In this article, we study the form of deviation of geodesics (tidal forces)and Raychaudhuri equation in a Schwarzshild-Finsler-Randers (SFR) spacetimewhich has been investigated in previous papers. This model is obtained byconsidering the structure of a Lorentz tangent bundle of spacetime and inparticular the kind of the curvatures in generalized metric spaces where thereis more than one curvature tensor, such as Finsler-like spacetimes. In thesecases, the concept of the Raychaudhuri equation is extended with extra termsand degrees of freedom from the dependence of internal variables as thevelocity or an anisotropic vector field. Additionally, we investigate someconsequences of the weak field limit on the spacetime under consideration andstudy the Newtonian limit equations which include a generalization of thePoisson equation.
