The company is still manufacturing heavy construction and agricultural equipment.
Hasegawa included one in 1/72 in their Emily kit (if I remember correctly).
"KATO TRACTORS - Equipment for: Heavy Lifting, Public Works, Farming.
Wheel or track tractors."
"Our company recommends with utter confidence this solid-tire-type vehicle able to pull super heavy objects."
"HEAVY! FORCE! KATO Tractors"
