John Deere FD22B, FS22B, FR22B, FR24B Felling Heads Operator Manual (F393279)

The John Deere FD22B, FS22B, FR22B, and FR24B felling heads are purpose-built harvesting attachments for professional forestry carriers. They are designed for felling, bunching, and handling timber in demanding cut-to-length and full-tree operations. This operator manual (F393279) provides day-to-day guidance on setup, control functions, and correct operating sequences for these models. It also outlines routine care, adjustment points, and troubleshooting practices needed to keep the head working reliably in the stand. Operators and service personnel can use it as a primary reference in the field or workshop.

### Applications & Use Cases

Mechanized felling and bunching of standing timber in production forestry.
Thinning operations where precise tree placement and control are required.
Clear-cutting tasks that demand consistent cutting cycles and high uptime.
Working on uneven or sloped ground where stable grapple and saw control are critical.
Integration with compatible John Deere carriers for coordinated boom and head functions.
Workshop setup, inspection, and adjustment after transport or component replacement.

### FAQ

Q: How often should I inspect the saw components on these felling heads?

A: Inspect the bar, chain, and related hardware at the start of each shift, and again after any impact or abnormal vibration is noticed.

Q: Can I switch between different tree sizes without changing factory settings?

A: You can handle a range of tree sizes, but if production conditions change significantly, verify clamp, accumulation, and cutting performance and adjust settings as needed.

### Safety Note

Always follow lockout/tagout and relieve hydraulic pressure before servicing or adjusting any part of the felling head.
