[Bobcatt643]

Hello. First of all sry for my english. So I have a bobcat 643 its running good but I'm wondering what is this thing at the engine compartment, It is conected to the hydraulic system and its spining all the time. There is a switch to stop it but the engine statrs to lose rpm. The other thing looking strange is the back door, it seems to be OEM like that becouse there are no welds onli curvd like that. I wondering if this is something that i wont use, to make a auger attachment with this motor if it is capable for this purpose. I will be thankful if someone of you know and tell me whats the purpes of this thin it lookint to be OEM like that. http://www.skidsteerforum.com/DesktopDefault.aspx?tabid=52&gallerypage=1&currentitem=3&path=643%20bobcat http://www.skidsteerforum.com/DesktopDefault.aspx?tabid=52&gallerypage=1&currentitem=4&path=643%20bobcat http://www.skidsteerforum.com/DesktopDefault.aspx?tabid=52&gallerypage=1&currentitem=5&path=643%20bobcat http://www.skidsteerforum.com/DesktopDefault.aspx?tabid=52&gallerypage=1&currentitem=6&path=643%20bobcat http://www.skidsteerforum.com/DesktopDefault.aspx?tabid=52&gallerypage=1&currentitem=9&path=643%20bobcat http://www.skidsteerforum.com/DesktopDefault.aspx?tabid=52&gallerypage=1&currentitem=8&path=643%20bobcat http://www.skidsteerforum.com/DesktopDefault.aspx?tabid=52&gallerypage=1&currentitem=7&path=643%20bobcat http://www.skidsteerforum.com/DesktopDefault.aspx?tabid=52&gallerypage=1&currentitem=2&path=643%20bobcat

That's not something you see everyday.... It looks like someone has installed a rear PTO on your machine. That is a hydraulic motor.
I wonder if it's hooked up to your aux hydraulics, grab the right steering lever, pull it all the way to the left then let it go. See if the motor stops spinning.

Oh, if the right stick doesn't do it, see if the left one is froo to move side to side. I don't believe there is a detent setting for it though.
