Hydraulic Soil Sampling Equipment

AGVISE Laboratories has been manufacturing and distributing soil sampling equipment for more than 25 years. During that time our staff has used personal sampling experience to design heavy duty hydraulic sampling systems. With customers from all over the U.S. and Canada, we have equipment to cover the needs of all our customers. Some customers require equipment that can sample to 24” and others need to sample down to 48”. AGVISE also distributes hand sampling equipment from other manufacturers.


24” Electric/Hydraulic Soil Sampling System (Complete Unit)
This hydraulic sampling system is designed to collect 0-6” and 6-24” soil samples. The system is powered by an electric over hydraulic power system. The full cycle time for the system is 10-12 seconds (down and up). This system will push through about 10-15 inches of frost when mounted inside the truck cab. This system is designed to be mounted inside the cab of a truck, but it can also be mounted outside if you prefer. The 30” cylinder is already mounted on a channel iron. To mount the cylinder inside the cab, find an area 6” by 6” where the soil probe can go through between the frame and the exhaust system of the truck. Then cut a 6” by 6” hole in the floor of the truck. Bolt a cross member to both sides of the frame, just to the side of the hole above. Then put the cylinder through a 6” hole in the floor and bolt the channel iron to the cross member. Place the 6” hole as close to the driver as possible so he doesn’t have to reach very far to attach the soil probe to the cylinder. The power unit should be attached to the floor in the box of the truck. The power unit can also be installed in the cab under the back seat. Hoses should run from the power unit to the cylinder through the hole in the floor of the cab. Be sure to use Quicktatch couplers on the hoses so the cylinder and the power unit can be easily removed and stored in a dry area for the winter. This sampling system includes the 12-volt power system with controls and power cables, a 30” hydraulic cylinder attached to a channel iron, 2 stainless steel probe bodies (one slotted and one solid), two screw on tips (one wet and one ¾” soil tip), one heavy duty oversize probe body and tip and a cleaning brush and handle.  Additional parts included are spare electric solenoid, spare hydraulic solenoid and spare two-button control box.


Probe Tips Available (pictured left to right)

HD OS tip, wet tip, ¾” tip, 5/8” tip, ½” tip


Stainless Steel Probe Body And Cleaning Brush

Probe bodies are available in solid or slotted models. The Quicktach collar is supplied with each probe body. A cleaning brush handle and a replaceable nylon brush are available for probe cleaning.


Heavy Duty-Oversize Probe And Tip

This new probe body and tip are made from a very hard metal (chromoly steel aircraft tubing). This probe and tip were designed specifically for very wet sticky soils but also work very well in frozen or dry soil conditions.


Gas Motor Power System

This power system has a Honda Motor (6 or 8 hp) and a large capacity hydraulic pump and tank. This power system can be used with either the 30” cylinder or larger cylinders which required a larger reservoir. This system has an electric start, which can be remotely located in the truck cab.  This power system is required for telescoping cylinders (40-48” sampling) because of the increased flow rate required. Deep sampling (40-48”) may be necessary for sugar beets and other deep rooted crops)


Quicktatch™ Collar

A Quicktatch collar is supplied with each probe body. The Quicktatch collar must be welded to the probe body once sufficient clearance under the truck is determined. This special collar allows you to quickly attach and remove the soil probe from the hydraulic cylinder.

Cylinder Mounting Bracket

Cylinder Mounting Bracket

This bracket can be used for fastening the 30” cylinder from the sampling system to the truck frame under the cab. The 30” cylinder in the sampling system is already bolted into a channel iron when you receive it. The channel iron holding the cylinder will be bolted to the yellow bracket underneath the cab of the truck to hold the cylinder in place. The blue cross member is 2” by 5” by 54” (long enough for any truck frame). The blue cross member should be cut and bolted up inside frame to maintain ground clearance.
