Komatsu did D20S, D30S, D40S @ approx 4, 6, &, 9 Tonne, direct drive shovels. If I remember right these had a foot main clutch on the left, two long steering levers & a manual box, I think some had a pair of brake pedals for the right foot that could be applied singly or together JCB 3C style. When IH stopped the small manual machines about '75 or '76 (the B100, B125, BTD8) Komatsu had full page adverts in Construction news offering the above, saying they were re establishing direct drive in plant hire for its sheer simplicity & reliability. The Japanese believed that torque converters were only practical above 100 Hp, Japan had no oil deposits of its own & were much more worried about fuel consumption.
I have seen 941 powershifts with hand lever steering, but only read that direct drive 941's were offered but only built to special order. I gather the 951 dated from '61 & was oil cooled on all brakes & clutches from '64 on. Early 955's were about 9 tonne but went up in size from when the 951 was introduced at this weight. Oil main clutches were back fitted to some machines that would not have had them when new.
