It has a pre-select Praga-Wilson gearbox, (5 forward +1 reverse gears.) A gear is selected using the gear stick then when the gear is required the left pedal (gear change action/clutch combined) is pressed to the floor, giving a hiss of air sound, on release of the pedal the dry plate clutch engages after about half the return spring controlled movement.

The gearbox was manufactured by Praga Hostivař. The OT-64's engine, transmission, suspension and axles were produced in Czechoslovakia. Today they are gradually being replaced by newer vehicles. Later, after introducing the BMP-1 infantry fighting vehicles into service, SKOT transporters were exported to other countries.

They were also acquired by the Hungarian army. Of the 4,500 OT-64s produced, 2,500 of them were obtained by the Polish army, and 2,000 of them by the Czechoslovak army. Armored hulls and towers (Huta in Ostrowiec Świętokrzyski and Huta Częstochowa), elements of the suspension system (Huta Stalowa Wola) and on-board armaments (Zakłady Mechaniczne in Tarnów) were manufactured in Poland.

Components of the propulsion system and power transmission (engine Tatra, transmission Praga and chassis) were imported from Czechoslovakia. The Polish plant acted as an assembly plant. Serial production of the transporter started at FSC in Lublin (Poland) on October 12, 1963.

In 1961 the first sample series were built and starting from October 1963 the vehicles were produced in Lublin, Poland by Fabryka Samochodów Ciężarowych. OT-64 was intended to replace the halftrack OT-810, which was nearly identical to the German Sd.Kfz. The work resulted in the KTO Ryś prepared by Wojskowe Zakłady Mechaniczne No. In 2002, the modernization of the SKOT transporter began in Poland. Until the early 1970s Czechoslovakia and Poland produced around 4,500 OT-64 SKOTs of all variants, just under a third of which were exported. The OT-64 SKOT ( Czech acronym for: Střední Kolový Obrněný Transportér, and/or Polish Średni Kołowy Opancerzony Transporter – medium wheeled armoured transporter) is an amphibious armored personnel carrier ( 8x8), developed jointly by Poland ( PRL) and Czechoslovakia ( ČSSR) well into the 1960s.
