Soil Probes


Oakfield Apparatus


Model DB-3 Tube Kit

The Oakfield line of soil sampling equipment has been used by professionals for nearly 50 years. Our record of providing quality products and customer service is recognized as outstanding in the industry.


The product line includes implements suitable for use by government agencies, Universities, growers, gardeners, for pesticide residue sampling and many other investigations. The convenience of interchangeable parts and the ability to attach tubes and augers to power equipment makes Oakfield products the most complete and utilized products today.


The DB-3 Tube Kit works best with moist coarse-to-medium textured soil. The probe works with heavy-type soils but a tool to punch out and scour the probe tube after each use. Not a good choice with hard, dry soil. If it is too hard to get the probe in the ground, consider the AMS power auger.





JMC Soil Samplers


JMC Backsaver Handle with Special Cleaner

Don't risk serious injury to your back, hands, or wrists. Pull samples easily with our JMC Backsaver Handle. Fitted with an 15 inch JMC Sampling Tube, this handle allows you to gather soil samples down to 43 inches. No bending over - handgrip stays at waist level throughout the sampling procedure.


Simply step down on the footpedal to plant your sampling tube. Then, bend your knees, grab the handgrip (now near waist level), and straighten your legs to lift the sampler out of the ground. Remove your sample with the JMC Special Cleaner and you are ready to sample again.


Insert the tube into the same hole in the ground. Step lightly on the footpedal to release the sliding rod inside the handle. Let 8 to 12 inches of the rod slide out of the handle. Then step down hard on the footpedal to lock the rod and drive the sampling tube further into the ground. When the tube is full (You can track depth by looking at the holes in the side of the Backsaver Handle), grab the handgrips and straighten your legs to lift the tube from the ground as you did before. When the handgrip gets too high, step lightly on the foot pedal and slide some of the rod back into the handle. Continue lifting the handgrips and adjusting the handle’s height as needed until the tube comes out of the ground. After cleaning the tube, either reenter the same hole for a deeper sample or move to a new site.


Our JMC Backsaver Handle fits a variety of soil sampling tubes. Each tube features a self-sharpening tip that pulls consistently good cores and outlasts common replaceable tips eight to one.
