Ford Back blade

Picked up this back blade this morning. Got it for a decent price. Before I dig out the books, do I need 3/4" 3 point pins or 7/8"? No time to play
today. It's a 787 HD series according to the tag. 8ft. Will be used for moving snow and light work on the food plots leveling and such.
Will pretty it up in the Spring. Merry Christmas to all!
 
Ok. Here's the picture.....

The size of the hole in the crossbar and the hitch category of your tractor will be your answers.
 

Just looking at the photo, I'd say not smaller than 7/8. That may even be a Cat II frame which would be 1-1/8.
 
Lower lift arm width, lower pin diameter, and Horsepower.
(Cat 0- 20", pin dia 5/8", max hp 20)
(Cat 1- 26", pin dia 7/8", max hp 45)
(Cat 2- 32", pin dia 1.1/8", 40 - 100 hp)
(Cat 3- 38", pin dia 1.7/16", 80 - 225hp)
(Cat 4- 46", pin dia 2", 135 - 300hp)
 
What model of tractor will you use it on? An 8' blade is too long to be able to turn it around 180? for back blading as it will hit the tires. On an N-Series tractor, 6 feet is about all that'll work unless you set it up pulling or pushing before hitching it up. It is a good idea to use stabilizer bars too with a back blade. I've found them to be very helpful but they are not mandatory. They help assist in keeping the blade tracking straight and from kicking off to one side, especially when back pushing a load of snow.

Just ordered a new top link for it as well off of Amazon. Local Farm and Fleet has discontinued carrying them. Go figure. The one I ordered adjusts from 24" - 33".
 
You just answered the question yourself!
You need cat 1 pins (7/8") cat 2 will not fit the balls in the lift arms on your tractor!

Looked up your pins on the New Holland parts on line catalog.
Pins are no longer serviced, but they are 7/8" diameter, and the length can be determined by measuring across the ears.
You may be able to get those pins from Land Pride also.
 
I also use a ford 8' blade and it will cover the wheel tracks on your 961 quite well. Mine is not as HD as yours and the rotating top might even come in handy for a trenching or swales to divert water. You also have the holes in the angle to add snow skids if you want to keep the blade up off the ground. Looks like a good one and I'm sure you will get many years of use out of it.

I have a blade like Kirk NJ but I don't quite understand how that one you have works. How do you angle it and turn it around for pushing? It looks like you can tip it side to side for crowning. The picture has me cornfused.
 
Flembo, I have the same blade as the 1st one pictured, only in a newer version. The "turntable" is under the arched part at the rear, and a pin drops down through at the very rear. If you look close, you will see a hole for the pin on the flat at the very end to the left, and the pin in a hole on the right. The pin has a flat strap on the top, instead of a head. You can just barely make it out, if you look real close. The turntable is obscured, in the picture, by the flanges it rides on.

The head gear has 3 ears on each end. The ears are drilled to take a 7/8" pin that goes through all 3 ears. Placing the tractor's lift arms between the inner and middle ears on the head gear gives proper spacing for Cat 1, and between the outer and middle ears gives Cat 2 spacing using the same pins with the Cat 1 to Cat 2 bushings.
