evener n
1 On a horse-drawn vehicle: a pivoting bar or set of bars used to transmit the force from two or more singletrees to the vehicle; sometimes the whole apparatus including the singletrees. Note: A few DARE and LAUM Infs appear to use evener in the same sense as singletree n or even to interchange their senses; it is unclear whether this is an established usage or merely reflects lack of familiarity with the implements.
