biggest pushback machine for a 737-700WL

[swaluver88]

im not sure why i always get the biggest pushback machine ment for A380s and T7 on my lightly loaded 737-700WL. it gets annoying, and i used to have the little one but since ive updated it just seems to be always big. is there someways to edit the CFG to have the smallest loader for the 737-700/800/900?
