I don’t think that’s true. It’s been quite a while since I read von Mellenthin’s Panzer Battles, but one of my take-aways from it was that you wanted to control the field after a tank battle so that you could repair your damaged (out-of-commission) tanks.
Hitler wasn’t willing to use production lines or unskilled workers to produce his war machines. Everything was designed and built by specialists. That’s why it took so much longer for them to produce their stuff. And because of that there weren’t spare parts readily available to repair them, and getting them to the field was difficult.
