The controls are responsive, and the machine turns on its tracks with surprising agility.
For soil testing, position the rig directly over your marked spot. Engage the hydraulic downforce slowly to allow the auger to bite into the ground. As the bit penetrates, maintain a steady rotation speed. For water wells, the process is identical but requires adding drill stems to reach depth. The key is to avoid forcing the bit; let the hydraulics do the work. During our tests, this best portable borehole drilling machine maintained consistent performance.
Professionals can utilize the machine’s variable downforce. By adjusting the pressure slider, you can maintain a constant drilling speed through varying soil densities. For core sampling, use a specialized core barrel attachment. The smooth hydraulic system allows for the careful extraction of intact soil samples without compromising their structure.
Daily maintenance is vital. After each use, clean all drilling mud off the mast and tracks. Lubricate the moving parts of the drill head and the track rollers. Weekly, check the hydraulic fluid level and inspect hoses for wear. The robust steel construction will last for years if you keep it greased and clean. This rig is a workhorse, but it needs care to remain reliable.
If the drill bit stops turning under load, first check the hydraulic fluid level and the condition of the pressure relief valve. If the crawler tracks are slipping, clean the sprockets of mud. Most operational issues stem from user error or neglected maintenance. For persistent problems, the manufacturer’s support is responsive.
