Introduction
Introduction
Land Pride welcomes you to the growing family of new
product owners.
Owner Assistance
The Warranty Registration card should be filled out by
the dealer at the time of purchase. This information is
necessary to provide you with quality customer service.
This implement 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 the machine.
If customer service or repair parts are required contact a
Land Pride dealer. A dealer has trained personnel, repair
parts and equipment needed to service the Rotary Tiller.
Application
The parts on your Rotary Tiller have been specially
designed and should only be replaced with genuine Land
Pride parts. Therefore, should your Rotary Tiller require
replacement parts go to your Land Pride Dealer.
The RTA20 & RTR20 Series Rotary Tillers are just right
for home gardening, landscape work, vegetable farming
or food plot maintenance. Available in three widths, the
20 Series Rotary Tiller turns up hard packed ground,
leaving a perfect seedbed for gardens to grass. Land
Pride’s RTA20 forward rotating tiller can work in all types
of ground conditions, with best results being obtained in
fairly mellow conditions. The RTR20 Series Rotary
Tillers feature a reverse tilling action for tougher ground
conditions. The reverse action “sucks” the tiller into the
ground, which prohibits the tiller from “walking” on hard
ground. The RTR20 Series Tiller also incorporates
spring loaded “sifting” rods behind the tines to help bury
large rocks and debris. The reverse action of the rotor
brings material up and over the top. Rocks and
Serial Number Plate
For prompt service always use the serial number and
model number when ordering parts from your Land Pride
dealer. Be sure to include your serial and model numbers
in correspondence also. Refer to Figure 1 for the location
of your serial number plate.
vegetation cannot get through the sifting rods so they fall
first. Soil continues to get sifted before it falls, building a
layer of large to small dirt clods burying the rocks and
vegetation. Reverse tilling can reduce the number of trips
needed to turn the soil over. See “Features and
Benefits”, “Section 6” for additional information.

fit between the tractor and tiller gearbox. Shorten
driveline as follows:
a. Set tractor in park, shut tractor engine off, set park
brake and remove switch key.
b. Pull driveline apart into two sections as shown in
Figure 1-6. Attach the outer driveline universal
joint to the tractor shaft and inner driveline
universal joint to the tiller gearbox shaft. Pull on
each driveline section to be sure the universal
joints are secured to the shafts.
c. Hold the 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.

Section 2: Operating
Operating Instructions
Before using your Land Pride RTA20 Series Rotary
Tiller, you should have completely read the Operator’s
Manual, properly attached the Tiller to the tractor, cut the
Drive-line 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.
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 extraneous debris. Best results will be achieved
if you have mounted your tiller offset to the left far enough
to cover the tread of your left 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 left to line up for your next pass. 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.
IMPORTANT: Turning or backing up with rotary
tines in the ground will damage the tiller.
Travel about 50ft. 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 of this Operator’s Manual.
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 in
this Operator’s Manual.
With a little practice and a few adjustments, you will soon
be achieving the results you want with your Land Pride
information and performance enhancing options.

SMecatioinn4:tMeainnteananncce aend Lubrication
Driveline Protection
Driveline components are protected from shock loads by
a friction slip clutch. The clutch must be capable of
slippage during operation to protect the gearbox,
driveline and other drive train parts.
!
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 can increase the life of
any 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.
determine which friction clutch your Rotary 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.

then re-engage a second time for 2-3 seconds.
Disengage PTO, shut off tractor and remove key. Wait
for all components to stop before dismounting from
tractor.
!
WARNING
Worn tines may be very sharp!
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 &
IMPORTANT: Always install tine with cutting edge
facing direction of rotor shaft rotation. When
ordering replacement tines, be sure to order both
right and left hand tines.
1. Remove 2 bolts and nuts from tine to be replaced.
Remove tine.
2. Install new tine on side of attaching flange.
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.
3. Replace 2 bolts and nuts and tighten nuts to proper
torque. See the Torque Values Chart in the
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.
IMPORTANT: Replace tines with genuine Land
Pride tines only.
