Hi, I've just bought a wheelhouse 523dxi which came with a bunch of attachments, most of which I got working. The hydraulic rotary broom however remains a puzzle. It seems that in order to power it, an additional hydraulic pump was installed under the tractor. It keeps the hydraulics flowing though a reservoir which ist mounted at the left side and can be connected to the broom (see images). Neither of the attachments has any label on it and I couldn't find any documentation. I don't understand how to integrate the the pump into the belt setup, no configuration seems to make sense. Currently the belt is touching and damaging the hydraulic hose when I use the mowing deck, so I can't use the tractor at all. Has anybody seen this configuration and can give me a hint? Thank you!
