3-Point Hitch Rear blade implement with 2 holes for Top Link

[hoguester]

I recently bought a used rear blade for moving snow. The blade has two holes for attaching the top link. I'm just curious as to which I should use? Pros and cons of each? Is the top one for Cat 2 and the bottom for Cat 1? Are they for different types of quick attach mounts? Thanks.

I assume it's what you thought... Cat1 and Cat2. One is larger, right?

On modern implements, there is usually a hole at 18 inches to match standard 3 point top link height dimensions. The lower hole at 15 inches is to meet quick hitch specifications.

Don't ask me why they are different.

That's common on cat 1 implements. The lower hole is 15" center to center from the bottom pins which is what is used as the standard for Quick Hitches. I believe the other is 18" on center.

The top link should be pinned parallel to the lower links. This lifts the tool level with whatever pitch you are using it at.

Most tractors also have multiple pin holes. These add more adjustment toward the level I was talking about. They also change sensitivity of top link draft control if your tractor is so equipped.

Thanks all. Appreciate the knowledge!

If you put the top link in the top hole, the implement is tending to lift higher at the rear when three point hitch is lifted up.
