Folks,

I am planning on putting a stay chain kit on my 9n brush hog. The tractor is an hour away so I can't easily measure them myself.

Two questions:

How long (usable) are standard top link pins? I need one a bit longer to accomodate the stay chain brackets.

How long (usable)are the standard draw pins? I'm going to need longer to accomodate both the stabilizer bars AND the stay chain brackets.

Thanks much!

Robert

As Dell stated, there are only 2 lengths of your Cat 1 toplink pin (at least that I've found). I got the long one (see it here). Notice the double "adjustable links" (for lack of a better term, that's what I call 'em) that allow me to adjust my chain length.

And
here's how I connected the lower end of my chain to the brush hog...

There's a bunch of different size toplink pins... however I can tell you that my KK 5' rotary mower will hook up behind my NAA with chain brackets made of 3/16 or 1/4 plate, and the stabilizer brackets from tsc, and a standard lynch pin. They will also fit on my 8n, however it is a tight fit, as the stabilizer brackets are old ones.. and beefier than the tsc ones.. I had to grind a chamfer on my lynch pins to get them to start so that I could then whack them in the lift pin holes using whatever handy... rock.. toplink pin.. hammer.. etc. )

So you need to figure out your bracket thickness, and stabilizer bar thickness.. and keep in mind the stabilizer bar will have a slight angle to it, front to back.

One of the lower lift arms that was on my 8n ( now replaced ) had the ball pivot ends ground down real flat.. almost flush with the arm.. My guess was to make a tight fit a tad easier to hookup for a similar situation.

Robert..... ..you are wize to ask questions

The Cat-1 3-point top-link pin under yer buttbuckett comes in only 2 lengths, gitt the longer one. Simple, eh?

I bolted my stay-chains to the brushogg. You're clever enuff to figger out how. The brush-hogg lift pins are too-high and you don't gitta good lift angle.

Stay-chains are great because your chain collapses when you need to lift to clear an obstical, and when you lower yer hogg afterwords, it sets backdown to where you were previously mowing height; all without looking behind you and running into that tree/fencepost/creekbank/rock infront of you..... ....Dell

Dell: Where did you bolt your stay chains on to your bushog? I'd like to do that so I don't run into anything lookin back either. Do you recommend using shorter chains to the lower links or longer chains to the bush hog? I'm running a 52 8N with a 5 ft. cutter. Thanks. GA Jim

Jim..... ...you need to understand how these stay-chains work. They are NOT the anti-sway chains that bolt to your PTO brackett. They are LONG chains (that are adjustable in length) that form the hypotenuse of a triangle described from the 3-point adjustable toplink to the top of the brushhogg and then down the brushhogg 3-point brackett to the lower-linkpins and thens back to the buttbuckett toplink pin. The chain collapses when you hydrauliclly raise the hogg over stumps and rocks and the chainlength (which you've set previously) restricts the hogg from going too low and start mowing ground instead of vegetation. Pretty simple really. The chains also take the weight of the brushhogg off'n yer hydraulic pump too..... ....Dell

Dell: Thanks for 'splainin it. I couldn't figger out how the sway chains could possibly hold up the hog. Are these sold as a kit? Or, should I just make my own. I've got some strong galvanized chain I could use to make one. Thanks again. I git it now. GA Jim

Jim..... ....yes, limiter chains are available as a kit $20 (cheap) they come with notched plates to set your chain lengths. There are also several "how-toos" in the archives. Rosscow is one author, do a search. It ain't worth my time to make my own..... .....Dell
