Rear blade chatter when moving snow/slush?

[aa777888]

Running an iMatch setup, not that that matters. I just like to be efficient I might adjust the top link to find the right angle, but then it's going back to where it was and spacers will be cut to match that.

And not just "No", but "Hell, no" on plowing backwards!!!

Good idea, Tom, except that the upper link works perfectly for all my other attachments as is, so I'd rather not adjust it, i.e. I'd rather carry any adjustments on the implement itself, if possible.

Noise is fine, chatter is not. Perhaps I should have said the thing was frankly hopping, which it was.

Buy a second top link just for the blade - adjust it, and leave it hanging on the blade when you use other implements.

You wouldn't be plowing/driving backwards, you can just turn the blade 180 degrees (assuming it will swing completely around - most do). That switches the blade angle from leaning back to leaning forward. Much less aggressive. Keep the quick hitch, they're great - I love mine too.

Hydraulic top link would be very handy.

Cool idea! I've got no circuit for it, though. However I've been wanting an extra rear circuit for a while, now. Maybe two circuits. Ok, that's going on the project list for next year!

Adjusting the top link should not be a big thing. I have several 3-point implements and make multiple adjustment on each one. There is no such thing as one set point on my top link.

Your rear blade chatters because it's light. A heavier blade would eliminate most of the chatter. Shorten the top link and get the rear blade to tip forward at the top. That should help.

I will sell you my brand new unused pneumatic casters and drilled angle iron with
all the mounting holes that I was going to mount on my 10 year old JD snow blower
but did not because it went to the scrapper.

Agree with others. Combination of light blade and a hard surface = chatter.

Alot of people quickly suggesting changing the toplink to change the attack angle of the blade, and that would be good but ONLY if you leave the blade straight.

IF you ever angle the blade to move material left or right.....there is only ONE length of the toplink that will work. And that is when your rear pivot pin is a perfect vertical. If you angle the blade and it remains flat/even with the ground then the toplink is set right. IF when angled the front edge contacts the ground before the rear, the toplink is too SHORT. And vice versa if its too long.

But.....if you are plowing with the blade straight only, try angling it some. Angled is alot less likely to chatter.

Not familiar with i-match.....but general quick hitches have alot of slop. If there is any slop in the i-match....shims/washers/bushings. Tighten it up because that adds to chatter

Then it comes down to adjusting the lift arm height to level the angled blade side to side

I need to adjust the top link often, the different 3 pt attachments are, well, different... You may get less chatter if you turn the blade backwards.

On gravel or early in the season, most of my rear blade plowing is done with the blade "reversed".
