Upon receiving the unit, you will find the main crawler-mounted drilling rig, which arrives partially assembled to facilitate shipping. The package includes the main drilling attachment, a set of basic drill rods, a hydraulic control panel, and the necessary hoses and connectors. Documentation includes an operation manual, a parts list, and a warranty card. The packaging is industrial-grade, with sturdy wooden crating and ample foam padding to protect the steel components during transit. First impressions of the build quality are positive; the steel frame feels robust, and the hydraulic components are well-sealed. However, note that this compact borehole drilling equipment does not come with a full set of drill bits or a mud pump, which may be required purchases depending on your specific drilling application. For a complete setup, consider ordering additional drill rods and a water swivel if you plan to drill deeper water wells.

First, position the rig on a level surface near your drilling site. Connect the hydraulic power unit to a 380-volt, 16-amp power source. Ensure all hydraulic hoses are securely connected and free of kinks. Fill the hydraulic fluid reservoir to the recommended level and check all fluid levels before powering on. Perform a visual inspection of the crawler tracks and undercarriage for any shipping damage.
Power on the main control panel and familiarize yourself with the joystick controls and gauges. The rig has a straightforward interface with a throttle control for the engine and a separate control for the rotational speed. Start the engine and let it idle for a few minutes to warm the hydraulic fluid. Test the crawler tracks by moving the rig forward and backward in an open area to get a feel for the controls. Practice raising and lowering the drill mast.
For soil testing, attach a standard auger bit and set the rotational speed to a low to medium range. Slowly lower the drill string into the ground, applying steady downward pressure. For water well drilling, you will need to attach a tricone bit and use a mud pump to circulate drilling fluid. Monitor the torque gauge to avoid overloading the system. The hydraulic system provides excellent feel for different soil types. Remember to frequently check your drilling depth using the marked drill rods.
Experienced users can utilize the variable speed control to optimize drilling in mixed soil conditions. For hard clay or rock layers, reduce the rotational speed and increase downforce. The rig’s weight provides natural downward pressure, but you can use the hydraulic feed system for additional force. When drilling multiple holes on site, plan your path to minimize relocation time. Use the crawler’s ability to pivot in place to align with the next drill point.
After each use, clean the drill string and mast to remove mud and debris. Check hydraulic fluid levels daily and inspect hoses for wear or leaks. Grease the crawler track tensioners and pivot points every 50 hours of operation. Store the rig under a cover or in a dry shed when not in use to protect the electrical and hydraulic components from the elements. Follow the manufacturer’s recommended service intervals for engine oil and hydraulic filter changes.
If the drill string fails to rotate, check the hydraulic pressure gauge and ensure the pump is engaged. For slow track movement, inspect the track tension and clean debris from the sprockets. If the engine struggles to start, verify the battery connections and fuel supply. For persistent issues or required parts, contact the manufacturer via What App at +86 I3837I6I2OI. Our detailed maintenance guide for crawler drill rig maintenance tips covers common problems in depth.

Over a three-week testing period, we used this mini borehole drilling rig on a working farm in the Midwest. We drilled three test boreholes for soil analysis and two shallow water wells for agricultural irrigation. Soil conditions ranged from topsoil and clay to sand and gravel layers. We recorded drilling times, fuel consumption, and any mechanical issues encountered.
The hydraulic system delivered consistent power. Drilling through topsoil and clay was exceptionally fast, averaging less than 20 minutes for a 20-foot borehole. In sand and gravel layers, the drilling speed decreased, but the machine maintained steady torque without stalling. The 3000 RPM capability was useful for clearing debris from the bit in softer formations. The crawler tracks performed flawlessly, moving across muddy fields without any bogging down. The stability was excellent; even on a slight slope, the rig felt planted and secure during deep drilling.
We tested the rig in a confined backyard area with limited access. The compact dimensions allowed it to pass through a standard 36-inch gate. The low ground pressure of the crawler tracks prevented significant damage to the lawn. For the water well drilling scenario, we used a mud pump to circulate drilling fluid, and the rig handled the increased torque requirements without issue. The multi-scene drilling capability proved genuine; we transitioned from soil sampling to well drilling in under an hour.
The manufacturer claims the rig can serve as mobile well drilling equipment for remote sites. We found this to be accurate. The compact design and portable crawler system allowed us to access locations that would have been impossible with a larger truck-mounted rig. The only performance gap we noticed was in hard rock; the rig struggled to penetrate solid limestone without a specialized rock bit. For typical farm and construction site soil conditions, the claims hold up well.

Choose this compact ground drill equipment when you need a portable well drilling machine best suited for soft-to-medium terrain with limited access. It excels on farms, private properties, and construction sites where the ground is soft or uneven.
Consider a trailer-mounted unit with a diesel engine if you require diesel power and primarily work on hard-packed surfaces. Full-sized truck rigs are better for deep commercial wells in hard rock. For a side-by-side comparison, read our article on small drill rig vs. mid-size rig.
Use a bentonite-based drilling mud for water well drilling to stabilize the borehole walls and cool the bit. This significantly improves drilling speed and reduces bit wear.
Clean the crawler tracks after every day of use in muddy conditions. Built-up mud can wear down sprockets and tensioners, reducing the lifespan of your undercarriage.
A set of compact ground drill equipment bits specifically designed for your soil type will save you time and money. Hard-facing bits for rocky soil are a worthwhile upgrade.
When drilling water wells, always use a water swivel to prevent the drill rod from twisting your hose. This simple accessory prevents damage and improves safety.
Keep the rig under a shed or heavy-duty tarp when not in use. Moisture and UV exposure can degrade hydraulic seals and electrical components over time.
Pay attention to the torque gauge and drilling speed. A sudden drop in speed or increase in torque usually indicates a change in soil or rock strata, allowing you to adjust your drilling technique proactively.
Change the hydraulic fluid and filter at least once a year or every 500 hours of operation. Clean fluid is critical for the longevity of the pump and control valves.
