McMillen X3575 Auger Drive for Skid Steers
Overview
The McMillen X3575 is a high-torque auger drive unit for skid steers — designed for the most demanding drilling conditions, including hardpan, caliche, and shallow bedrock. McMillen's X-series uses two-speed planetary gearboxes for maximum torque output. For Canadian contractors drilling in challenging prairie soils or near-surface rock formations, the X3575 reduces the need to switch to a dedicated rock drilling setup. Available through Canadian McMillen dealers.

Is This Right For You?
✅ Buy if…
- You drill post holes, footings, or tree holes regularly enough that buying beats renting
- Your skid steer's hydraulic output is matched to the drive unit — verify GPM range before buying
⛔ Skip if…
- You only drill occasionally — renting an auger package for $250–$400/day often wins over ownership at $3,000–$8,000 investment
- Your machine's GPM is outside the drive unit's rated range — running outside spec damages the motor
🔍 Also consider…
- A rental package first to confirm the right drive unit spec for your soil and machine
- Auger bits in multiple diameters — the drive unit investment only makes sense if you have the right bits to go with it
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.
