For the Soviet Union, the start of the Great Patriotic War happened at a very poor time. Yes, everyone knows about restructuring after purges and rebuilding fortifications at new borders, but few people know about another problem: a shortage of artillery tractors. Existing tractors no longer fully satisfied the RKKA, and projects to replace them haven't really taken off. The loss of major industrial centers during this time didn't help.
"To the chief of the GABTU Auto-Tractor Directorate
In a response to the inquiry by the 3rd department of the GABTU ATU, I report the list of artillery systems that require tractors for towing. Currently, factories do not produce any tractors to tow them, and it is impossible to replace them with foreign made tractors, as they are too weak.
In order to tow these guns, the Red Army artillery branch (newly formed regiments, high power regiments, front artillery regiments) needs 3300 tractors.
Additionally, no tractors are being built to tow guns that weigh less than 3000 kg. Currently, foreign wheeled tractors are being used for this task that, naturally, cannot be a good replacement for an artillery tractor.
6000 tractors are needed to towing guns that weigh less than 3 tons."
