Two reasons:
The material, labor and transportation used to mine, process, design, cast, form, and finish the old equipment is already spent. The only reason to recycle these materials is if the reprocessing results in a machine that is so much more reliable, economical/efficient, and long lasting, that the new expense is worth the added degradation to the environment. There are tractrs and construction equipment that are 50 years old doing the same tasks that new ones might do. Again only if they are so inefficient and polluting should they be scrapped.
This rationalle might be needing to be revisited if science and technology seriously improve on the efficiency, and resource use of production machines for transportation and Ag. None with that needed 50 percent improvement is available. Look at the 1900 to 1950 tractors. They were (opinion) far from efficient or friendly for 8 hour days. They are not used as serious production machines any more. When a revolution in technology takes place, then the reuse of the material in these newer old machines would make sense (see reason 2)
The other reason is to preserve heritage. Sufficient operating machines need to be kept such that we remember where we come from. James A.

When Push Comes to Shove - by Dave Patterson. When I was a “kid” (still am to a deree) about two I guess, my parents couldn’t find me one day. They were horrified (we lived by the railroad), my mother thought the worst: "He’s been run over by a train, he’s gone forever!" Where did they find me? Perched up on the seat of the tractor. I’d probably plowed about 3000 acres (in my head anyway) by the time they found me. This is where my love for tractors started and has only gotten worse in my tender 50 yrs on this “green planet”. I’m par
