John Deere Product Details
748L-III
Continuously Variable Transmission (CVT) Offers the Best of Both Worlds
The CVT combines the efficiency of a direct-drive with the smooth operation of a hydrostatic drive, delivering efficient power and eliminating the need for gear shifting. This helps operators maintain desired speeds and maximizes productivity by easing the learning curve.
Easy Serviceability Increases Uptime
The skidders are designed for efficient maintenance with ground-level access to daily service points, swing-out coolers for easy debris cleaning, and detachable engine panels for wide-open access. These features, along with remote diagnostics and extended hydraulic filter intervals, help reduce downtime and prevent costly repairs.
Primary Display Unit
Ergonomic, 12-in. Primary Display Unit centralizes machine gauges, work-time analytics, TimberMatic™ Maps/TimberManager™, camera views, and enables Remote Display Access for faster remote diagnostics and reduced downtime.
