Hi
I am finally plowing some snow here in the Northeast. The 2320 with the 54" blade does a great job, although a bigger plow would be good. I have been hearing a "Rattling, Vibrating," noise underneath when I first start the 2320. It is not the hood latch, I dampened that with electrical tape. Also I am not talking about the engine itself being noisy from the cold when it first fires. Has anyone a clue?

Thanks

VP

Lot's of things can rattle or buzz

Hiya,

I would look to the foot brake linkage or maybe the exhaust pipe mounting.

When Diesel engines start, they run rough because the air does not heat as well from the compression stroke as when it's at operating temps so the fuel does not burn as well. (this is why they tend to smoke and smell like a candle) Since it's running rough, any pivoting linkage or sheet metal components can vibrate enough to make noise. (Ask your mechanic how much noise a loose converter heat shield can make on a car)

Total WAG as I haven't been there in person,

Tom

Hey VP
Hard to tell what it might be.
When it first fires up,you need to "get under there" and try to pinpoint it,or have you tried that.

You don't have any MMM linkage under there do you?

could it be coming from the plow?

i notice that on the 455 the skidshoes rattle when it is at low idle. it could also be maybe something in the operator manual tube.

also sometimes the 3pt. height control handle hits up against the stopper and can really make an annoying rattle

No I dont, not yet.

I think you probably do. The MMM adjustment knob and the underside linkage is probably there. Turn the MMM knob so the linkage on the underside is all the way up. Worth a try.
