In this paper the system of three dynamic equations with neutral termin the following form$$\left\{\begin{array}{l}( x (t) + p(t)  x (u_1 (t) )  )^\delta= a(t)  f (y(u_2(t)))\\y^\delta (t) = b(t) g (z( u_3(t) )  )\\z^\delta(t)= c(t) h( x( u_4(t) )  )\right.\end{array}$$on time scales is considered. The aim of this paper is to present sucientconditions for the existence of positive bounded positive solutions of theconsidered system for 0 < p(t) const < 1. The main tool of the proofof presented here result is Krasnoselskii's xed point theorem. Also, theuseful generalization of the Arzela-Ascoli theorem on times scales to thethree dimensional case is proved.
