Product Information
Used CAT 303 Mini Excavator for Sale
The used CAT 303 CR is a compact crawler excavator for construction, utility, landscaping, and property work. Its compact-radius design helps it operate in narrow areas. At the same time, its digging force supports trenching, grading, loading, and site preparation.
Longmai Machinery supplies used construction equipment to contractors, machinery dealers, rental firms, and project buyers. We provide current machine details, inspection support, test-run videos, export documents, and shipping plans. Therefore, buyers can review each available unit before placing an order.
Compact Design for Tight Work Areas
The CAT 303 CR is designed to work where space is limited. Its compact tail helps reduce the room needed for upper-body rotation. As a result, the machine can work near buildings, fences, roads, and other site limits.
The standard reference track width is 1,550 mm. Meanwhile, its standard shipping length is about 4,510 mm. These dimensions also make the machine easier to transport between small and medium job sites.
In addition, the front blade can grade soil, fill trenches, and clear loose material. It can also help support the excavator during digging. The pictured machine has an enclosed cab and steel tracks; however, the final configuration depends on the selected stock unit.
Cat Engine and Hydraulic Performance
The CAT 303 uses a Cat C1.1 Turbo diesel engine. It delivers 17.6 kW of net power at 2,400 rpm. Moreover, its compact engine design is well matched to utility, landscaping, and light construction work.
A load-sensing hydraulic system adjusts output according to the work demand. The variable-displacement piston pump provides a listed flow of 100 L/min. Therefore, the operator can get smooth control during digging, lifting, grading, and attachment use.
The machine provides 28.4 kN of bucket digging force. It also offers 16.6 kN of stick force with the standard stick. Consequently, it can handle soil, clay, gravel, and similar material on commercial job sites.
Travel, Blade, and Work-Tool Options
The excavator travels at up to 4.5 km/h in high speed and 2.6 km/h in low speed. Its listed gradeability is 30 degrees. Therefore, it can move between work areas and maintain useful traction on suitable ground.
The standard front blade is 1,550 mm wide and 350 mm high. It has a maximum digging depth of 535 mm. As a result, the blade can support backfilling, basic grading, and site cleanup.
Furthermore, compatible auxiliary hydraulic lines may support different work tools. Depending on the machine setup, available options can include:
- Digging and grading buckets
- Hydraulic breaker
- Auger
- Grapple
- Ripper
- Compaction attachment
- Quick coupler
Attachment compatibility and hydraulic requirements should be confirmed for the selected machine.
