Bush Hog 720 Lawn Aerator User Manual


 
OPERATION
Level the implement from side to side and front to
rear using adjustments on the tractor’s 3-point lift.
Weight may be added to the plugger frame to aid in
penetrating hard soil. Concrete blocks, water jugs or
other types of weight may be used as long as noth-
ing extends through the frame and interferes with the
rotation of the spoons. Penetration should be
approximately one to 1-1/2”. (Figure 2)
By removing core plugs from the soil, lawns are bet-
ter able to breath and hold moisture. Compacted soil
and thatch are relieved, allowing air and fertilizer to
reach roots.
Optional slicing knives are available to replace
spoons on the mounting plates. Four knives per hub
are used to cut grass runners which causes new
growth and thicker lawns. Install as shown. (Figure 3)
Care should be exercised during use of the plugger
to prevent hanging the spoons on immovable objects
or otherwise use of the implement under conditions
beyond its designed capacity.
WHEN EQUIPMENT IS TRANSPORTED,
USE NECESSARY DEVICES REQUIRED
BY LOCAL REGULATIONS FOR ADE-
QUATE WARNING TO OPERATORS OF

LOWER THE IMPLEMENT AS MUCH AS
POSSIBLE AND SECURELY SUPPORT
BEFORE MAKING ANY ADJUSTMENT.
Inspect your implement periodically and replace any
worn or broken parts in order to have it ready for
use when needed.
When spoons become worn, replace one at a
time to ensure proper location and assembly.
Store the implement out of the weather when it is
not in use. This helps prevent rusting of the spoons
and other components.
