Just got my first tractor and Brush Hog mower. I am not sure how to set it up correctly, how is the "tailwheel" to work? I know it has adjustment for height, but then if you lower the lift too much, the front dips down. Should the deck be level? Also, I noticed that my tailwheel does not spin and track easily with too much weight on it, if I lift the 3pt, it works fine. Do I have something out of adjustment?

When I got it, the guy was using it without a tailwheel, because the bearings were out. I got a new wheel and put it on tonight.

Need help,thanks,
Tim

Adjust the top link so that the rear of the mower is 1" higher than the front. Adjust the tail wheel so that it only lightly touches the ground when mowing on level ground, this will protect the rear of the mower from digging in when you encounter uneven terrain but not have heavy weight on it all the time so as to wear out bushings/bearings. This is the advice given in my owners manual and it works for me.

If you haven't tighted your toplink you may want to start there. When you tighten that the front of the mower should lift up slightly. This will allow the wheel in the back to track properly.

You may also need an overrunning clutch on your pto shaft if you have a trator with out a live pto. ( uses the same clutch as the ground wheels ) This is to keep the spinning mower blades from "pushing " the tractor when you need to stop. and DON'T give anybody tractor rides while you are mowing!! Be careful, bushogs can give you a permanent bad hair day.

Would recommend, as stated below, to replace the toplink with a short section of heavy chain, if you are mowing anything but really smooth terrain. If you don't, you run the risk of bending something when you go into a low area and the mower wants to flex upwards, but can't.

My tailwheel doesn't do too much...just kinda spins when ever it touches the ground.

Tim,

Do not, I repeat, DO NOT replace the top link with a length of chain. That is a prescription for disaster! If while going forward, the front of the mower hooks a stump or other obstruction, the mower can flip up and crush you against the steering wheel. That will not be pleasant for you or for the survivors.
The rigid top link will prevent this from happening.

I can tell ya how mine is on my M.I have the tail wheel removed,same problems youre having,guess its the type of wheel or something.I have collars on my cylinders to keep it at a certain height,adjusted the center link so that the rear of the brush hog is a little higher than the front.Also with the wheel off,I can back into some of the places I keep cut without worrying about knocking it off or bending it.My feild is pretty flat with some hilly terrain but thats no big deal on my place.

I don't lift the tail wheel up when I mow. I let the tail wheel carry the rear weight of the cutter and the lift arms carry the front. I set the rear wheel to the height I want to cut. Then I lift the 3pt so the the front of the deck is about level with or slightly below the rear of the deck. The rear wheel rides along on the ground and turns easily as I turn. It even swivels easily as I backup.
I only lift the rear wheel off the ground if I need to cross over something. Otherwise, it is always on the ground.

If your tractor doesn't have a "hold" position on the hydraulics, you will have to use chains to keep the front of the mower at the right height. Use the tail wheel to set the height that you want to cut. Your top link should have some sort of slack built in. If it doesn't and you go through a ditch you can bend things up.....you can use a chain if the mower doesn't have a built-in slide or pivot mount. Also check to see that the slip clutch is working (if it has one), or if not, that there is a soft "shear" bolt where the pto shaft attaches to the gear box.

I agree with what Nolan said. You're just going to have to dub with it until you find out what works best.
BTW, it's easier to mow smooth, even ground. In NH we don't have any smooth, even ground.

Deck should be level, or nearly so. Some folks prefer to have the nose slightly lower then the tail on the theory that the blade cuts the brush with the leading edge, and never makes contact again, reducing drag.

You adjust deck inclination with the turnbuckle of the center link of the three point lift. Off hand, it sounds like you need to expand that center link on your tractor and brush hog unit.

As you noticed, the tail wheel doesn't pivot well with the hog sitting down right on it. Myself, I hold the unit up with the tractor (since I have an old p.o.s. 8N, I use chains). The wheel hangs out freely back there, catching the ground only to prevent the hog from digging in. It works for me.
