An apparatus for analysing a sample of granular material, such as soil, is described. An elongated housing has a channel extending therethrough to define an optical path. A cavity is defined within the top of the housing to receive the sample, and a transparent sample-receiving surface is disposed within the cavity at a first elevation from the bottom of the housing. A lens assembly is positioned within the optical path at a second, lower, elevation. The lens assembly magnifies an image formed by light beams reflected by or transmitted through the sample. An image capturing device is disposed across the optical path at a third elevation that is lower than the second elevation. The image capturing device is thus lower than both the lens assembly and the transparent sample-receiving surface. A light source is mounted within the housing to emit light toward the sample-receiving surface.

Steering wheel adapter for agricultural vehicle vision guidance system

A vehicle guidance system for an agricultural vehicle is described which includes an optical imaging device collecting information of field characteristics, and a steering control device receiving the information of field characteristics transmitted from the optical imaging device. The steering control device having a steering actuator including a motor operatively connected to a hub adaptor. The hub adaptor is removably mountable to a central hub of a steering wheel of the agricultural vehicle in fixed rotary engagement, wherein when the hub adaptor is engaged to the central hub of the steering wheel, rotation of the hub adaptor by the motor causes corresponding rotation of the steering wheel. The steering control device thereby autonomously rotates the central hub of the steering wheel in response to the information of field characteristics received by the steering control device and the vehicle guidance system thereby steers the agricultural vehicle.

A soil analysis apparatus includes at least one sensor element for measuring a property of the soil; a blade assembly having at least one blade and being displaceable between a raised position and an excavation position, the at least one blade being operable to excavate the soil at a test location when the blade assembly is in the excavation position, the blade assembly being further operable to enter a sensor permitting configuration; and a first actuator operable to displace the at least one sensor element between an initial position and a sensing position along a sensor displacement path, the sensor element being proximate the soil at the test location when in the sensing position.
