Introduction  
Introduction  
Land Pride welcomes you to the growing family of new  
product owners.  
The parts on your Rotary Tiller have been specially  
designed by Land Pride and should only be replaced with  
genuine Land Pride parts. Contact a Land Pride dealer if  
customer service or repair parts are required. Your Land  
Pride dealer has trained personnel, repair parts, and  
equipment needed to service the implement.  
This Rotary Tiller has been designed with care and built  
by skilled workers using quality materials. Proper  
assembly, maintenance, and safe operating practices will  
help you get years of satisfactory use from this machine.  
Serial Number  
Model No. _____________Serial No. _______________  
Application  
The RTR12 and RTA12 Series Rotary Tillers are  
designed and built by Land Pride to till soil for seedbed  
and planting preparation with uses and applications in  
landscaping, gardens, and residential areas. They are  
adapted for 15-50 horsepower tractors with Category I  
three-point hitch mounting, 540 rpm PTO speed and are  
Quick-Hitch adaptable.  
For quick reference and prompt service, record model  
number and serial number in the spaces provided above  
and again on warranty page 33. Always provide model  
and serial number when ordering parts and in all  
correspondences with your Land Pride dealer. Refer to  
Figure 1 for location of your serial number plate.  
The reverse rotation tillers (RTR Series) tend to achieve  
greater depth penetration resulting in moving and  
pulverizing more soil. Also, they bury more of the residue  
in the soil.

!
DANGER  
A Crushing Hazard exists when hooking-up equipment to a  
tractor. Do not allow anyone to stand between tractor and  
implement while backing-up to implement. Do not operate  
hydraulic 3-point lift controls while someone is directly  
behind the tractor or near the implement.  
8. Continue with “Driveline Installation” on page 13.  
Driveline Installation  
The tiller driveline is coupled to the tractor shaft with  
a push-pin coupler and to the implement shaft with a  
bolted coupler. A slip clutch is provided on the implement  
end for protection from shock loads.  
!
WARNING  
Lifting unit more than 14" above ground with PTO engaged or  
engaging PTO with unit higher than 14" above ground can  
break the driveline and could cause flying projectiles.  
Always engage PTO at low engine rpm to minimize  
start-up torque. Drivelines with friction slip clutches  
must go through a “run-in” operation prior to initial  
use and after long periods of inactivity. See  
“Driveline Protection” on page 22 for detailed  
instructions on maintaining the slip clutch.  
!
CAUTION  
To avoid bodily injury caused by accidental falling of tiller,  
stabilize unit with parking stand and support blocks.  
If the Rotary Tiller is used on more than one tractor, an  
additional driveline may be required - especially if a quick  
hitch is used.  
Refer to Figure 1-7:

General Operating Instructions  
General Operating Notes  
Before using your Land Pride RTR12 or RTA12 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.  
Before beginning to till the following inspection should be  
performed:  
1. Check oil level in gearbox and chaincase. Refer to  
“Lubrication Points” on page 25.  
2. Check that all plugs have been replaced properly in  
the gearbox and chaincase.  
3. Be sure all tiller tines, bolts, and nuts are tight.  
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.  
4. Be certain all guards, shields, and dirt deflectors are  
in place and secure.  
5. Grease driveline shaft and all other grease fittings.  
Refer to “Lubrication Points” on page 25.  
6. Clear area to be tilled of rocks, branches, and other  
foreign objects.  
7. Tall grass and weeds should be mowed before tilling.  
8. Do not engage PTO at full throttle. Once engaged,  
increase throttle to 540 PTO speed. Tiller tines will  
cut better at 540 PTO speed than at reduced throttle.  
Lower the tiller half way to the ground and reduce your  
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.  
9. Tilling should not be done in wet conditions as soil  
will stick to tines.  
10. At first begin tilling at a slow forward speed and shift  
up as ground conditions warrant.  
11. Operated tiller with deck level to the ground.  
12. Tiller should be operated with the tiller deck level to  
the ground.  
IMPORTANT: Turning or backing up with rotary  
tines in the ground will damage the tiller.  
13. Tiller tines will cut better when operating the tractor  
at full 540 rpm PTO speed than at reduced throttle.  
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 rear deflector and reduce  
your ground speed. If the soil texture is too fine, you will  
need to raise your rear deflector and increase your  
ground speed. For any other problem conditions that may  
arise, you will want to refer to the Troubleshooting section  
on page 27.  
14. After tilling the first 50 feet, stop and check to see that  
the tiller is adjusted properly.  
15. 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  
tines in the ground will damage the tiller.  
16. Do not engage PTO with machine in the fully raised  
or lowered position.  
17. Periodically check for foreign objects wrapped  
around the rotor shaft and remove them after  
disengaging PTO, turning off tractor engine, and  
removing ignition key.  
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  
page 24.  
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  
Maintenance  
Proper servicing and adjustment is the key to the long life  
of any implement. With careful inspection and routine  
maintenance, you can avoid costly downtime and repair.  
The parts on your Rotary Tiller have been specially  
designed and should only be replaced with genuine Land  
Pride parts. Do not alter the tiller in a way which will  
adversely affect its performance.  
Check all bolts and pins after using the unit for several  
hours and on a regular basis thereafter to ensure they  
are tight and secured.  
Replace worn, damaged or illegible safety labels by  
obtaining new labels from your Land Pride Dealer.  
30355  
!
CAUTION  
For safety reasons, each maintenance operation must be  
performed with tractor PTO disengaged, tiller lowered  
completely to the ground or onto support blocks, tractor  
engine shut off, and ignition key removed.  
RTR12 Series Tine Replacement  
Figure 4-1  
Tine Replacement  
Refer to Figure 4-1 for RTR12 Series Tillers and  
Figure 4-2 for RTA12 Series Tillers:  
!
WARNING  
Worn tines may be very sharp.  
IMPORTANT: When ordering, be sure to order  
genuine Land Pride replacement tines only and to  
order both right- and left-hand tines. Always install  
tines with cutting edge facing direction of rotation.  
IMPORTANT: Remove and install one tine at a time  
to ensure they are oriented correctly when installed.  
30372  
RTA12 Series Tine Replacement  
Figure 4-2  
1. Remove the 2 hex head cap screws and fasteners  
from the tine being replaced and then remove tine.  
2. Attach new tine to the mounting flange making  
certain it is positioned so that the cutting edge  
crosses over the mounting flange and leads in  
rotation as shown in Figure 4-1 for the RTR12 Series  
or in Figure 4-2 for the RTA12 Series.  
Driveline Protection  
Tiller drive components are protected from shock loads  
with a two plate friction clutch.  
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.  
3. Replace removed cap screws and nuts. Tighten nuts  
to the proper torque.  
4. Repeat steps 1 to 3 until tines have been replaced.  
Clutch Run-In  
The clutch must be capable of slippage during operation  
to protect gearbox, driveline and other drive train parts.  
Friction clutches should be “run-in” prior to initial  
operation and after long periods of inactivity. To prevent  
driveline and gearbox damage, repeat clutch “run-in” at  
the beginning of each season and when moisture and/or  
condensation seizes the inner friction plates.

Section 4: Maintenance and Lubrication  
Refer to Figure 4-3:  
1. Using a pencil or other marker scribe a line across the  
exposed edges of the clutch plates and friction disks.  
2. Carefully loosen each of the 8 spring retainer nuts by  
exactly 2 revolutions. It will be necessary to hold the  
hex end of the retainer bolt in order to count the exact  
number of revolutions.  
3. Start tractor and engage driveline for 2-3 seconds to  
permit slippage of clutch plate and disk surfaces.  
Disengage driveline and re-engage a second time for  
2-3 seconds. Disengage driveline, shut off tractor  
and remove key. Wait for all components to stop  
before dismounting from tractor.

Clutch Disassembly  
Figure 4-4  
Inspection  
30560  
Inspect all parts for excessive wear and condition. Clean  
all parts that do not require replacement.The original  
friction disk thickness is 1/8" and should be replaced if  
the thickness falls below 3/32". If the clutch have been  
slipped to the point of “smoking”, the friction disks may be  
damaged and should be replaced. Heat build-up may  
also affect the yoke joints.  
Clutch Run-In  
Figure 4-3  
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 clutch plates from the friction disks. See “Clutch  
Disassembly” instructions below.  
Clutch Assembly  
Refer to Figure 4-4:  
Reassemble each friction disk (#4) next to the metal  
clutch plate it was separated from. Make certain all  
bushing are replaced in the same location as when  
removed. Install bolts (#3) through end plates and  
intermediate plates as shown. Place springs (#2) over  
each bolt and secure with nuts (#1).  
5. Tighten each of the 8 spring retainer nuts on the  
clutch housing exactly 2 revolutions to restore clutch  
to its original setting pressure.  
6. The clutch should be checked during the first hour of  
operation and periodically each week. An additional  
set of scribe marks can be added to check for  
slippage. See “Clutch Assembly” to adjust for  
proper spring length.  
Refer to Figure 4-5:  
Progressively tighten each spring retainer bolt until  
correct spring height (“A” dimension) is reached.  
Clutch Disassembly  
If the clutch run-in procedure, (See “Clutch Run-In” on  
page 22), indicated that one or more of the friction disks did  
not slip, the clutch must be disassembled to separate the  
friction discs.  
A = Measured length of each sprin  
before disassembling slip clutch.  
Use 1.15" for “A” dimension if  
measurements were not taken.  
Refer to Figure 4-4:  
IMPORTANT: Be Sure to measure and record  
length (A”) of each clutch spring before  
disassembling clutch.  
See IMPORTANT NOTE above before disassembling  
clutch. After measuring and recording each spring  
length, remove spring retainer nuts (#1), springs (#2) and  
bolts (#3). Each friction disc (#4) must then be separated  
from the metal surface adjacent to it.

Storage  
Ordering Replacement Parts  
Clean, inspect, service and make necessary repairs to  
the Rotary Tiller when parking it for long periods and  
when parking it at the end of a working season. This will  
help ensure that the tiller is ready for field use the next  
time you hook-up to it.  
Land Pride offers equipment in factory standard beige  
color with black highlights. Equipment in special colors  
may be purchased in Green, Red or Orange. Because of  
the variety of colors available, special attention must be  
given to the part number to prevent ordering the wrong  
replacement part. A suffix number corresponding to one  
of the colors below must be added at the end of Land  
Pride’s part number when ordering a replacement part  
with that color. Parts ordered without a suffix number will  
be supplied in factory standard colors.  
!
DANGER  
Always disconnect main driveline from tractor PTO and  
secure tiller in the up position with solid supports before  
servicing underside of tiller. PTO can be engaged if tractor is  
started resulting in damage to tiller, bodily injury, or death.

1. Clean off any dirt and grease that may have  
accumulated on the tiller and moving parts. Scrape  
off compacted dirt from bottom of tiller and then wash  
surface thoroughly with a garden hose. A coating of oil  
may also be applied to the areas where paint has  
been worn off from use to minimize oxidation.  
For example, if you are ordering a replacement part with  
part number 555-555C and the existing part is red, then  
add the suffix 83 to the end of the number to make the  
part number read 555-555C83.  
2. Check tines and tine bolts for wear. Replace if  
necessary. Refer to “Tine Replacement” on  
page 22.  
3. Inspect tiller for loose, damaged or worn parts and  
adjust or replace as needed.  
4. Repaint parts where paint is worn or scratched to  
prevent rust. Ask your Land Pride dealer for aerosol  
touch-up paint. They are also available in touch-up  
bottles with brush, quarts, and gallon sizes by adding  
TU, QT, or GL to the end of the aerosol part number.

on page 25.  
8. Drain and refill gearbox and chaincase oil. Be sure to  
replace all oil plugs when completed.  
• Drain oil in gearbox by removing bottom drain plug.  
See “Gearbox” lubrication instructions on page  
26.  
• Drain oil in chaincase by removing bottom level  
plug and tipping tiller towards the plug hole. See  
“Chaincase” lubrication instructions on page 26.  
9. Store tiller on a level surface in a clean, dry place.  
Inside storage will reduce maintenance and make for  
a longer tiller life.  
10. Follow all “Parking” instructions on page 18 when  
disconnecting tractor from tiller.
