So, removed scraper from 8N and attached brush hog as it needed to be moved from the spot we unloaded it. I have posted some pictures in the implements section and would like to know if I have the thing connected to the tractor properly? It lifted up and down fine and seemed to be ok - but need expert confirmation before I set off into the undergrowth.

I have a feeling that once I connect the new orc to the pto the drive shaft is going to be too long - it looks like it is close to being pushed back as far as it will go and even without the orc it looks like it is too long. Do I need to cut a length off that shaft?

Finally, what gear do you normally use for a brush hog and do I need to keep the rpms up high?

Thank you,

Lee

I have a grass called "Blue-stem" on my place and it's pretty difficult to cut cleanly, but I am able to use 2nd gear until it's about 14" high, then I have to shift down to 1st.

GB, what is that wheel you have on your top link. An adjustment wheel? I've never seen anything like that. Looks like it would make the adjustment of the toplink very easy. If that's what it is, where did you get it?

Kenster;
That's not my tractor. I just posted the pic. for the guy that started this thred.

I've seen those before, but.... I don't know where they get that particular top link. Looks factory though.

Yep, thats the one I was talking about - dont know where that came from - it was on the tractor when I got it going - it is useful as with this brush hog all I needed to do was twirl the handle to adjust the right length - it has a bar to lock it into position too.

Thanks for all your advice - I would like to sharpen the blades - do they come off pretty easily?

You should trim both shafts of the PTO
coupler to allow about 1/2 inch of play
when the hog is in the up position.
This should allow the blades to turn without binding the PTO in any level.

Next you have to position limiter chains
so that the hog deck is at the appropriate
lowest level with the lift control all
the way down. This way you always know that your hog is never going to go below some
minimum.
Adjust the trailing wheel so the the minimum
height keeps the deck level.

In the event you get into bad grass, roots,
rocks you can immediately lift the deck
to cross over and drop it down after crossing.

On heavy grass you need 1st gear.
Light stuff may allow 2nd gear (watch
the turn speed). This assumes a 4 or 5 ft hog.
A six foot hog may be too much for the
machine.

Before you start use a grinder to put a
nice edge on the blades.

Never get off the tractor with the blades
turning.

Make sure there is enough grease in the
hog gear box.

Since your new at this, the blades on a rotary cutter are not always in the cutting position when you engage the pto and you"ll hear a loud bang and the cutter will jump as the shaft tuns the out of balance blade carrier and the centifugal force rotates the blades to the running position. This is normal, but scary to a newbie.
Make sure you check the area you are going to cut. You"d be surprised at the old tires, plows, old fence wire, downed posts, chunks of concrete, etc that are out there. If you hit one of them with your cutter, who ever does your laundry won"t be too happy.

You can always rech under the mower before you hook it up and extend the arms out from the stump jumper so they will be more in bllance right when it starts.

it's also good to check that on a new piece of equipment to make sure the arms are not rusted up... they need to be able to freely pivot on those bolts.

And while you are reaching under, rescue any kittens, skunks, snakes that might have taken up residence there! :)

That's just part of what makes farming fun.. running into unexpected critters and everybody getting a good surprise.

That increased heart rate is almost like exercise!

My sinus surgery took all the fun out of it for the skunks though..... I can't smell a darn thing anymore.
But when I come in the house, the wife knows what I met up with!

Permanent! As you can imagine, there are many things about this that are bad, all the way from great smells of food, etc. to safety (gas, fumes, leaks, smoke, etc). The doc just scraped a little too much & got the sensory nerves. I later told him that I'm glad he stopped when he did or else he'd have gotten my brain!

Ditto wht the others said. DO trime equal parts off each shaft.. IE.. if you need to trim 6".. then trim 3" from each metal shaft and the plastic sheath. The do a lift test and make sure the shaft does not bind at full lift.

Make sure you grease the ORC before each day's use.

Once connected start the tractor (in neutral), engage the PTO and let the clutch up slowly to start the blades to turning. When you push down on the clutch pedal, the blades and the PTO shaft should keep spinning. That means the ORC is working. Without an ORC the centrifugal force of the spinning blades would keep pushing the tractor forward and possible into a fence or ditch.

Go at whatever speed is safe for the terrain your covering. I usally run in 1st gear on bad terrain, or, 2nd gear with the Sherman Transmission in low. In sparse short weeds and flat terrain, I've been known to hit it in 3rd gear.

You may have to cut off some of the PTO shaft. I thought the same thing beforehand but it went on fine as is.

NEVER NEVER go to the back of the tractor if the blades are still spinning. Take your time, don't get in a hurry, and everything will be safe. And WATCH THE SLOPES!

How much of a slope? Is it ok to go straight up/down or across the slope?

Is there just a risk of the weight of the brush hog pushing you one way or another? Either way I will take it easy as it sure seems a pretty barbaric bit of equipment!!!

You can trim equal amounts off both ends of the shaft to make it fit right, and keep the tractor in first, with rpm's at about 1500 to work the hog.
