Is This Right For You?
✅ Buy if…
- You trench through soft to moderate soil for utilities, drainage, or irrigation lines at 36–60 inch depth
- Your soil is clay, loam, sandy loam, or river bottom — chain trenchers cut fast in these conditions
⛔ Skip if…
- Your soil is solid rock, dense caliche, or Shield granite — chain links and sprockets wear out fast in rock
- You trench in deeply frozen Prairie ground regularly — rock chain at 3–5× wear rate makes winter trenching expensive
🔍 Also consider…
- Rock wheel trencher if your ground is consistently rocky or hardpan
- Standard auger if you're drilling individual holes rather than continuous trench lines
🔧 Machine Compatibility
Designed for John Deere machines but mounts to any skid steer or CTL with a universal SSQA quick-attach plate.

Care & Maintenance
- Inspect chain teeth after every use — worn teeth slow penetration dramatically and increase drive motor load; a full day's work can dull a chain in abrasive soil
- Lubricate the drive chain and boom sprockets before each use and again after every 4 hours of continuous trenching
- Check the boom bar for cracking or deformation after work in rocky or abrasive conditions — boom cracks propagate quickly under the bending loads of trenching
- Clean soil from the drive motor cooling fins and chain case after summer use — compacted soil on the motor causes overheating on long cuts
- Store the chain with teeth protected from ground contact — resting a chain on carbide tips on concrete chips the teeth before you've even used it
