Donnie :

Most excavtors use a "Industry Standard" SAE pattern.

Donnie :

(1) Stick Out

(2) Swing Right

(3) Stick In

(4) Swing Left

(5) Boom Lower

(6) Bucket Dump

(7) Boom Raise

(8) Bucket Close

(9) HOLD

(9a) Horn (If equipped)

(9b) Automatic Engine Speed Control Switch (If equipped)

(10) Seat

Donnie :

This is a CAT version of the same SAE pattern, the buttons could be different but, the lever operation is the same.

Donnie :

On versions that were changed to what some call John Deere or Backhoe Loader pattern, the boom control is on the left and the stick control is on the right.

Donnie :

Many more are out there but, these are the most common.
