The invention discloses a roller tractor rear balance weight which comprises a first balance weight block and a second balance weight block. The first balance weight block is provided with a center hole. Eight bolt positioning holes evenly distributed along the circumference are formed in the edge of the center hole. Two symmetric bolt positioning holes of the eight bolt positioning holes are in a semi-circular notch shape and used for installing a spacer bush. The other six bolt positioning holes are round holes used for installing bolts. The outer side face of the first balance weight block is provided with three grooves evenly distributed along the circumference. Threaded holes are formed in the circle centers of the grooves of the first balance weight block. Six grooves evenly distributed along the circumference are formed in the outer side of the second balance weight block. Protrusions are arranged opposite to three spaced grooves of the six grooves, the protrusions on the second balance weight block adjacent to the first balance weight block correspond to the grooves of the first balance weight block, and positioning holes are further formed in the circle centers of the grooves of the second balance weight block. Two small planes are symmetrically arranged along the outer circumference of the second balance weight block and used for assembling rear receding valves. The roller tractor rear balance weight is reasonable and simple in structural design, reliable in positioning and convenient to disassemble and assemble, balance weights with different weights can be selectively installed according to requirements, and different practical work requirements are met.
