It is very important to understand the physics of a CTL for this answer. The center of mass is about 60% rearward depending on the manufacture. A CTL consists on round front and rear idlers and they are actually recessed about 1/4" higher than bottom bogie wheels. This is so that when the track experiences a obstacle, the track wants to pull right over it. Now this makes a CTL inherently tippy front to rear. When you place a 2K lb attachment cantilevered off the front, the machine becomes very "toe tippy". Like when you pick something heavy with forks. The wheels are necessary to mitigate the machine from rocking. An added benefit, is now the cutting edge now only experiences 25% of what the CTL sees. This training video touches on this subject. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-wQuTSPUynCU.html Hope this helps!
