TROUBLESHOOTING
Problem
Cause
Solution
Premature bearing failure.
Excessive strain on the hoe
wheel bearings.
Don't turn with rotary hoe wheels on
the ground.
Store the rotary hoe inside to help
protect the bearings from freezing
weather, moisture, blowing sand,
and dirt.
Keep all wheel bolts tight. Check
rotary hoe wheels for loose rivets
and bent teeth. Check for bent arm
castings.
Rotary hoe arm bending or
breaking.
Excessive strain on the arms
and wheels.
Don't turn with the rotary hoe wheels
on the ground.
Don't back the rotary hoe with
wheels on the ground.
Wings float up.
Air in system.
Check for air in hydraulic system
and purge system.
Gauge wheels not properly

Rotary hoe wheels plug
with trash materials.
Excessive trash conditions.
Decrease operating depth of hoe
wheels and increase ground speed
to create momentum so the hoe
wheels may clean themselves.
On softer, mellow soils, decrease
operating depth so that hoe wheels
do not pick up trash material.
Hoe
wheels
won't
penetrate.
Hard soil conditions.
Lower tool bar to maximize
