.  
Shortening the driveline  
Figure 1-6  
Checking Driveline Maximum Length  
Make sure you have gone through the steps in  
before checking maximum length.  
Refer to Figure 1-7:  
The driveline maximum length must, when fully  
extended, have a minimum overlap of the profile tubes by  
not less than 1/3 the free length with both inner and outer  
profile tubes being of equal length.  
1. Apply multi-purpose grease to the inside of the outer  
shaft and reassemble the driveline.  
2. Assemble the two driveline profiles together with just  
1/3 overlapping of the profile tubes as shown in  
Figure 1-7. Measure and record this overall length for  
checking driveline length in step 9 below.

12. Tiller tines will cut better at a faster rotor speed than  
at reduced throttle.  
13. Do not engage PTO at full throttle.  
14. Tilling should not be done in wet conditions as soil  
will stick to tines.  
IMPORTANT: Always disengage the driveline  
before raising the tiller to transport position.  
15. After tilling the first 50 feet, stop and check to see that  
the tiller is adjusted properly.  
1. When raising the tiller to the transport position, be  
sure that the driveline does not contact tractor or  
tiller. Adjust the tractor’s 3-point hitch lift height so  
that the tiller tines are not lifted more than 14 inches  
off the ground to prevent damage to the driveline.  
16. Do not make turns or attempt to back up while tiller is  
in the ground. See important note below.  
IMPORTANT: Turning or backing up with rotary  
2. Be sure to reduce tractor ground speed when  
turning, and leave enough clearance so the tiller  
does not contact obstacles such as buildings, trees  
or fences.  
tines in the ground will damage the tiller.  
17. Do not engage PTO with machine in the fully raised  
or lowered position.  
18. Periodically check for foreign objects wrapped  
around the rotor shaft and remove them after  
disengaging PTO, turning off tractor, and removing  
ignition key.  
3. Select a safe ground travel speed when transporting  
from one area to another. When traveling on  
roadways, transport in such a way that faster moving  
vehicles may pass you safely.  
4. When traveling over rough or hilly terrain, shift tractor  
to a lower gear.

Section 2 Operating  
Lower the tiller half way to the ground and reduce your  
Parking  
tractor engine speed to about one quarter throttle.  
Engage the PTO and gradually increase the engine  
speed until you reach full PTO speed of 540 rpm. Lower  
the Tiller to the ground and simultaneously commence  
forward travel of approximately 2 mph. Do not make turns  
or attempt to back up while tiller is in the ground. See  
important note below.  
The following steps should be done when preparing to store  
the tiller or unhitch it from the tractor. See also Storage in the  
“Maintenance and Lubrication” section on page 20 for  
additional information on long term storage of your tiller.  
1. Park the tiller on a level, solid area.  
2. Shut off tractor engine and engage parking brake.  
3. Set parking stand to desired height to maintain tiller  
in proper height for re-hook-up and install pin to lock  
in place.  
IMPORTANT: Turning or backing up with rotary  
tines in the ground will damage the tiller.  
Travel about 50 ft. and then stop to check your results.  
When stopping, remember to lift the tiller out of the  
ground, stop the tractor, reduce engine speed,  
disengage the PTO, set the park brake, shut off the  
tractor, and remove the keys. If you are tilling too shallow  
or too deep, adjust the skid shoes accordingly. If the soil  
texture is too coarse, lower the leveling door and reduce  
your ground speed. If the soil texture is too fine, you will  
need to raise your leveling door and increase your  
ground speed. For any other problem conditions that  
may arise, you will want to refer to the Troubleshooting  
section on page 26.  
4. Unhitch from tractor.  
5. See Storage in the “Maintenance and Lubrication”  
section on page 20 if tiller is not going to be used for  
an extended period of time.  
Operating Instructions  
Before using your Land Pride RTA10 or RTA15 Series  
Rotary Tiller, you should have completely read the  
Operator’s Manual, properly attached the Tiller to the  
tractor, cut the driveline to proper length, Run-in the  
clutch, and gone through the Operating Checklist. If you  
have missed any of these steps, please complete them  
before proceeding.  
When you are done tilling for the day, make sure you use  
proper tractor shut down procedures before you get off of  
the tractor. If you are detaching your tiller, make sure you  
park it on a dry and level surface leaving it clean and  
ready for the next use. When you put your tiller up for the  
season, make sure you refer to the Storage Directions on  
Now that you have properly prepared yourself and your  
tiller, it’s time to do some tilling. Carefully drive the tractor  
to the site where you intend to till. You should have  
already cleaned this site of any large limbs, rocks,  
trash, metal or other debris. Best results will be  
achieved if you have mounted your tiller offset to the right  
far enough to cover the tread of your right tractor wheel.  
Line the tractor up just to the right of center on your tillage  
plot. You will be working from the center out and always  
turning to the right to line up for your next pass.  
With a little practice and a few adjustments, you will soon  
be achieving the results you want with your Land Pride  
Rotary Tiller. See “Features and Benefits” Section 6  
or “Specifications and Capacities” Section 5 for  
additional information and performance enhancing  
options.

Section 4 Maintenance and Lubrication  
Section 4 Maintenance and Lubrication  
Maintenance  
Driveline Protection  
Tiller drive components are protected from shock loads  
with a friction clutch or a shear bolt. The clutch must be  
capable of slippage during operation to protect the  
gearbox, driveline and other drive train parts. Shear bolt  
protection is discussed on page 19.  
!
CAUTION  
For safety reasons, each maintenance operation must be  
performed with the tractor’s PTO disengaged, the Tiller  
lowered completely to the ground or on safely supported  
blocking, tractor engine shut off and ignition key removed.  
Friction clutches should be “run-in” prior to initial  
operation and after long periods of inactivity to remove  
any oxidation that may have accumulated on the friction  
surfaces. Repeat “run-in” instructions at the beginning of  
each season and when moisture and/or condensation  
seizes the inner friction plates.  
Proper servicing and adjustment is the key to the long life  
of any farm implement. With careful and systematic  
inspection, you can avoid costly maintenance, time and  
repair.  
After using your tiller for several hours, check all bolts to  
be sure they are tight.  
Refer to Figure 4-2 below and Figure 4-3 on page 19 to  
determine which friction clutch your tiller has. Follow run-  
In, disassembly and assembly instructions for your  
specific clutch.  
Replace any worn, damaged or illegible safety labels by  
obtaining new labels form your Land Pride Dealer.  
Clutches With 4 Adjusting Nuts  
Clutch Run-In  
Tine Replacement  
Refer to Figure 4-1:  
Refer to Figure 4-2 (View - A):  
1. Using a pencil or other marker, scribe a line across the  
exposed edges of the clutch plates and friction disks.  
2. Tighten all 4 nuts uniformly until spring load is low  
enough that the clutch slips freely with PTO  
engaged.

facing direction of rotor shaft rotation. When  
ordering replacement tines, be sure to order both  
right and left hand tines.  
4. Inspect clutch and ensure that the scribed markings  
made on the clutch plates have changed position.  
Slippage has not occurred if any two marks on the  
friction disk and plate are still aligned. A clutch that  
has not slipped must be disassembled to separate  
the friction disk plates. See “Clutch Disassembly &  
6. Remove 2 cap screws and fasteners from tine to be  
replaced. Remove tine.  
7. Install new tine on side of attaching flange as shown.  
8. Replace 2 cap screws and fasteners and tighten nuts  
to proper torque. See The Torque Values Chart in the  
“Appendix” section on page 27.  
Refer to Figure 4-2 (View - B):  
IMPORTANT: Replace tines with genuine Land  
Pride tines only.  
5. Turn all 4 nuts fully back if no two marks on the  
friction disk and plate are still aligned. Clutch is ready  
for use.  
6. The clutch should be checked during first hour of  
cutting and periodically each week. An additional set  
of scribe marks can be added to check for slippage.
