Buying a Used CAT 302.5 Excavator

Where to Buy

There are several options for sourcing a used 302.5 excavator:

• Local equipment dealers - Most will have some used inventory or connections to get what you need.
• Online equipment listings - Sites like MachineryTrader let you search nationwide inventories.
• Auctions - A good way to get competitive pricing if you know the market.

What to Look For

When inspecting a used 302.5, some key things to check include:

• Component condition - Check pumps, motors, cylinders, pins, bushings.
• Maintenance records - Proof of regular service is ideal.
• Test operation - Cycle all functions and verify smooth operation.

Financing

Some equipment finance companies offer loans specifically for used gear. This allows you to purchase the machine then repay the loan over 12-48 months. Interest rates are typically reasonable as the equipment itself acts as collateral.

Warranties

Many used dealers offer 30-90 day warranties on their certified pre-owned equipment. Aftermarket warranty companies also offer policies that can provide coverage for 1-5 years.
