A) Get the number of teeth on the output shaft on the tractor(ex1). If it doesn't have teeth get the Key width(ex3).B) Next get the diameter of the output shaft on the tractor. (ex2, ex 4)
C) Now the number of teeth on the output shaft on the machine(ex1). If it doesn't have teeth get the Key width(ex3).
D) Next get the diameter of the output shaft on the machine. (ex2, ex 4)
E) Now Get the Collapsed Measurement. (this is when the shaft is at its shortest position)
F) Now get the extended position. (this is when the shaft is at its longest position)
