Continuously Variable Transmission (CVT) offers the best of both worlds
Continuously Variable Transmission (CVT) used in L-II skidders
Offering loggers the best of both worlds, the Continuously Variable Transmission (CVT) combines the efficiency of the direct-drive transmission with the smoothness and ease of a hydrostatic drive. Delivering efficient power to the ground, the CVT automatically senses the load before delivering more torque to maintain the operator's wanted speed. The CVT also eliminates the need to shift gears, which shortens the learning curve for new operators, and helps the experienced pros maximize productivity.
- Constant engine speed helps provide superb multifunction performance
- Easy to operate, especially for new operators
- Defined ground speed limiters allow you to control your operating speed
- No need to shift gears
Increase uptime with easy serviceability

Premium Cab for Premium Comfort
Operator sitting in premium cab in rearward seat position
The premium cab offers many comfort features for operators in their office all day. The automatic climate control allows operators to set their desired temperature and forget it. Climate control can be set through the primary display unit (PDU) or on the sealed switch module (SSM).
A secondary display unit (SDU) is also included in the premium cab option. The 7” (17 cm) SDU shows camera views, machine slope (fore and aft as well as side to side, in degrees), machine running temperatures, and light configuration. SDU is located on the corner B-post of the cab, this location is beneficial to operators when operating in the rearward seat position.
Cameras are a new feature included with the premium cab option. Blade view (located above the grill door) is a great opportunity for operators to use when pushing wood to the deck, road building, or traveling forward during thinning operations. Tong view (located in the boom) is beneficial to operators when grabbing a bunch or drag, maximizing grapple usage and operator efficiency. Cameras can be viewed on both the PDU and the secondary display unit (SDU). Each display can toggle between the blade view camera and the tong view camera to accommodate operator preferences.
A few other items included in the premium cab option are a RAM® mount cell phone holder, USB charging ports, windshield wiper, and CB radio mount ready.
