For sale is a CAT 315CL. This has been a great machine! I've owned it for 4 years, mainly doing conservation work installing tile terrace systems and field drainage tile. Always serviced and oil samples pulled every time. The thumb is very handy and is easy to put on and take off. Just pull two pins and it comes off for more efficient digging. In good condition, has normal wear for the hours. Selling because I've updated. Hours might vary since the machine is still in use.
