A hauling mat device for conveniently attaching to a hitch ball and hauling a load by dragging the device along the ground includes a sheet constructed of a resilient, flexible material having a pair of hitch holes extending through the sheet on each end edge of a pair of end edges of the sheet, wherein the pair of hitch holes are configured for receiving a hitch ball therethrough. The device is deployable in a first mode, wherein one of the hitch holes is hitched to the hitch ball and a load is placed on the sheet for hauling. The device is also deployable in a second mode, wherein both hitch holes are hitched to the hitch ball with the load placed in a loop defined by the sheet. In the first and second modes, the load is hauled by dragging the device along a ground surface.

A sail wheel includes a large wheel with a sail that is ridden on an outrigger attached to an axle of the large wheel. The outrigger includes a handle section and a foot stand section, allowing a user to ride and control the sail wheel. The sail wheel utilizes wind power for propulsion and is used on land for extreme sports or recreationally.

A physically-impaired-assisting multi-function sail comprises: a stanchion, a hoisting navigator for allowing an arthritic to deploy and retract the sail without the need to bend the fingers, a hoisting teeter totter secured to the navigator, a teeter-totter hook-lock secured to the teeter totter for automatically locking and unlocking the teeter totter to deploy and retract the sail, a cable secured to a camber, a cable canal formed into the teeter totter for hiding and protecting the cable within, a pivoting pulley housing secured to the teeter totter, a pivoting pulley hub swingingly attached to the pivoting pulley housing, sail-buttresses hingedly attached to the pivoting pulley hub, a sail canopy secured to the sail-buttresses, multiple cable pulleys rotatably secured at multiple locations within the pivoting pulley housing and pivoting pulley hub, a central tube attached to the pivoting pulley hub, sail-buttress-supporting arms hingedly attached to the sail-buttresses, and a shuttling hub attached to the sail-buttress-supporting arms.

The invention relates to the analysis of field characteristics to help determine prescriptions for crop input levels. A non-conductive enclosure houses a mapping system. The enclosure has a rectangular base and four walls extending from the base. A removable cover is received by the four walls. A foam interior receives at least one conductivity sensor. A port receives at least one electrical connection from an agricultural equipment in order to interface with the mapping system. A mounting assembly may mount the non-conductive enclosure to the agricultural equipment.

A sliding method on ice-surface aims at solve the problems of power output and poor durability and the difficulty in large-scale promotion. An ice-surface sliding tool includes a seat board, a U-shaped rod, sliding plates, H-shaped connecting frames, a pushing device, a hand-operated chain wheel and a reversing gear. One end of the upper end surface of the seat board is provided with a backrest. The U-shaped rod is provided on the side wall of the other end of the seat board. The lower end of the seat board is symmetrically provided with two sliding plates in parallel to each other. The sliding plates are connected with the lower end surface of the seat board through the H-shaped connecting frames. The pushing device is rotationally provided between the two H-shaped connecting frames. The hand-operated chain wheel is on the upper end of the U-shaped rod through a support bar.

An illustrated view of an exemplary sled for transporting items across difficult terrain is presented. The sled is useful for providing a means to transport belongings across a flat hard terrain to a desired location in an efficient and easy manner.

It is herein presented a novel transfer apparatus for a snowmobile, the transfer apparatus comprising a joint part and a support for a wheel. The joint part comprises an attachment hole for a ski bolt between a ski and a ski suspension of the snowmobile and a first coupling member for the detachable attachment of the support for the wheel and the support for the wheel comprises a second coupling member which is configured to connect to the first coupling member such that a detachable coupling is formed for the wheel.
