Best Mode for Carrying Out the Invention Referring to the drawing~~ and the appended claims, an apparatus 100 is disclo~~ed suitable for use in determining information at a forestry site 106 for harvesting of trees. With particular reference to Figs. 1 and 2, the apparatus 100 i:~ embodied as a mobile machine 102. More particularly, the mobile machine 102 is a mobile cruiser machine 104, adapted to traverse the forestry site 106 efficiently and reliably. Although the mobile cruiser machine 104 of Figs. 1 and 2 is illustrated in a certain manner, it is understood that many variations in the design and construction of the mobile cruiser machine 104 may be employed without deviating from the: spirit and scope of the present invention.
In the preferred embodiment, the mobile cruiser machine 104 has a narrow width and a low height, and is adapted for one operator. The low and narrow profile of the mobile cruiser machine 104 allows for traversal of a forestry site 106 which is too dense and rugged for traversal by other vehicles.
The design of the mobile cruiser machine 104, as described below, allows for movement over rugged terrain.
l0 Referring to Fig. 4, the mobile cruiser machine 104 includes a primary power source 402, preferably an engine 404, a set of ground engaging members 406 drivably connected to t:he primary power source 402, and means 410 for steering the mobile cruiser machine 104.
In the preferred embodiment, and as illustrated in Figs. 1 and 2, the set of ground engaging members 406 is a set of belted tracks 408.
The set of belted tracks 408 offers the advantages of excellent traction and reduced impact on the terrain.

Referring back to Figs. 1 and 2, a gimbal base 108, mounted on the mobile cruiser machine 104, includes a set of gimbals 118. The gimbals 118 are adapted to maintain a constant orientation with respect to a horizontal plane as th.e mobile cruiser machine 104 traverses the forestry site 106. In addition, the gimbals 118 are adapted to sense a slope of the mobile cruiser machine 104, the slope of the mobile cruiser machine 104 being determinative of the to slope of the terrain at the forestry site 106. A set of slope value signals, generated by the gimbals 118, are delivered to a slope determining system to determine the slope of the terrain as the mobile cruiser machine 104 traverses the forestry site 106.
In the preferred embodiment, as depicted in Fig. 3, the gimbals 118 are arranged to sense a slope on two orthogonal, horizontal axes 302,304. In this configuration, the gimbals 118 function as a two-axis inclinometer, thus providing a true indication of the slope of the terrain regardless of the heading and orientation of the mobile cruiser machine 104.
