Abstract: We show that the KdV6 equation recently studied in 1,2 is equivalent to theRosochatius deformation of KdV equation with self-consistent sourcesRD-KdVESCS recently presented in 9. The $t$-type bi-Hamiltonian formalismof KdV6 equation RD-KdVESCS is constructed by taking $x$ as evolutionparameter. Some new solutions of KdV6 equation, such as soliton, positon andnegaton solution, are presented.
