  Heusler compounds having $\textit{D}$${}_{2d}$ crystal symmetry gained much
attention recently due to the stabilization of a vortex-like spin texture
called antiskyrmions in thin lamellae of Mn${}_{1.4}$Pt${}_{0.9}$Pd${}_{0.1}$Sn
as reported in the work of Nayak $\textit{et al.}$ [Nature (London) 548, 561
(2017)]. Here we show that bulk Mn${}_{1.4}$Pt${}_{0.9}$Pd${}_{0.1}$Sn
undergoes a spin-reorientation transition from a collinear ferromagnetic to a
noncollinear configuration of Mn moments below 135 K, which is accompanied by
the emergence of a topological Hall effect. We tune the topological Hall effect
in Pd and Rh substituted Mn${}_{1.4}$PtSn Heusler compounds by changing the
intrinsic magnetic properties and spin textures. A unique feature of the
present system is the observation of a zero-field topological Hall resistivity
with a sign change which indicates the robust formation of antiskyrmions.
