Claims

[Scope of utility model registration request]

A front wheel drive shaft 16 installed outside the mission case 17 is connected to the front wheel power transmission shaft 14 horizontally suspended in the mission case 17 through an opening 18 in the middle of the mission case 17 in the front-rear direction. This is a structure of a front wheel drive unit of an agricultural tractor that is interlocked and connected via 2
3, the opening 18 to the mission case 17
a driven gear 25 removably attached to the transmission shaft 14 in a state where it can be inserted and removed from the transmission gear 23, and meshed with the transmission gear 23;
A rotary shaft 24 to which the driven gear base 5 is removably attached and whose distal end is separably connected to the drive shaft 16 is removably installed in a case 21 protruding from the mission case 17. and the case 21,
a rear end side portion 2.1a that supports the rear end side of the rotating shaft 24 and is integrally configured with the transmission case 17;
A front wheel drive unit for an agricultural tractor, comprising a front end portion 21b that supports the front end side of the rotating shaft 24 and is removably connected to the transmission case 17 and the rear end portion 21a. structure.
