I started to re-mount my 60" mmm to my BX 2230 this morning. PTO attachment was trouble, but followed advice here and cleaned out coupler and regreased. Made it easier. Went to lower rear links. No go. Tried the procedure for bleeding hydraulics (as stated in manual). No go. Checked to make sure height adjustment knob at "0" (it was). hydraulic lift speed knob wide open (and even tried lowering with that knob at several different positions. Still, hydraulic lifts in rear and at mid-mount both wouldn't budge from top position.
Came in, checked here, saw someone with same issue say he pulls down rear links by hand when attaching mower deck. Tried that. Worked. Before attaching mmm, I raised it again, worked fine, went to lower, wouldn't go. Then I slung a bucket ( with a very heavy logging chain in it) over one of the lift arms in rear, which was in nearly top position. Turned on BX, hit lower knob, rear lift arms and rear links came down quickly.
So, is this the way the rear hydraulic is supposed to work? Or is there something wrong? I mean, does there need to be weight on rear hydraulic for it to come down? Also, I noticed that, with 3-pt hitch in lowest position, if I took weight off, then I could raise lift arms by hand easily. Again, is this normal?
The reason I just noticed this now is that I remembered that the first and second times I mounted the mmm, I had a ballast box attached to the rear lift arms (using it for tool box), so the weight would have brought the rear links down. This time, I had nothing attached to the rear lift arms.
Any thoughts really appreciated. I need to find a good resource that tells me how this stuff works, but haven't been able to find anything other than these forums (which are a great resource).
