FR27 felling head
From small stems to big timber, softwood to hardwood, level or sloped ground, John Deere has a disk saw felling head that’s designed for your job. The new FR27 boasts our highest single-cut-capacity, with over 16 percent more accumulation area than the FR24B, making it an excellent choice for large timber. Delivering efficient, multi-stem high-accumulation performance with huge pocket and tall horns, the FS50 and FR50 felling heads are best suited for thinning and high-production plantation harvests. For more versatile applications, the FS22B and FR22B heads are robust enough to handle large trees, with the tree-handling performance to also efficiently accumulate mid-sized timber. If lightweight is a must, the FR21B is our lightest, high-rotation head that is optimized for small to mid-sized timber.
- Wide range of in-house felling head attachments
- Optimized for John Deere carriers
- Heads are factory-installed
- High-rotation heads provide easier placement of bunches

Operate in comfort
Inside the cab of a 953M
Floor-to-ceiling front window
Operating for long hours is common. As the day goes on, maintaining consistent productivity is important. One factor in keeping high, consistent productivity is a comfortable operating environment. The M-series boasts greatly increased window area for better visibility and more cab space over prior models. Low-effort electrohydraulic (EH) controls allow you to customize the button and lever layout to your preference and save your settings when switching between operators.
- Large and spacious operator station designed with operator input
- Ergonomic controls and increased cab volume over prior models
- Floor-to-ceiling front window, large side windows, skylight, and optional floor window (standard on leveling machines) significantly expands operator visibility
- Optional heated and ventilated seat

- Remote diagnostics and machine monitoring with JDLink™
Sure-footed stability
U7 undercarriage
The M-series undercarriage is purpose built to handle severe forestry applications while maintaining maneuverability, especially in thinning operations. The track frames are shaped to deflect debris while also providing strength and stability.
- Long, wide undercarriage provides solid balance to maximize stability
- Exceptional tractive effort for negotiating difficult or steep terrain, deep snow, and swamps
- Optional closed-loop hydrostatic drive on 800M/MH models for increased multifunctioning performance
- Various track pad widths and grouser types are offered to best suit the machine to its application
- Optional tri-track helps prevent premature wear due to track twisting
Maximize stability on steep slopes
859MH working on a hillside
John Deere’s leveling system with smooth-cushioned control keeps the center of gravity over the tracks for exceptional stability on steep slopes. The expansive leveling envelope tilts up to 26-degrees forward for excellent steep-slope operation. Combined with a long and wide undercarriage, the leveling system maximizes performance in challenging terrain.
- Additional operator comfort when maneuvering on slopes
- Common undercarriage between the 859M and 959M leveling machines
- Maximizes boom and swing performance when working on slopes
- Provides exceptional stability and continuous machine operation on extreme slopes
Slope indicator
An available option on all leveling M-series machines, the slope-monitoring system measures the actual ground-slope angle the machine is working on and displays it on the in-cab monitor, for more confident operation in tough steep-slope conditions and potentially greater overall efficiency.
