I've noticed this year on my 430 with my 50" single stage blower the tractor has to go very slow when taking on the full width of the blower in snow. This is in various snow conditions light and fluffy or heavy and wet. Last year I thought it didn't struggle at all taking on any type of snow at full width, or maybe my memory isn't as good as it used to! It's very easy to take on too much snow and have the engine die. When it does start to struggle the rpms drop and there is black smoke. I'm using low gear on the 2 speed transaxle as I was last year. It will still throw the snow okay as long as I go extremely slow or take on half width. I have replaced all filters and fluids on this tractor except for the fuel filter. I have a new fuel filter to install, but this doesn't make sense to me that the fuel filter being plugged would cause black smoke. Any thoughts appreciated.

Tom, I'm not a diesel guru and know very little about them. To me black smoke means a rich mixture...either too much fuel or not enough air... and I agree with you that a plugged filter would not cause this.

WHEN did you change the air filter(s)? Is it possible you've got a nest in there restricting air flow?

My other thought be be something governor related...engine slows down due to a load and governor overcompensates and supplies too much fuel. All I've got! Bob

Check your air filter and the inlet

Sounds like it might be iced up and lack of air will make it smoke a lot

Black Smoke is usually un burnt fuel with a diesel

I will check air filter again. Tractor is stored in my heated shop so its never out in the cold long. It also seemed this way this summer when I had a loader on it moving dirt, the engine would die taking on a full 48" of dirt at a high speed in low gear with ags and 500 lbs on the rear. Heard to tell but it sounds like the engine RPM drops slightly once it gets good and heat soaked, so maybe it is something with the governor?

The other thing to check is that the tube from the air cleaner to the engine is not collapsing and choking off the intake. This one is hard to find unless you happen to eyeball it occurring so if you suspect this cause, remove the tube temporarily and give it another run on the blower. A few minutes in the snow won't hurt the engine

Anyone else with a 430 can you take on the full width of snow with the 50 blower doing anything more then as slow as possible with the trans in low and hydro lever just off neutral?

The air intake tube could be collapsing there is not spring in it, I'll check that tonight.

Keep us posted on how you make out. Mine does the same as the OP's. I've always been surprised by the lack of power when blowing snow. I would have expected more. I'll be following along.

Can't check today - it's fifty, raining, and not a skerrick of snow anywhere. Quite bizarre for the middle of winter.
That said, hitting a heavy bank of snow with the 47" does take a bit of hp to blow__PRESENT

Im in the opposite boat, its -22 f here right now and I don't wanna even pull it out of the garage. I will try to update when I do test it. I did look at the hose in the garage and at 60f it takes a small amount of force to collapse it, we may be onto something.

I did get a chance to use it with the storm we got last weekend in MN. I did get the tire chains on it so I can go much slower, It has no problem going very slow now. I did watch the air intake hose to see if it was collapsing when I went faster, the hose did not collapse and the. I didn't get a chance to remove the air filter and try it again. I will try that this week since it is finally warming above 0F.
