Power Train

The Cat® C9 engine with ACERT™ Technology delivers maximum power and combines with Electronic Clutch Pressure Control and planetary powershift transmission to offer superior performance and reliability in heavy-duty compaction applications.


Advanced design, materials and robotic welding contribute to increased durability and overall machine strength.

Operator Station and Controls

Operator comfort and productivity are maximized by an excellent viewing area, careful positioning of levers, switches and gauges, attention to air quality and sound control, as well as built-in convenience for the operator's personal items

Tamping Wheels and Tips

Tamping wheels, with a modified chevron pattern for the tips, offer greater traction, penetration and compaction for high production. The new cast bases make cleaning the wheels easier when moving the 815F Series 2 to a new work site.


Designed for general production dozing, road grading, spreading and clean-up work.

Optional Features

Air suspension seat, air conditioning, No-SPIN rear differential, fast fill adapter and cleaner bars are available to enhance the 815F Series 2. A rear view monitor and satellite radio options help make the operator more efficient and comfortable.


Many convenient service features such as hinged service doors, accessible scheduled maintenance points, conveniently located sight gauges, in-cab blade-type fuses and a separated cooling system make servicing easy.
