John Deere Worksite Pro TR48B TrencherPremium
🟢 Standard Flow
View on brandt.ca →
Overview
The TR48B is John Deere's 48-inch depth chain trencher in the Worksite Pro B-Series line — the right choice when utility runs or drainage work requires depth beyond the reach of the 36-inch TR36B. Same heavy-duty axle and wheel motor design as the TR36B, with the same replaceable spoil auger and spring-loaded boom. For Canadian drainage contractors, irrigators, and utility crews working in farmland or site development, 48 inches covers most conduit, tile drain, and service line requirements. Optional chain styles available for different soil conditions. Available in Canada through Brandt.
Canada Availability
Available in Canada through Brandt / John Deere Worksite Pro — dealer locations in BC, AB, SK, MB, and ON.

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
Compatible with all skid steer brands and compact track loaders via universal SSQA quick attach. Mid-frame machines (S450–S650 class) are the most common fit.

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
