    Kubotas 1st skid machine will be out this fall! If its built like their tractors there will be a serious new player in the game!

    that sounds good..........

    hope you can switch them from case to cat.........

    there excavators are great machines......... hope the skidsteers are the same..........

    Don't you think it would look kinda akward? What will it look like? Radial, or vertical lift?

    If they do run pilot controls and they do have a selector switch from CASE to CAT, hopefully they put more thought into it than Komatsu. They currently run pilots and have a selector switch. The problem is by having a switch only, you make all pressures the same for all functions (drive, loader and bucket). They don't run very well that way. If a switch is used to go back and forth than they have to come up with a way to make the pressures and flow variable for the different functions. E/H does not have this issue as it is electronic not hyd. valve related. Course E/H may have other issues but this one it does work for.

    Pilot controls with a valve for changing patterns from ISO to H (CAT to CASE) requires that all flows and pressures be the same because to have the ability to change with the turn of switch all inputs must be the same. This means the drive, loader and bucket functions cant be tailored to their optimium settings. If the drive wheels require xxx number of psi or flow and the loader functions yyy number of psi or flow a medium must be struck to allow the operator to go from one pattern to the other. That medium is not necessarily the optimium setting for the best performance. It is balance struck to allow for the pattern changer.

    E/H does not have this issue......disregard .... does the pilot explaination make sense?

    If this does not Tigerotor will need to step in. He is much more elequent than am I.

    I will add one last thing. Every OEM that offers pilots has a field installed kit to change the pattern from the one that the machine came with to the other. So if the machine came with ISO you can switch to H (usually done by a field tech.) The reason is the kit to change the pattern is made to optimize the psi and flow for the new pattern. Only Komatsu has utilized pilots with a pattern changer on the machine. It has not been copied because no one else is happy with the results of the pattern changer. Skid steers are different than mini excavators which have had pattern changers for years. The drive of the excavators remains unchanged when changing patterns, not so of course with a skid steer. Typically the drive of an excavator has its own pump to supply the drives so don't be confused by what is done on a mini ex verse a skid steer. They are different animals entirely.
