X739 Snowblower attachment stopped lifting

[Gdarbo6844]

I was using my tractor to remove snow whe the snowblower attachment stopped lifting. I can still remove snow but can not lift the snowblower attachment. The chute turns with no problems and the augers work fine; just can’t lift the attachment. Any ideas why it would just stop working?

Disconnect and re-connect your hydraulic hoses.

Did that and still not working.

If you can put it in a warm place or you have a salamander space heater/torpedo heater you should heat the tractor and snowblower for a while to melt any ice buildup under the frame. Hopefully the cylinder is not bent.

I had it in my garage all day yesterday and "thawed it out. Still not working after that. I looked at the cylinder and no siggn of it being bent. Prior to it not working suddenly I did not hit anything hard or unusual.

It still has me stumped as to why.

BTW, when I move the lever for the snowblower, I do not hear any sound as if it was trying to move. I looked at all the links and everything is in place from the lever to the snowblower. The chute still works and that is run by hydraulics as well, although a different line.

Does your X7 have the valve that allows selection of front lift or 3 point hitch? From memory I think this directs flow from one to the other but not 100% positive though.

another thought are you sure the lever is actually moving the spool in the directional control valve?

Can you switch hoses around. I mean hook the lift cylinder hoses to the chute ports to see if it is the cylinder or something else. More than likely the cylinder is fine.

What is a X379 ? Any pictures ?

Not sure I am smart enough to understand the questions you are asking but I will do my best:

On your first question, I believe you are referring with the 3 point hitch, to the ability to attach a mower underneath or for front lift, that is where the snowblower goes. The valve you refer to is under the tractor and you turn it counter-clockwise when you attach the mower and clockwise when you attach the snowblower (front). Yes, I have done that.

On your second question, I do not know how to tell if the lever is moving the spool in the directional control valve. That may be my problem if I understand the purpose of the directional control valve (which I have no idea what it looks like or where that is). How can I tell and how would I fix that?
