We have studied quadrupole ordering and rattling in clathrate compound Pr3Pd20Ge6 using ultrasonic measurements. The softening were observed in temperature dependence of elastic constants C-11, (C-11 - C-12)/2 and C-44. The C-11 and (C-11 - C-12)/2 show minimums at 250 mK indicating a transition point to an antiferroquadrupole ordered phase due to a F3 doublet ground state at 8c site. Furthermore, the C-11, (C-11 - C-12)/2 and C-44 exhibit discontinuitive anomalies at 60 mK revealing a ferroquadrupole ordering due to a F-5 triplet ground state at 4a site. Two distinctive ultrasonic dispersions caused by thermally activated F-5-type rattling were observed in C-44 around 15 K and 25 K.
