Abstract
It is shown that solvable mixed spin ladder models can be constructed from su(N) permutators. Heisenberg rung interactions appear as chemical potentia l terms in the Bethe Ansatz solution. Explicit examples given are a mixed s pin-1/2 spin-1 ladder a mixed spin-1/2 spin-2/3 ladder and a spin-1 ladder with biquadratic interactions.
