Western 6'6" unimount plow flopping forward...

    I have a 6'6" unimount plow on my 93 S10 Blazer. Occasionally lately when plowing through the thicker snow, the top of the blade is going forward while the bottom is being plowed under and back. So, it flops forward under workload. I notice the cutting edge along the bottom is deteriorated and probably much narrower than it used to be. It is about 2 inches on one side and a few more on the other. So, it looks as if the plow blade (at sitting state) is leaning forward a little. The top appears an inch or two in front of the bottom of the blade. Is this the difference due to the cutting edge being worn? Also there are 2 large springs for adjustment behind the blade. Do these compensate for that or is it just in need of a new cutting edge to be proper?

    Appreciate your tips.

    What you are describing is called "Tripping". The spring you referred to are the trip springs and yes they are there to control the amount of force required to "trip" the blade. It could be the springs need to be adjusted or replaced. The blade is designed to trip when you strike an object to prevent damage to the plow. Hope that helps.

    Springs do wear out. Cutting edges never wear evenly. You could have hit something hard enough that bent the plow. Best thing is to take a picture and post it for us.

    Thanks for the replies...

    I don't have a working digital to show a pic with. I'll just adjust the springs there and see if it helps. I'm sure it doesn't help that the cutting edge is almost worn away. She has alot of mileage on it from the looks, but I must say it does work good so far.

    Appreciate for your input.

    I adjusted the springs on mine. Spring tension should be adjusted so a standard piece of paper pulls hard through the spring.
