CVT Transmission: Combining Rugged Durability with Smooth Operation

Many loggers have been asking whether our new, easy-to-use Continuous Variable Transmission (CVT) in the L-Series Skidder is a mechanical or hydrostatic drive transmission. The answer? Both!

The CVT transmission is a mechanical transmission that is hydrostatically assisted. That means it combines all the power and durability you've come to expect from a mechanical transmission with the smooth, easy operability of a hydrostatic drive. The many benefits of the CVT include better fuel efficiency, longer transmission life, and enhanced operator comfort. Here's how it works:

  • The CVT transmission automatically adjusts the output torque, ensuring maximum power to the ground. No more shifting – or "shift shocks" due to surging rpm.
  • Simply set the maximum speed and let the transmission do the rest. Speed ranges can be configured so the operator doesn't need to hunt for the correct gear. Meanwhile, the operator maintains easy and infinite control over vehicle speed.
  • The CVT enables a constant engine speed, maximizing horsepower utilization and fuel efficiency with minimal heat generation. Reduced engine wear means the powertrain is three to four times more reliable.
  • CVT automatically senses the load, delivering more torque and tractive effort as needed to maintain the desired speed.
  • Engine speed remains at a constant 1,800 rpm, enabling consistent multifunction performance and lower fuel consumption.
