Abstract: An apparatus is disclosed which is mountable upon a tractor for removing stakes from the ground and for collecting the stakes. The apparatus includes a support framework and a stake loosening means disposed on the framework. The stake loosening means includes a plurality of stake loosening fingers for loosening the stakes relative to the ground. The loosened stakes are removed from the ground by counterrotating rollers which define a stake receiving passage therebetween. The stakes are guided from the counterrotating rollers by means of a stake guiding chute having an input and an output end with the output end being disposed adjacent a stake collecting means.

Abstract: Catamaran boat dollies are provided, one for each of the hulls of a catamaran, for moving the catamaran along a beach or other supporting surface. Each dolly has a cradle mounted on a single wheel, the axis of the wheel axle declining outwardly from the cradle to define an included angle with the vertical of approximately 75.degree.. Longitudinal bars of the cradle embrace opposite sides of the associated hull, and the disposition of the wheel and its axle results in a bending or rotational moment which causes the cradle to clampingly engage the hull. Because of the shape of a fourteen or sixteen foot "Hobie" type hull, the catamaran will remain in satisfactory engagement with the dollies as it is moved across the surface, but is preferably provided with a tie-down band for retaining the dolly in place as the catamaran is moved into or out of the water. For a "Sizzler" or "Prindle" type hull the cradle has opposed bars which engage opposite sides of a metal keel, and a tie-down band is provided for preventing the hulls from bouncing from between these bars. A protective coating such as polyvinyl-chloride preferably covers the cradle and other parts of the dolly to protect metal of the dolly and to protect the hulls from abrasion.
