What’s Included in the Box

Upon delivery, the DIGMIGHT R350 arrives as a complete, ready-to-work unit. Our machine was securely crated and protected for shipping. The package includes the main excavator unit with the standard 0.08 m³ digging bucket already attached. Inside the cab, we found the operator’s manual and warranty documentation in a sealed plastic bag. Importantly, the machine comes with a full fluid complement—engine oil, hydraulic fluid, and coolant are all filled from the factory. There is no battery disconnect switch, so we recommend consulting the manual for proper pre-start checks. The build quality upon first inspection was impressive; welds looked clean and robust, hydraulic lines were neatly routed, and the paint finish was even and professional. No obvious missing components or assembly was required beyond removing shipping braces. This turn-key approach is a significant benefit, meaning you can theoretically unload it and begin work after a basic inspection and familiarization.

How to Use the DIGMIGHT R350: Complete Guide

Step 1: Initial Setup and Pre-Operation Inspection

Before starting, conduct a thorough walk-around. Check for any shipping damage, ensure all fluid levels (engine oil, coolant, hydraulic fluid) are correct, and inspect the tracks for proper tension. Verify that the battery connections are tight. This is also the time to familiarize yourself with the location of the emergency stop button, fire extinguisher (if equipped), and manual release valves for the hydraulics.

Step 2: First-Time Startup and Basic Controls

Enter the cab, fasten the seatbelt, and ensure the hydraulic lockout lever is engaged. Turn the key to the first position to activate the glow plugs for a few seconds (especially in cold weather), then turn to start. The Kubota engine should fire up smoothly. Let the machine idle for a few minutes to warm up. The pilot control levers operate the boom, arm, and bucket. The two foot pedals control left and right track movement independently for turning. Spend your first hour on a flat, open area practicing basic movements: driving forward/backward, swinging the house, and practicing digging and curling the bucket.

Step 3: Core Functions and Daily Digging Operation

For trenching, position the machine parallel to your trench line. Use the boom and arm to lower the bucket to the starting point, then use the bucket curl and arm draw functions together to take a bite. To dump, swing the house to the spoil pile, extend the arm, and curl the bucket open. The simultaneous function capability means you can lift, swing, and open the bucket in one fluid motion for efficient cycling. The machine’s power makes it easy to buy 3.5 ton mini excavator confidence for deep footings.

Step 4: Advanced Techniques for Grading and Lifting

For fine grading, use the flat edge of the bucket in combination with slight arm movements. The machine’s stability allows for precise control. When using the machine as a crane (within its rated capacity), always use the bucket to hook the load securely, keep the load as low as possible, and avoid swinging while traveling. The pilot controls offer the finesse needed for these delicate tasks.

Step 5: Essential Maintenance and Care

Daily: Check engine oil, coolant, hydraulic fluid, and clean the air pre-cleaner. Grease all fittings (boom, arm, bucket linkage, swing circle) every 8-10 hours of operation. Weekly: Inspect track tension and undercarriage for wear. Check for loose bolts or hydraulic leaks. Follow the engine manual for scheduled oil and filter changes (typically every 100-250 hours). Proper maintenance is key to making any 3.5 ton mini excavator worth it in the long run. For a detailed maintenance schedule, see our equipment care guide.

Step 6: Troubleshooting Common Issues

If the engine fails to start, check the battery connections and fuel shutoff solenoid. If hydraulic functions are slow or weak, check the fluid level and ensure the hydraulic lockout lever is fully disengaged. If the machine tracks unevenly, check for debris lodged in the sprockets or idlers. For persistent issues, always refer to the manual or contact DIGMIGHT R350 honest support through the retailer.

Performance & Real-World Testing

Testing Methodology

We operated the DIGMIGHT R350 over a three-week period on a mixed-use property, clocking approximately 50 hours. Tasks included digging a 100-foot drainage trench (24″ wide, 5′ deep), clearing rocky overburden, grading a driveway sub-base, and loading trucks with gravel. We evaluated power, stability, fuel consumption, operator comfort, and overall reliability.

Performance Metrics

The Kubota engine delivered consistent power with no noticeable lag or smoke, even when demanding simultaneous functions. Fuel consumption averaged 1.4 liters per hour, which is excellent for a machine of this capability. Hydraulic response was immediate and smooth, allowing for precise bucket control when backfilling and grading. The machine’s stability when lifting near its maximum capacity was reassuring, with minimal tipping sensation.

Real-World Scenarios

In the deep trenching scenario, the machine’s 91-inch depth was fully utilized. The digging force was ample to break through compacted clay layers. For the driveway grading, the pilot controls allowed for feather-light movements to achieve a smooth grade. The air-conditioned cab was invaluable during this hot-weather work, directly impacting productivity by allowing longer, more focused operating sessions. This real-world performance is what makes the debate of should I buy a 3.5 ton mini excavator tilt in favor of a model like this.

Claims vs. Reality

DIGMIGHT’s claims largely held up. The engine performance and fuel efficiency were as advertised. The digging depth and force were accurate. The air conditioning worked powerfully. One area where expectations slightly differed was in travel speed; while functional around a site, it is slow for moving long distances under its own power—a standard trait for excavators, but worth noting if you have large, spread-out sites without a trailer.
