Wi | As stated ISO is a pattern. Like anything ISO it is the international standard. IMO if you are new to operating and your other operator wants ISO pattern, spend the money to switch it. The nice thing about learning ISO is that no matter what you buy down the road you can have that pattern. Not necessarily on used machines, but every new machine can be ordered with ISO pattern. Many charge extra others have it standard.
Pilot is simply a type of control. When they first came out in skid steers most had the ISO pattern so everyone just associated Pilot controls with the ISO pattern. A pilot control is a simple precise way to operate. A lot of construction and mining equipment uses pilot hydraulics. Basically there is a low pressure pilot hydraulic system that runs to the controls, when you run the stick it operates a servo which sends fluid through the pilot circuit to operate the function you want. Its more precise than wires and a hydraulic leak is easier to find than a broken wire.
Newer machines are all going away from Pilot controls in favor of EH controls. They still have a ways to come on the EH controls as they are not as responsive and offer poor "feel" but they allow increase comfort by being mounted to the seat and most machines offering a pattern changer.
Since your machine has pilot controls you need to replumb the sticks in order to have ISO pattern. I am sure Gehl offers a kit you could price or just look at one and see about doing it yourself.
You will like the ISO pattern, especially if you are new. The reason it was chosen as the ISO pattern is due to its similarity to patterns in other equipment and the fact that new non-biased operators found it made the most sense and was easiest to learn. A lot of people who are used to older patterns have a hard time figuring out how to make one joystick do what two did before, but its not hard just takes some time. More people switch everyday. In our area Bobcat is actually the holdup, they do not want to sell any machines with their EH controls where most of the other brands have either phased out foot controls or pushed their customers towards EH controls. Deere now has EH foot controls which should be interesting. I wont argue that you can't beat the feedback and response from a manual control, but after about an hour of using every limb in your body to operate a skid steer you realize how nice the pilot and EH controls are. Plus with ISO pattern you can change radio station, HVAC settings, talk on the phone, etc while still driving without much effort.
If you have trouble learning it at first just put your right hand on the lap bar and drive around, once you need to operate the boom then take your hand off the bar and operate the boom. Eventually you will be able to blend it all together. | |
