I have a BX2230 and a 4' KingKutter XB rotary cutter. Prior to this past weekend, all I had used the cutter for was mowing pastures. Just grass, no stress on the cutter at all.

This weekend, I decided to use the cutter for what I had actually bought it for, mowing in our woods. Absolutely virgin, or nearly virgin woods. Many thorn saplings and lots of tall grass. I was mowing with the FEL riding very low. It did manage to find several, fairly large, branches and similar stuff that you would expect to find.

There is a pile of dirt back there that was probably dumped years ago. Whatever kind of dirt it is, the weeds love it. Some of them must be 10 feet tall. I tried backing the mower up the dirt pile and somehow managed to pull one of the solid tailwheels off of the wheel. So I spent the rest of the day mowing with only one tailwheel. One of our tire guys was able to get the tire back on the wheel, no easy task, but saved me like $47.

During one of my backing experiences, I must have contacted something fairly solid, as I caved in the back of the cutter. Nothing really serious, but enough that part of the back panel drags the ground below the tailwheels. Last night, I turned the mower over and tried to beat this panel into submission with a 5 pound sledge. Although it is better, it still ain't quite right. I might have to buy a heavier sledge and try again.

Anyway, my cutter now has the character of battle scars. I will either need to be more careful or consider buying a heavier mower.

I have yet to see a brushhog that was used for land clearing/brush mowing that isn't full of lumps, bumps dents and bends. Wait till you get a softball sized rock up and dancing around under the deck:) We have an old JD cutter here where I work that looks like a mushroom. you can hardly tell it had straight lines where the top deck met the side walls. As for backing it into the brush, I know it is sometimes necessary, but I try and avoid it whenever possible as the 3PH structure just wasn't designed for pushing. I have bent the mower mounting structure where the lift pins attach doing this as well and mine is a single strap similar to the pictures I have seen of the XB cutter. When busting brush, I much prefer to find stumps and boulders with the FEL as you described. but sometimes the terrain makes it impractical or unsafe to lead with the tractor. Good Luck.

I gotta agree with ron... The most cutter repairs we get here at work come from 'backing into the weeds' where the operator then usually finds a stump or big rock.. and then things get worse..
If the metal is 1/4 or less.. I've had luck with a big beat up pipe wrench and a pipe, adjust the wrench down to just slip over the bent lip.. then apply pipe.. Heat helps... Then you can sand and prime / paint to prevent rust..e tc..

I bought a used JD LX6. I've had it about a year and it runs great. I primarily use it for what it is spec'd for (1" or less) but it knocks down 2" soft woods easily.

I bought it used, without really knowing much about mowers. And it looks good with good paint and I bought it from a reputable and trusted JD dealer. But, the rear of the mower deck has a raised arc that coincides with the blade tip. It makes a raised 180 degree semi-circle on the rear of the deck with a few smaller arcs on the front of the deck. I cannot imagine how this was done. The blades do not flex enough (by hand anyway) to contact the underside of the mower deck. So who knows.

I got it for less than a new KK or comparable mower and it works well, so I just don't worry about it. But I still wonder what the previous owner did to it and how it might have affected the gear box, seals, etc.

Could have bene old blades and loose bolts, and was corrected before sale... could have been a loose blade carrier.. etc.

I hope that's all it was. It just seems odd because this thing looked pretty new other than those areas. All the warning stickers in place. Almost no rust anywhere. You just never know what has happened to used stuff before you got it. But, when I was buying it, the dealer saw me looking at those marks and knocked $50 off the price.

I've got a mark like that on one of my mowers. It was caused by a rock I picked up that made a few trips around. I suspect seals and gears are fine if their is no leaks and it runs fine.

I've got a neighbor/friend who has hit so many rocks with his brush hog that last year when I was building a rock retaining wall and needed some rocks split to fit some tight spots, I jokingly ask if he'd mind giving me a hand.

All fun aside, isn't this why most of us use a brush hog for the rough cutting, just in case, and so we don't ruin those $40+ RFM blades?
