Features

Starfire S-4XL advantages

Massive lift scissors

Double X-style lift scissors and four-corner hopper lift support stable dumping with wet, sticky, or unbalanced debris.

Exclusive 3-shaft elevator

The third shaft supports chain return, improves chain life, reduces maintenance time, and helps the elevator load bulky debris more effectively.

Water and dust control

A 330 gallon tank, 3.6 gpm diaphragm pump, and spray nozzles at the front bar, main broom, and gutter brooms help control dust while sweeping.

Simple service access

Protected wiring, case drains, hydraulic pressure gauges, and lockable canopies keep the machine easier to diagnose, maintain, and keep in service.

Operator visibility

The standard camera system includes a dashboard-mounted 7 inch color monitor with right gutter broom and rear backup cameras.

Non-CDL productivity

A mid-sized conventional chassis keeps the S-4XL maneuverable while preserving heavy-duty hopper and broom performance.
