There are several highly-rated logging trucks, including the Western Star 4700, Kenworth's T660 and Western Star's 6900. With many customized features available, these trucks fit highway and vocational needs.
The Western Star 4700 has a Detroit DD13 engine, which boasts 470 horsepower and 1,650 pounds-feet of torque. The truck has a steel cab and a sloped and sculpted fiberglass hood. It uses threaded spring pins to prevent movement from side to side within the shackle, while the internally-mounted door hinges help protect drivers from the elements. The 4700 lays claim to the largest door openings in the industry, with double-sealed doors to minimize noise and maximize the efficiency of the HVAC systems.
The Kenworth T660 has a PACCAR MX-13 engine with 500 horse power and 1,850 pounds-feet of torque. It has near-zero emissions due to the selective catalytic reduction and exhaust gas recirculation. Its cab and sleeper have ultra-luxurious leather, faux wooden trim and a fully tilting steering wheel. Due to the lane departure warning system, a side-mounted camera sounds an alarm if a painted line breaks up the picture of the unbroken pavement.
With the Detroit Series 60 Tier III engine, Western Star's 6900 truck has 500 horse power and 1,550 pounds-feet of torque, or 425 horse power and 1,475 pounds-feet of torque. It has grade eight fasteners and can haul over 500,000 pounds. It is also able to move 80,000 pounds at a time as a dump truck.
