drum with guide pins always on the high side of the
convolution. Alternate between guide bars (A & B)
when aligning guide pins on the bars.

NOTE: When installing combination poly and steel

wafers, always start with wafer (#1) being a poly
wafer followed with wafer (#2) being a steel wafer.
Repeat that order until all wafers are installed.

! WARNING
To avoid serious injury or death:
• Do not alter attachment or replace parts on the attachment
with other brands. Other brands may not fit properly or
meet OEM specifications. They can weaken the integrity
and impair the safety, function, performance, and life of the
attachment. Replace parts only with genuine OEM parts.
1. Clean off any dirt and grease that may have
accumulated on the Hopper Broom and moving
parts. Scrape off compacted dirt and then wash
surface thoroughly with a garden hose.
2. Drain the spray system of water if storing the Hopper
Broom for the winter. Refer to “Winterize Hopper
Broom” on page 35.
3. Check dust skirt, broom, gutter broom, and cutting
edge for wear and replace as needed.
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 touch-up
paint. Paint is available in aerosol can, quarts, and
gallon sizes. See chart below.
