  New data on the production of single neutral pions in the
$pd\rightarrow{}^3\textrm{He}\,\pi^0$ reaction are presented. For fifteen
proton beam momenta between $p_p=1.60\;\textrm{GeV}/c$ and
$p_p=1.74\;\textrm{GeV}/c$, differential cross sections are determined over a
large fraction of the backward hemisphere. Since the only previous systematic
measurements of single-pion production at these energies were made in collinear
kinematics, the present work constitutes a significant extension of the current
knowledge on this reaction. Even this far above the production threshold,
significant changes are found in the behaviour of the angular distributions
over small intervals in beam momentum.
