While grousers are frequently arranged to provide 'a road en» comprises two generally semi-circular members, one being adapted to be disposed over the lugs of one rowwhile the other ‘member is adapted to be disposed over lugs of an adjacent row, where gaging surface which is continuous sogfar as by, the members are spaced apart axially, but 15 lying in a cylinder is concerned, most. lugs, par-' their ends overlap so as to provide a continuous ticularly spade lugs, tend to destroy the road road engaging surface.- By the use of a con-. surface over which the machine‘ moves.
