Loader Mast Latching System

The goal is to hitch and unhitch a loader to the tractor with only one driver trip out of the tractor. This means that the operator has to leave the cabin only once in order to move the mast latch lever and to unlatch the mast from the mounting frame. After having unlatched the loader the loader has to be moved away from the mounting frame, wherein the mast latch lever or a latch has to be kept in an unlatched position or disengaged during this moving sequence. Furthermore it is desired to have the latch on the same time ready for the next engagement or hitching sequence without any additional action. As a further objective it is always desired to keep a system as simple and reliable as possible and to keep the masts locked during the loader work. With respect to the above a loader latching system comprises a pin, a latch, a trigger, 2 springs and a lever according to the pictures below.

In the unhitching sequence, the spring loaded latch is manually disengaged and stays in this position because of a spring loaded trigger engaged on the top of the mounting frame. That allows the operator to move the tractor away from the loader for unhitching.

During the hitching sequence, because of its pin position, the trigger stays in the disengaged position when the mounting frame slides inside the loader mast. As soon as the correct position of latching is reached between the loader mast and the mounting frame the latch engages itself thanks to...
