Snow JD 3520 temporarily loses power while blowing snow

Will check those things once I get the hood unfrozen.
With all the snow on it and the very cold weather we have been experiencing,
couldn't get the hood open last night. Thanks for the input

I have the same problem with mine snowblowing or operating in blowing snow. I only notice it as night as my work lights will get dimmer and dimmer and then all of a sudden get bright. I assumed it was the alternator icing up, not too worried about it as long as it doesn't stop charging for too long.

Have you had any discussion with John Deere about it?

My M7040 Kubota experiences dimming lights etc when show blows over the engine. It is just the belt slipping for a few seconds.
Dont worry about it just try and blow the snow from a direction that does not have a cloud of snow pass over the tractor from the blower discharge.

Thanks Dave. I'm convinced it is something as simple as that too.

I have a 3320 with the same issue and what I determined was that snow was getting on to the Alt belt causing it to slip. I tightened the belt and the problem went away. I go through this about once a winter where I need to re-tighten the belt. I have yet to come up with a permanent solution.

I blew snow twice over the weekend and both times was very diligent about not having snow blow back over the tractor. Never had the issue occur.
I did check the tension of the alternator belt and it seemed pretty tight. I still might cover the grills to prevent the snow dust from entering. There seems to be
enough clearance that air movement won't be an issue in the winter months.

What I have found with my tractor is that the belt needs to be very tight-I put a bar between the alt and the engine block and put enough tension on the belt so that it is very difficult to deflect the belt more than 1/2 inch along the longest distance between pulleys. I should also point out that my tractor has a V belt-if JD has switched to the micro v belt with spring loaded belt tensioner this problem would likely go away.

I have the same problem of slippage from the rubber wheel basic transmission setup on walk behind snowblowers.

When it is happening try easing up the electrical load. Shut off the heater and the lights and see if it helps. May just be the strain on the charging system.
