Magnetic anisotropy of $Lu_2Co_{17-x}Si_x$ single crystals grown by the Czochralski method was investigated. The homogeneity range of Si substitution for Co extends up to x = 3.4 in $Lu_2Co_{17-x}Si_x$ solid solutions. The unit cell volume, Curie temperature, and spontaneous magnetic moment decrease monotonously with increasing Si content. $Lu_2Co_{17}$ has the easy-plane type of magnetic anisotropy in the ground state, which changes into the easy-axis type by two spin-reorientation transitions of the second-order, the easy-plane-easy-cone at $T_{SR1}$~680 K and the easy-cone - easy-axis at $T_{SR2}$~730 K. Upon Si substitution, the observed spin-reorientations shift towards the lower temperatures for $Lu_2Co_{17-x}Si_x$ $(T_{SR1}$~75 K and $T_{SR2}$~130 K in $Lu_2Co_{16}Si$) and vanish for compounds with 1
