Obs. rare. [First element obscure; second element TREE.] A name used by Markham and Surflet for the main swingletree of a plough, to the end of which are attached the two smaller swingletrees or whipple-trees, to which the two horses or oxen are harnessed.
In the Eng. Husbandman Markham appears to use the term as equivalent to swingletree, calling the main swingletree the first or hindmost toastree.
