Stump Grinder Maintenance Tasks by Usage Hours
Use this table as your go-to routine. It breaks everything down by hours of use-so whether you're grinding once a week or all day, every day, you'll know what to check and when.
| Usage Hours / Interval | Maintenance Tasks |
|---|---|

What This Table Shows
This checklist is sorted by how many hours your stump grinder has been used. It focuses on the main systems:
- Cutting system: teeth condition, cutter wheel wear
- Hydraulics: fluid levels, hose integrity, air bleeding
- Engine care: oil, air filter, spark plug, fuel filter
- Drive components: belts, chains, gearboxes, wheel hubs
- Safety: guards, warning decals, emergency stops
Each row represents a maintenance window-before each use, every 8, 25, 50, or 100 hours, plus seasonal tasks.
Why this matters:
Skipping just one oil change or ignoring worn belts can lead to serious damage. Worse, a missed hydraulic leak or bad tooth can cause safety hazards or shut you down mid-job. This chart helps prevent that.

🛠️ For Landscapers and Professionals
Running your grinder all day? This chart becomes your Bible.
- Log hours after every job to stay on schedule.
- Keep spare teeth, grease, air filters, and belts on hand.
- Set up reminders for 25-, 50-, and 100-hour checks-those are where problems show up.
❌ Mistakes to Avoid
- Dull teeth: They kill efficiency and overwork the engine. Sharpen or swap them out early.
- Skipping oil changes: Leads to overheating and internal damage.
- Neglecting hydraulics: Air in the system or contaminated fluid can damage the pump fast.
- Forgetting to clean: Debris builds up in tight spots and leads to corrosion or fire risk.
