3 pt Snow Blower

Its getting to be that time of year. Considering the SB1174 3 pt rear blower for my 3520. Anybody running the rear blower that can comment on its performance?

I envision keeping my plow on the front and replacing the balast box with the SB1174 - would prefer the rotating hyd chute. Not sure how the hyd hook up would go. I believe I have a 3rd remote valve which lifts/lowers the MMM. Is that what would actuate the rotating chute on the blower?

Also, how do you handle the height setting of the blower with the 3 pt control lever - is there a way to allow the 3 pt to float and adjust to terrain or do you set it down till the skid shoes on the blower contact the ground?

Sorry for all the questions but I am curious.

Thanks

:thumbup1gif::thumbup1gif: Yup, Just let the blower float on the skids.

That's what we are here for, each other to learn. :empathy3:

The chute rotation would be done with your 3rd SCV, the same lever you use for the MMM. As Randy wrote, the blower just slides on the skids to follow the terrain.

Kenny/Randy - thanks. Does the hyd chute control on the blower have something to restrict hyd fluid flow to allow semi precise control of the chute rotation so its does not slam into the end stops due to excessive hyd pressure?

Flow control

Yeah, what you are looking for is number 19 in the diagram (Oriface #M145979). It actually controls the flow and not the pressure to do just what you are asking.

Randy,

Thanks for the thumbnail and explaination. I understand now.
Or you can loose the fixed orifice's, and add your own adjustable one so you can fine tune the speed to your liking. Like this: http://www.surpluscenter.com/item.asp?item=9-7961-4&catname=hydraulic

As Randy wrote, these control "flow" not "pressure", there is no easy/cheap way to reduce the pressure, and you wouldn't want to anyway.

Gus, that is a great idea, it looks like a solid way to rotate the chute.

Gus, where did you get the motor? Is it a certain size, brand, or part #? You have a great idea.
