  • Transmission case for tractors
    Patent number: 4528867
    Abstract: A transmission case for tractors consists of three parts, a front transmission case, a rear transmission case and a spacer transmission case, the spacer transmission case having a mounting flange around its outer periphery. The front and rear transmission cases are securely mounted to the mounting flange of the spacer transmission case so that the spacer transmission case is contained in either or both of the front and rear transmission cases thereby minimizing the entire length of the transmission case. The transmission case is also characterized in that the spacer transmission case has an opening in the ceiling to enable easy access to the gear components installed in the spacer transmission case during assembling work and adjustment.
