SERVICE
LAWNAIRE
DO NOT use tractor hydraulics to support the aerator while servicing. Hydraulic lines may rupture
causing unit to fall suddenly.
When replacement parts are required, use genuine Ryan parts or parts with equivalant
characteristics including type, strength and material. Failure to do so may result in product
malfunction and possible injury to the operator and/or bystanders.
LUBRICATION
1. Wipe off lubrication fittings before and after lubrication of aerating wheels. Lawnaire Model 544859 has
six lubrication fittings; Lawnaire Models 544860 and 544876 have eight lubrication fittings.
2. Lubricate aerating wheels after every four hours of use. Use a standard lithium based grease.
3. Lubricate aerating wheels daily (Model 544860)
4. Transport wheel bearings should be repacked yearly using a good grade wheel bearing lubricant.
Caution must be used when reinflating or bringing a low tire up to the recommended pressure.
Use a pressure gauge before connecting an air hose to a partially inflated tire.
Due to the low air volume requirements of a small tire, over-inflation may be reached in a matter of
two or three seconds, which may cause the tire to explode.
Tire Pressure (Model 544860)
Tires (Model 544860)

SERVICE
STORAGE INSTRUCTIONS
Thoroughly clean all tines, inside and out, after aerating is completed. A light coating of oil sprayed onto the
tines or blades will help prevent rust and ensure proper coring the next time the unit is put into service.
Unit should be stored on boards to protect tines or blades from rust and damage. Store in a dry location.
Lubrication before long storage periods will help prevent moisture build-up in the lubrication cavities.
When bringing unit out of storage, check for loose hardware and damaged parts. Tighten and replace as
needed.
FOR MODELS EQUIPPED WITH HYDRAULIC LIFT ACCESSORY
Check hydraulic cylinder for leaks and replace seal kit if needed. To obtain seal kit, order Part No. 884597.

ACCESSORIES
515196 - 1/2" Coring Tine
522361 - 3/4" Coring Tine, Thin Wall
515197 - 3/4" Coring Tine, Thick Wall
These tines are for use with aeration programs in
the Spring and Fall. Soil cores up to 4" (102mm)
in length can be removed with minimal surface
disturbance.
(Single Knife Part Numbers)
521155 - Deep Slicing Knife
515193 - Shallow Slicing Knife
Slicing knives are used for aeration and renovation
programs during all seasons. Slicing knives control
thatch by cutting through grass runners and also
have the advantage of no surface clean up after
aerating. Knives are especially helpful in that they
do not place buried seeds of noxious weeds on the
surface where they can germinate.
Slicing knives are especially recommended for athletic fields. Slicing allows moisture, air and fertilizer
to be absorbed while not creating hazardous playing
conditions for athletes.
520404 - Aerating Tine
These tines are for turf building and Fall renovation
programs. These tines will thoroughly open up the
soil by penetrating deep into the ground bringing up
large amounts of soil, which then becomes top dressing.
