Animal drawn adjustable implement cart

A two wheeled, height adjustable work platform for pulling farm implements that perform field work, comprising:

• a pair of spaced-apart main frame members with each main frame member connected to, and extending upwardly from, the axles of each respective wheel;
• a pair of upper sprockets with each upper sprocket mounted at the upper end of each main frame member and a pair of lower sprockets with each lower sprocket rotatably mounted coaxially to each respective wheel axle adjacent the lower end of each main frame member;
• the work platform for disposition on the main frame members including:
• a pair of intermediate frame members with each intermediate frame member mounted on each respective main frame member for slidable movement thereon between an elevated position and lowermost position, the intermediate slidable members interconnected by a cross bar for unitary slidable movement on the main frame members;
• two pairs of intermediate idler sprockets with each pair of intermediate idler sprockets attached to each intermediate frame member;
• a pair of continuous chains with each continuous chain entrained on one set of upper and lower sprockets and one pair of intermediate idler sprockets and the chains being rotatably driven by the rotation of the wheels;
• a brake pedal mounted to the cross bar and linked to both sets of intermediate idler sprockets so that depression of the brake pedal causes at least one intermediate idler sprocket from each pair to move into a locking position thus limiting the free rotation of the chains but not the wheels;
• a pair of locking and releasing pins for locking the intermediate frame members to the main frame members for maintaining the work platform in the elevated position and for retraction therefrom so that the work platform can descend on the main frame members to the lowermost position;
• and
• a pin releasing pedal mounted to the crossbar and linked to the locking and releasing pins so that depression of the pin releasing pedal actuates the retraction of the pins from the intermediate frame members and the main frame members thereby allowing the intermediate frame members to slide on the main frame members for allowing the work platform to move from the elevated position to the lowermost position.

A two wheeled, height adjustable cart manually adjustable between an elevated position and a lowermost position for pulling work implements, comprising:

• a pair of spaced-apart main frame members mounted on and extending upwardly from the axle of each respective wheel;
• a work platform mounted on the main frame members and capable of selective reciprocable movement between the elevated position and the lowermost position in order to raise and lower the work implements and to maintain the stability of the work platform;
• the work platform including a pair of intermediate frame members with each intermediate frame member being slidably mounted on each respective main frame member for movement between the elevated position and the lowermost position and the intermediate frame members being shorter in length than the main frame members;
• and
• a pair of locking and releasing pins with each pin mounted to each intermediate frame member for locking the intermediate frame members to the main frame members when the work platform has been raised to the elevated position in order to maintain the work platform at the elevated position and for releasing the intermediate frame members from the main frame members so that the intermediate frame members can slide downward on the main frame members for setting the work platform at the lowermost position.
