We give a systematic way to compute higher orders in the 1/m_b expansion ininclusive semi-leptonic decays at tree level. We reproduce the known 1/m_b^3terms and compute the 1/m_b^4 terms at tree level. The appearingnon-perturbative parameters and the impact on the determination of V_{cb} arediscussed.Comment: 23 pages, 3 figures, uses phystex.st
