In real life, the tracked loader just makes a mess ie, likes to dig it's self a hole with the tracks in tight spaces ( some operators like to doo that in a large space too
) We've owned 2 both dressers/IH 100E and a 175C . Dad still has the 100E but still barely gets used . THe excavators and dozers where always our prime machines . Excavators always dug basements out faster and cleaner with the dozer dressing the bottom and pushin the spoil off/away. As for a rubber tired loader, why you think they're used in the quarry
