Bush hog rookie needs help

I have recently acquired a bush hog. I don't know how to set it up for the tractor. Should the weight of the bush hog be destributed between the side skids, rear wheel, and 3 pt hitch?

My ground is pretty rough, when I tried it with weight on the skids it ran pretty smooth, but I kept hitting rocks and trash in the paddock. I then lowered the rear wheel (raising the cutting deck) and raised the 3 pt a bit. Hardly any weight on the skids, blade nice and high. Didn't cut up any rocks or trash, but boy did the bush hog shake and shudder.

What am I doing wrong? I'm assuming that some weight should be on rear wheel. Should 3 pt keep front part of skids off ground, all weight on skids or some weight on front skids?

I'm sure that someone has some answers, and I'd really appreciate hearing them.

Thanks

I don't know, I guess I grew up in a different time.....I know that it is to the operator's advantage to NOT have an over-running clutch... Ofcourse, we didn't have such a thing, then as a over-running clutch ( except on the old JD Baler) and it was built into it at the factory... I always Hated that clutch....if an animal, or ( God Forbid ) a person feeding the pick-up got caught in the pick-up....you had to watch it go completely thru the equipment, before it stopped.. Without it...I can hit the clutch, and Jamb on the brakes and STOP the Mower in about 1 second... Now..which sounds safer, to YOU..???

I added a loose link to my top link so I have weight on my tail wheel most of the time, makes it float along and follow the ground.

A person's reaction time is over a half a second, likely a machine with a flywheel will take several seconds, not one, to stop. At 540 rpm, 4 seconds time is nine revolutions per second, or 36 revolutions if your reaction time & brakes are EXCEPTIONAL.

Do you really think that will help anyone?

You ever trist one into, stopping a piece of equipment, I guarantee it WAS an Emergency.....better that than the other....!! I never broke a PTO, or a shaft stopping them this way, and been doing it for nearly 50 yrs... Besides, You Do use a friction clutch on the PTO shaft, right.?? That takes the shock out of the driveline,assuming you break it loose, every year...!!

To each his own, but i run mine with the draft adjusted just below where it picks up the mower. It is not such a strain on the engine when you get in tough saplings and tuff heavy grass. Sometimes on a large sapling, you can pull over it , raise the mower, ease onto it and gradually lower it while stopped over it.

Buy some no. 3 grade shear bolts and keep them in the tool box along with wrenches. Turn off the tractor while replacing the bolts. Keep the pto shields in place and keep the u-joints greased.

keep children and pets clear of where you are cutting. Debris flies out probably close to 100 miles an hour. Look before backing. Where safety googles- debris flies forward from under the mower and can glance off the tractor wheels or fram and hit you. be careful!

Here's a copy of an old post from a first time bushhogger:

The weekend is but a memory. The scrapes and cuts are healing, though I still look like I tried to have s(ex) with an angry blender. And I'm getting to where I can walk without those stiff muscle jerks and grunts.

I never bushhoged before in my life, and you all didn't warn me enough about it! Shesh. I had a raspberry cane come whipping across my face slicing my eyelid. I had a tree manage to jam not only my brakes but my clutch as well. And that was in the first few minutes. Then things got really entertaining.

The bruises on my legs and back where the hog would occassionally throw things at
me are turning a very pretty yellow.

It's truly exciting when you enter into that big rose bush only to have it wrap itself around the pto shaft and beat you senseless with it's thorny carcass.

Or that tree that tied itself around the tractor's wheel and clunked me on the skull with it's root ball instead of going into the hog where it could be thrown at me in smaller pieces.

And lets not forget that exciting feeling as you turn on the slope only to have the hog catch on something and try to pull the tractor over on its side.

I survived. The place looks *much* better. We're ready for the orchard plants to arrive. And I sure did learn a whole lot!

I'm a pretty wild fella in many peoples opinion. But even I will have to suggest to novices of bush hogging, take it easy! The job's a whole lot hairier then I imagined.

The front of the rotary cutter should be a little lower than the back. The 3-point hitch should set the height and you can use a position control. Also attach stabilizer bars; they are inexpensive.USE AN OVER-RUNNING CLUTCH ON THE PTO IF IT IS NOT INDEPENDENT. Finally, excessive vibration could be worn, unevenly balanced blades. Hitting a lot of rocks will wreck the blades. Rather than try to balance them, buy new ones. Good luck and be careful. (Use chain guards if they are available.)

TJ,
You really don't want to run the mower with the sides dragging the ground, one thing is you will get the blades too close to the ground and every little bump, etc., you come across you will bog it down. I run mine with the sides about 2" off the ground. I have not yet got my tailwheel to turn with the mower like its supposed too. I think I have it too high as if I remember right it didn't do it when I first bought it and I adjusted it. I don't mow much with it so I have not messed with it much to adjust. Its a trial and error process of getting it set up but you do want to run it with the sides off the ground and the deck as level as possible. Same thing as the others said about the blades needing to be balanced and all.

like the others said, a bushhog will shake and especially with a compact tractor because of momentum of the cutter. also when you hook up the bush hog, raise it up off the ground and try to move it side ways. if you have any side movement, then adjust your link chains evenly on both sides where there is no side play. that should eliminate some of your shake.i always adjust the front of the cutter to where the skid shoes are about 2 inches off the ground so it will not dig in the ground if you turn sharply. by letting the back of the cutter be lower than the front will also help in cutting down on the shaking problem, but hitting heavy objects and small saplings and assorted junk can also make it shake. the blades are made to swing freely 360 deg in case something is hit and that make for some shake and rattle. be safe and never get off the tractor when the bushhog is running. that is a disaster waiting to happen. always block up the bushhog when you have to get underneath and it is best to have a standby helper also. sorry for all my rambling on.be safe!

There is no "standard" setup for a 'hog, it varies depending on the terrain and the material being cut.

That being said, I usually run with the weight on the tailwheel, and the front of the hog off the ground about 3" or so, terrain permitting. I drive with one hand on the three-point lever, so I can lift the hog to jump rocks or other things I don't want the blades to hit.

If you're in thick brush or saplings, the hog is gonna shake, rattle and roll, that's normal. In fact, it's normal in anything other than light grass and weeds.

If the machine is shaking and banging when you lift it so it's not cutting anything, then something is out of balance, or a blade has folded back, or the gearbox bearings are shot. The most likely thing is that the blades need to be weight-matched. Also, make sure the pivot pins where the blades attach to the T bar are free so the blades swing properly.

TJ:

You need to get the operator's manual...smartest thing I ever did.

If you can't find the exact right one for your hog, Wallace Auto Parts has several on their website for free download. If you read the one that is closest to your machine, I think you'll find it helpful.

Next, even with the book, I think adjustment depends on your land. I adjust mine slightly different depending on which field I'm mowing (I have several with some severe hills that I can only mow semi-safely one way).

Also, don't know what kind of tractor you have butif it is an older one like mine you need an overrunning clutch (ORC)...makes like easier and safer.

good luck!
Tom

This is coming from a novice but I am learning a lot from the great site. I too had a similar problem with my bush hog and discovered that two of the four bolts that secure the gearbox to the deck were loose and/or slightly bent. I replaced all four and have very little vibration. Just my $ .02

any rotary mower,be it a lawnmower or cutter must be slightly lower at front of mower where leading blade tip is cutting.otherwise you will be cutting the same thing multiple times and will require more energy,fuel,horsepower,etc because you are cutting the same thing again and again.
