Politiki yinkunga cyangwa amategeko yinkunga nibyingenzi, ariko ntabwo byose. Hariho izindi mpamvu zituma ubwinshi bwa chassis nto. Kurugero, nkuko umubare wa romoruki wikoreshwa ukomeza kwiyongera, impuzandengo ya buri gihe kuri traktosi idahagije. RACORIA ZASHOBORA GUKORA GUSA UMUNSI MUKWE MU MWAKA. Ku ruhande rumwe, birahenze cyane kubakoresha kugura chassis nto. Kurundi ruhande, hamwe nakazi kadahagije, inshuro mbi ni make, kandi abakoresha ntibakunze kubona ibibazo bikomeye nimashini. Haracyarimo ibice byinshi bikoreshwa gusa mu gutwara, kubiba, imiti izenguruka no kuyobora imirima. Ntibakeneye gutwara imitwaro iremereye, bityo bafite imbaraga zo mu mafarashi nyinshi ariko ntibafite ibisabwa byinshi kumubiri wa moteri kandi ntibakunze kugira ibibazo.
Nubwo abashinzwe imirima mito bafitanye isano n'imibereho yabo, ntibashobora guhisha "icyaha cyabo cy'umwimerere" cyo kunyereza amanota no gutsinda amafaranga y'inganda za Leta, kuko uyu munyururu w'inganda uhisha ibintu byinshi bidashobora guhura n'umucyo. Kurugero, amafaranga yatanzwe nibiciro yarahinduwe. Hariho n'imanza aho abacuruza bagombaga gutanga amafaranga kubakoresha igihe baguze imashini. Niba aribyo aribyo bibazo byonyine, byaba ari byo gusa. "Ikibi" kinini cya chassis nto ni "amafaranga mabi yirukana amafaranga meza", ni ukuvuga ko habayemo umubare munini wa thEssis ntoya yatwaye umubare munini wa chassis hamwe na romoruki zikomeye za chassis mu isoko. Ibi bituma bidashoboka ko abakora bashaka gukora ibicuruzwa byiza kugirango babeho, ntibabitabira uretse "kujyana nurujya n'uruza".
