Accepted: 6 July 1998
We investigate the time evolution of two different (GOY-like) shell models which have been recently proposed to describe the gross features of MHD turbulence. We see that, even if they are formally of the same type sharing with MHD equations quadratic couplings and conserved quantities, differences exist which are related to conserved quantities.
