Gear 150.38.104-4is the driven (crown) gear of the main drive of the T-150 tractor. In everyday life it is also known as "planetary". This is a massive bevel gear with the number of teeth Z=40, which is attached with 12 bolts to the differential housing axle. The driven wheel receives rotation from the drive shank and, through the differential, evenly distributes torque between the wheel axles.

There are two versions of this part - with holes for bolts with a diameter of 12 mm or 14 mm, depending on the configuration. If the driven gear 150.38.104-4 is installed together with the drive gear 150.38.103-2, then When assembled, they form a node under the designation 150.38.013, which is called main pair gears.
