Acco super bulldozer

I was going to publish this in the last month, but my water cooler broke and then i had to buy another one that took 1 month to come. Anyways this is my first project and i hope you guys like it, also, my interiors aren't the best. Please tell me what can i change to make it better. In the early 1980s, Umberto Acco, an entrepreneur and owner of a civil construction company in Portogruaro, northern Italy, received a job that would require his company to build a custom crawler dozer and motor grader. The machines needed to be big — really big — and were intended to be used on a project that involved moving earth — lots of earth — in large, desert areas. While many components of the dozer had to be custom made, including the blade, Acco used mainly Caterpillar parts to build what has become known as 'Super Dozer'— the world's largest bulldozer. How Big Is Big? The specs for the more-than-40-ft., 183-metric tons/201-short tons crawler dozer are dizzying. Two 8-cylinder, 675 hp Caterpillar diesel engines combine for a 1,350 hp output. The blade measures 23 ft. wide and 9 ft. high. The rear ripper (a claw-like device) measures 10 ft. and is powered by hydraulic rams. The tracks were custom made by Berco. The transmission operates through two drive sprockets for each track to create torque generated from the engines. The brakes and control mechanisms are operated hydraulically. This massive piece of iron was the only one of its kind produced. HOW TO USE: ALWAYS use the 2nd gear to move forward, it's less buggy, also you need a decent machine to run this, because it runs better at 55+ fps, and avoid rough terrain, try to use it only on straight surfaces. You can use without god mode, but it's better to use it. Blade controls: PgUp/PgDown to lift the blade Alt+PgUp/Pgdown to move the blade Ripper controls: Alt+W to lower the ripper and Alt+S to bring it up Alt+A to move it forward and Alt+D to move it backwards
