New BX23 HST problem?

[Henro]

I could not get this question out of my mind, and decided to post a specific question in the Owning/operating forum Here to get input from other brand owners as well.

I think I now understand what is happening, at least in my case...I probably stall out when digging into a dirt pile NOT because of the HST circuit, but rather because I am using the second pump on my tractor to lift the loader/curl the bucket at the same time as I am moving forward.

The engine does not have the torque to overcome the load the loader is putting on it through the second pump. The HST pump is popping the PRV at that time too, but either the loader associated PRV also pops, or the engine stalls.

Just a guess, but it sure seems like this is the probable reason for what I am seeing... /forums/images/graemlins/smile.gif
