On the newer models, you can switch from ISO to SAE or visa versa, depending on what you have (it looks like you have ISO controls currently, the right hand control, curled in, closes the bucket, also known as John Deere control). It doesn't matter if you have a Deere or a CAT or any other machine, the systems are set up differently. Some people prefer the SAE (backhoe/CAT controls) over the ISO (excavator/Deere controls)
On the computer panel in the cab of the machine, you can go into the menu and change the controls.

Try both to see which one you're more comfortable with. Personally, I like the ISO.
