Using a sample of 2.59×10⁷ psi(2S) decays collected by the CLEO-c detector, we present results of a search for the decay chain psi(2S)-->pi⁰h_c, h_c-->n(pi⁺pi^-)pi⁰, n=1, 2, 3. We observe no significant signals for n=1 and n=3 and set upper limits for the corresponding decay rates. First evidence for the decay h_c-->pi⁺pi^-pi⁺pi^-pi⁰ is presented, and a product branching fraction of B(psi(2S)-->h_cpi⁰)×B(h_c-->2(pi⁺pi^-)pi⁰)=1.88_-0.45-0.30^{+0.48 + 0.47}×10^-5 is measured. This result implies that h_c-->hadrons and h_c-->gammaeta_c have comparable rates, in agreement with expectations.
