Common Visibility Issues in Forestry Equipment
Forestry machines like the Terex PT100 are exposed to abrasive dust, hydraulic mist, and branch strikes that degrade window clarity over time. Scratches, fluid stains, and UV haze accumulate on polycarbonate or acrylic door panels, reducing operator visibility and increasing eye strain. Unlike automotive glass, these windows are often made of impact-resistant plastics that require specialized care.
Operators frequently report that even after a full rebuild or service, the cab window remains cloudy or scratched, especially in high-usage forestry models. This affects safety during maneuvering and precision during boom or grapple operations.
Terminology Notes
Many operators have successfully used headlight restoration kits to restore forestry cab windows. These kits typically include:
Field Anecdote and Practical Insight
In Missouri, an operator restored his Terex PT100 forestry cab window using a headlight kit after noticing visibility loss from hydraulic mist and brush scratches. He reported that sanding and polishing improved clarity by 80%, though deeper gouges remained visible. He later added a removable Lexan shield to prevent future damage during mulching.
In British Columbia, a logging contractor used a commercial-grade plastic restoration system from a marine supplier to restore his Tigercat cab. The system included a rotary buffer and UV-resistant polish, which held up for over a year in harsh conditions.
Preventive Measures and Long-Term Solutions
Forestry cab windows are vulnerable to scratches and staining, but restoration is possible with consumer-grade kits and careful technique. Headlight restoration systems offer a cost-effective solution for improving visibility, especially on polycarbonate panels. For long-term clarity, protective shields and regular maintenance are essential. In rugged environments, visibility is not just comfort—it’s a safety imperative.

Terminology Notes
- Polycarbonate: A tough, impact-resistant plastic used in forestry cab windows; softer than glass and prone to scratching.
- Acrylic (PMMA): A clear plastic with better UV resistance than polycarbonate but more brittle.
- Headlight Restoration Kit: A consumer-grade polishing system designed to remove haze and scratches from automotive plastic lenses.
- Wet Sanding: A technique using water and fine-grit sandpaper to smooth surfaces without overheating or clogging.
Many operators have successfully used headlight restoration kits to restore forestry cab windows. These kits typically include:
- 800 to 3000 grit sandpaper
- Plastic-safe polishing compound
- UV sealant or protectant
- Buffing pad or drill-mounted applicator
- Clean the Surface Thoroughly: Remove all dirt, oil, and hydraulic residue with plastic-safe cleaner.
- Wet Sand in Stages: Start with 800 grit and progress to 3000 grit, keeping the surface wet to avoid heat damage.
- Polish with Compound: Use a microfiber cloth or buffing pad to apply plastic polish evenly.
- Apply UV Sealant: Protect the restored surface from future yellowing or haze.

Preventive Measures and Long-Term Solutions
- Install Removable Shields: Use bolt-on or magnetic Lexan panels to absorb impact and preserve the original window.
- Apply Anti-Fog and Anti-Scratch Films: These coatings reduce buildup and make cleaning easier.
- Avoid Abrasive Cleaners: Never use ammonia-based glass cleaners on plastic windows.
- Schedule Regular Cleaning: Monthly maintenance prevents buildup and reduces the need for aggressive restoration.
