AP-SG2572 & AP-SG2584- Skid Steer Grader 303-458MK

Maintenance

Proper servicing and adjustments are key to the long life 
of any attachment. With careful inspection and routine 
maintenance, you can avoid costly downtime and repair.

Check all bolts after using the unit for several hours to be 
sure they are tight. Replace any worn, damaged, or 
illegible safety labels by obtaining new labels from your 
Kubota dealer.

WARNING

!

To avoid serious injury or death:  

Do not alter Kubota equipment or replace parts with other 

brands. Doing so can cause equipment to perform 
improperly and may lead to breakage that can cause bodily 
injury or death. Replace parts only with genuine Kubota 
parts.

Never work under the Skid Steer Grader without blocking it 

up properly first. The grader can fall causing bodily injury 
or death. Always use solid blocks, never concrete blocks. 

Frequently check all hardware to make certain it is tight. 

Operating attachment with loose pins, bolts, or nuts can 
cause attachment to not perform properly and may result in 
a serious breakdown that can cause bodily injury or death.

Backup alarm must be in good working order to warn 

others. Use a backup camera or rear-view mirror that is in 
good condition to help see undesirable situations behind the 
unit. Drive at a slower speed to compensate for blind spots.

Long-Term Storage

1.

Scrape off compacted dirt and then wash the grader 
thoroughly to remove any dirt and grease that may 
have accumulated on the grader. 

2.

Repaint parts where paint is worn or scratched to 
prevent rust. A coating of oil may be applied to the 
lower unpainted frame area and blades to minimize 
oxidation.

3.

Check grader blades and bolts for wear and replace 
if necessary.

4.

Inspect for loose, damaged or worn parts and adjust 
or replace as needed.

5.

Repaint parts where paint is worn or scratched to 
prevent rust. Ask your Kubota dealer for aerosol 
touch-up paint. Paint is also available in touch-up 
quarts and gallon sizes.

6.

Replace all damaged or missing decals.

7.

Store grader on a level surface in a clean, dry place. 
Inside storage will reduce maintenance and make for 
a longer grader life.
