Snowblower chute rotation

[k countryman]

Deflector actuated but chute rotation does not

 

[RCW]

Wow - that's not a lot of information to go by.

Is this an LX3310 tractor? Or an L3310?

What is the model of the 51" snowblower?

How are the deflector and chute rotation powered?

Hydraulic (I assume) or electric (possible)?

If powered by hydraulic, is it through a third function?

Do you have pictures you could share?

 

[GreensvilleJay]

maybe it's a '3rd function' setup not working ??

 

[k countryman]

It is an lx3310 tractor. 2970 51" front blower attachment. Hydraulic with electric toggle switch on lever in cab. Deflector chute is operational but chute rotation does not move by activating toggle. Regardless of toggle position only deflector responds. Have replaced diverter valve on blower. Can disconnect hydraulic lines and move chute by hand, so no hydraulic obstruction. Seems like toggle is bad, but tried connecting a new one and it didn't fix issue. Maybe my Guage wire was too small? I can post pics later. Fuses are all good too. Our dealer has been of little help .

Pop the hoses off the cylinder and see if youvare getting flow. My guess is the diverter is not diverting.....

I have and that is how I know there is no problem with with hydro flow

How can you have flow and no movement?

Plus I replaced the diverter valve at 500.00 and it didn't fix issue

 

[k countryman]

I will try again with hoses off and move lever in cab to see if there is flow from hoses to blower motor.

First of all I was thinking electrical cintrol not mechanical.

Are you using a third function valve?

I looked at the Parts diagram and rotation is by a hydraulic motor. If you are using the bucket spool with a diverter you will get pressure on BOTH hoses and the motor will only rotate in one durection.

need you do some basic electrical trouble shooting
1) confirm you get +12v to toggle switch
2) confirm you get +12v OUT of toggle switch
3) confirm you get +12v to solenoid valves

All this can/should be done without engine running.

BTW is there an inline fuse holder between where the 3rd function gets it's power from the tractor's fuse panel and the 'toggle switch'. Post the wiring diagram if you can

ALSO check for a proper ground for the solenoid valve coils !
And....remove coil connector, measure the resistance of each coil.

Fuses are intact. Know there us hydraulic flow because bucket raises and lowers.

You are making something simple complicated.

Bucket raises and lowers tells you NOTHING about whats happening at the motor.

Take the hoses off the motor and operate the controls to rotate the motor both directions. You should get oil flow from exactly one hose in one direction and the other hose in the other direction.

The snowblower comes with a motor for rotation but a manual deflextor adjustment.

Who added a diverter and hydraulic adjuster for the deflector?

Did the rotation work before the diverter was added?

hmm... Hydraulic with electric toggle switch on lever in cab.

A few pictures will help !!! Especially the wiring !!!!

Sure sounds like someone 'bodged' a 'diverter' setup on this machine. I'd expect push buttons on joystick not toggle switch on dash ??

He has a hydraulic motor and cylinder on the snowblower. How dobypu control both actuators?

That sounds like the diverter has been added to a third function or possibly one of the spools on the loader valve. I would like to see that plumbing before even thinking about the wiring....

Dan will try that after we stop blowing snow and it thaws out

Toggle switch in cab plugs into diverter part and does rotation and deflection on chute. No matter toggle position, it only activates chute deflection. Toggle is a single pole on/off. This has worked until now it doesnt.

Ok - starting to get this sorted out. If both were working before and now just deflection works sounds like the diverter is dead. Pull the hoses off the motor and check for flow there. Dollars to donuts there isnt any.
