- THIS paper describes an investigation into the best design of seat suspension for tractors having pneumatic tires with a rigid rear axle.Test results show that some of the factors entering into a good tractor supension include:
-
1.
A ratio between the natural frequency of the seat and the natural frequency of the tires of about 0.4 to 0.5.
-
2.
A supplementary seat deflection 1½ times the static seat deflection to avoid bottoming.
-
3.
Use of suspensions having nonlinear characteristics in order to hold seat deflection within practical limits.
-
4.
Adjustable seat-spring action to compensate for the varying weights of drivers.
