Understanding the Timberline Delimber Platform
The Timberline delimber, particularly the 1995 model, was designed for high-volume processing of softwood and hardwood stems in logging operations. These machines were often mounted on trailers or tracked carriers and featured hydraulic knives, feed rollers, and a measuring system to optimize log length and bucking accuracy. The 1995 model incorporated the Timberline Smart System—a digital measuring device intended to improve productivity and reduce waste by tracking stem length in real time.
The Smart System Measuring Device
The Smart System was Timberline’s proprietary length measurement solution. It typically used a combination of a wheel encoder or feed roller sensor and a digital display unit mounted in the operator’s cab. As the stem passed through the feed rollers, the system calculated length based on roller revolutions or encoder pulses. The operator could then trigger a cut at the desired length using a preset or manual override.
However, many machines from this era were sold without manuals, and operators unfamiliar with the system often found it difficult to calibrate or activate. The interface was basic—usually a monochrome LCD with a few membrane buttons—and lacked intuitive prompts.
Common Issues and Troubleshooting Steps
If the measuring device is non-functional or unresponsive:
Tips for New Operators
For those unfamiliar with delimbers or digital measuring systems:
Timberline delimbers were widely used across North America in the 1980s and 1990s. Though the company no longer manufactures new machines, many units remain in service due to their rugged construction and modular design. The Smart System, while primitive by today’s standards, was a significant step toward automation in the logging industry.
Today, support for these machines is typically provided by independent mechanics, parts resellers, and former Timberline technicians. Some operators have retrofitted their delimbers with modern measuring systems from companies like Waratah or Log Max, but many prefer to keep the original setup for simplicity and cost reasons.
Conclusion
Getting a 1995 Timberline delimber’s Smart System measuring device operational requires patience, basic electrical troubleshooting, and possibly third-party support. While the system lacks modern user-friendliness, it remains functional and accurate when properly maintained. For operators willing to learn its quirks, the Smart System can still deliver reliable length control in demanding logging environments.

Common Issues and Troubleshooting Steps
If the measuring device is non-functional or unresponsive:
- Check power supply: Ensure the display unit is receiving 12V or 24V DC, depending on the machine’s electrical system. Corroded terminals or blown fuses are common culprits.
- Inspect sensor wiring: The encoder or roller sensor may have broken wires or loose connectors. Use a multimeter to test continuity.
- Reset the system: Some units have a hidden reset button or require a specific power cycle sequence to reboot.
- Calibrate roller circumference: If the system is reading but displaying incorrect lengths, recalibration may be needed. This involves inputting the roller diameter or encoder pulse count per revolution.
Tips for New Operators
For those unfamiliar with delimbers or digital measuring systems:
- Practice with manual measurement first to understand stem flow and cut timing
- Use a tape measure to verify system accuracy during calibration
- Keep a laminated quick-reference guide in the cab with button functions and error codes
- Clean sensors and rollers daily to prevent debris interference
