I had looked online last year at 12ft batwing cutters by Landpride, Bush Hog, and Rhino. Maybe 1 year or more before that I had actually seen a Rhino. And not until November of last year did I see the Bush Hog 1812. My dad decided he would buy the Bush Hog if I liked it. Since he offered to make the purchase, I did not dispute or discuss the others with him because he was already aware the other brands were also available. Respectfully, I said yes I like it, and I did. Did I like it better than the others? That's hard to say honestly because online specifications and real world operation are 2 completely different things. However out of the 3 mentioned and based solely on internet research, I don't think Bush Hog would have been my first pick. But if that is the one dad wanted, plus we have good dealer support from 2 nearby locations, and the plant is also near then I agreed that I did like it. Besides, I have a 15' and have ran several other 15' as well. So last November my dad purchased the BH 1812 to pull with our Kubota M5040.

Most if not all of the 12ft batwing mowers require only 1 rear SCV, likely trying to accommodate the smaller tractors that often only have 1. It is an option to have it hook to 2 SCV's, so we opted for that which also meant we had to have another SCV installed on our tractor because it only came with one. The Bush Hog is rated for 50-75 PTO horsepower, but the M5040's rated 45 PTO horsepower does just fine with it. One feature I noticed that seemed good about the 1812 was the E-Z clean smooth decks for both the center and wings. I also liked that three gear boxes have a sight glass to verify the oil is at proper level. The 1812 also has a PTO holder that folds up to hold the PTO when it is unhooked from the tractor or simply folds down against the tongue when in use. The Bush Hog also came standard with red and yellow rear lights which I assume operate with the flashers and brake lights. Although I don't ever recall having a wheel bearing cap come off while using any cutter, I notice the BH has a piece of metal that curves out around the cap to protect it and keep from getting knocked off. These are small features, but all seem nice if needed.

So now we have a nice 12ft. cutter to maintain the property, and I want to see that it lasts for many years. I am keeping it very well greased as regular maintenance because I DO NOT want the expense of having to repair those golden$$$ driveline components. My other concern is over years I have seen many cutters with the decks rusted. Some have surface rust while others actually need the deck replaced. So the E-Z clean smooth deck design would definitely help clearing the debris off so it doesn't hold water and cause rust. So with regular maintenance, keeping the oil checked, greasing, and cleaning I think it will definitely serve it's purpose.

Excited with the new purchase, I could hardly wait to take it out and mow (I wish I had that same enthusiasm all the time about mowing). I did not adjust it initially, I left it as the dealer had it. It's first use was mostly light grass and broom straw. Now I am going back a few months and counting on my memory, so do not hold me to this initial evaluation since it may not be nearly as noticeable as I think it was or it may have been the way it was adjusted. But I immediately noticed it left more of a windrow than I expected. It has been adjusted since and honestly I don't recall how it looks now because it may be something I am used to seeing or it may not be as noticeable. I will see next time I use it.

Something I noticed from it's first use that I still notice it does is the amount of clippings it throws on top of the deck. There is a gap between the center section and wing at the very from of the cutter. It's not a gap on top between the decks, but seems like the center deck's front edge is a couple inches farther forward than the adjoining wing's front edge. This gap makes a huge difference. Clippings are constantly thrown out here and end up on the cutter. I also noticed quite a bit of clippings coming up along the wing pivot rods where they attach to the center deck. I don't really think there is much gap here, no more than a 15' if I remember correctly, but it does throw more clippings. How much? Just a guess to give you an idea but if I took the 12ft and cut 8" grass down to 2-1/2 inches over 10 acres, then take my 15' and cut 24" grass down to 3-1/2 inches over 20 acres, the 12ft will accumulate more debris on it's smooth deck than my 15'.

Talking about the debris collection reminded me about the wing locks. The center deck has 2 pieces of steel maybe 2" wide and 4" tall welded near the front and side of the deck. The 2 pieces are spaced about 1" apart. The wing has 1 piece of steel welded to it so that when the wing is completely raised, the 1 piece from the wing will slide down between the 2 pieces of the center deck. All 3 have holes to accommodate the pin which is neatly secured in a nearby hole. That prevents you from having to remove the pin before raising the wings. It's a simple, yet effective design to secure the wings in the up position under ideal conditions. But if you finish mowing and raise the wings completely, then dismount the tractor to go install the pin to lock the wings you will find it doesn't line up. Hmmm, back to the tractor. Lowered the wings completely then raised them all the way up again. Dismounted tractor only to find the same problem. What happens is that the cutter throws so much debris on the decks that enough has managed to get between the 2 vertical wing lock pieces welded to the center deck. Raising the wing, the wing lock welded piece starts between the 2 pieces but will not allow the wing to lift enough due to the amount of debris. And after lifting the wings 2 times before realizing what the problem was, the debris was now tightly packed between the 2 pieces. Tight enough I had to use a screw driver to scrape it out before the wings would lift enough for the lock pin to be inserted.

I also noticed during the first use that the plastic driveline guards spin with the shafts. My 15' and others I have used have a small chain connected to them which keeps them from spinning. Having never seen one where the guards spun with the driveline, I went to the manual thinking the chains were left off, but I found the 1812 doesn't use guard chains so the plastic guards were apparently meant to spin with the driveline.

So after I get finished mowing with the 1812, I decided it was now time to clean the debris. Besides, a rusted deck is one of the last things I want. It went pretty simple as expected, using my lawn blower to clean it. With this being my first new cutter, I was a little particular about keeping it in top shape. That probably also comes from running a cutter for my neighbor that is nothing more than a rattletrap in constant need of repair. Before having our 1812 I used a Bush Hog 84" finish mower. I'm not sure what other people do, but I generally try to wait until the grass is dry before I mow it. Damp grass that gets thrown into the corners under the mower will soon dry, harden, and are usually there to stay until I get the pressure washer to clean it. I was thinking, how can a deck on a new bush hog rust out? The surface is painted, so I wouldn't expect much problem there. But under the cutter is where the paint is quickly gone. It is also where wet grass clipping get stuck. So I think (just my recent thought and could be wrong. I am wrong about 98% of the time anyway) most problems with a deck rusting out must start from the underside, that is assuming the top is kept clean. That was a lot of reasoning for me to simply say I decided to clean the underside of the cutter. The wings are no trouble since they are folded up and it is all easily accessible. My big surprise came when I started to clean under the center section. I know Bush Hog advertises the E-Z clean smooth deck. I made an assumption which turned out was a mistake. I expected the bottom of the deck to be smooth, bracing on top similar to my 15', then a smooth deck on top covering all the bracing. Wrong! All the bracing for the center section is under the deck, and it offers many places for grass and debris to accumulate. So I start crawling around the deck with pressure washer in hand, spraying from every angle trying to clean every corner under the deck. After what seemed like a very long time and still fighting debris and a sore back, I finally heard the greatest sound I could have heard at that moment....the sputter of my pressure washer running out of gas, WHEW! Stand up, stretch, walk a minute, and refuel the pressure washer. Now time for a huge decision. Do I quit in the middle of my cleaning project and consider it "good enough", or return to the torture of bending, squatting, and crawling around cleaning it. Geez, I hate to quit since I have come this far. Geez, I hate worse to think about finishing. So I made an executive decision right then. I disconnected the Bush Hog, pulled the tractor around to the side out of the way, returned with the backhoe and chain. Yes, I chained the tongue of the bush hog to the FEL of the backhoe and raised it up maybe 45 or so degrees. Viola, easy access to the decks underside, so I went back to cleaning. OCD?, maybe. But I got it clean. Picky? yes! Heck, I would rather the deck been built upside down so the bottom was smooth and bracing on top.

Overall, I think the Bush Hog is definitely a well built cutter and will last. But I would expect the other brands to be as well. If I went out to purchase a new 12ft flex-wing today, would I buy the Bush Hog 1812? I doubt it unless I was really disappointed in the others. Just from reviewing them online as far as specifications and not considering users reviews, I would likely lean toward the Rhino.

What is the market for the Bush Hog 1812? I really don't know that there is one. I don't follow the market or anything, so just my opinion, but I think either the 1812 will have to be changed or discontinued. I don't see there being much demand for it.

Happy Cutting!!

Thanks for the read. I bought the LP 15ft last year been very pleased with it. I think the 12ft is a good size we have the straight deck Woods and it is horrible on unlevel ground and moving,the 12ft batwing great idea.

C4Ranch, it was purchased to keep 40 acres mowed maybe 2 or 3 times a year. It has a lot of broom straw, but new tree growth sprouts around 2' tall are common coming from old stumps that were cut flush with the ground many years ago. The tractor doesn't have any trouble with most anything I have been through. In some really thick grass (I always called water grass, but IDK) I generally slow down to make sure I get a good cut anyway even on my big tractor. On a side note, it doesn't seem to take as much PTO power as our 84" rear finish mower but I guess it depends on how low I am cutting and the grass thickness. I really don't have many or steep hills to deal with. The way the land is, it works out that one hill I cut travelling along the hillside. Other hills are generally very short climbs, maybe 25' elevation change at most.

C4, what are you looking to mow and what size tractor? I have a few more thoughts that I did not get into.

Almost forgot! I used it yesterday to mow my yard. I have attached some pictures that I just went outside to take.

That comparison sheet has Bush Hog's obsolete 2212. The new cutter is the 1812. I know the old had 4" blades and the new has 3", plus the 1812 has slower blade tip speed. There may be other differences as well.

Sorry for all the multiple posts, but that's how my thoughts are. :) A few here, and a few there. So I wanted to add a little more.

I reviewed the 4 mowers, but without looking back I don't want to say specifically which one has what but it's something you could look for if it matters to you.

Bush Hog's 1812 has the overall slowest blade tip speed. I say overall because one of the others has a speed very close to BH or possibly even slightly slower in one section, but the other section is approx. 1,000 fps faster.

Bush Hog has 1 leveling rod. At least one of the others has 2 rods.

Bush Hog's minimum cutting height is 2". At least one other cuts down to 1-1/2". 1/2" isn't much, but since I try cutting my lawn with it I think it would make a difference. Even if I cut with any of them at 2", I would think the ones that cut 1-1/2 are less likely to scrape the ground whereas they would be lifted 1/2" and the others would be all the way down.

Also depending on how low you plan to cut, the overall length may matter. I know the Bush Hog is longer than Woods and Woods is longer than Rhino. Not sure about Land Pride. It seems the Bush Hog is about 20"s (???? memory) longer than the Rhino. The longer it is from rear tractor tires to rear cutter tires, the more it will scrape the ground.

Rhino's specs show an upper and lower deck thickness. A smooth bottom would be much easier to clean under than others. There are at least 6 exposed braces if not more under the Bush Hog's center deck. That leaves a lot of corners for debris to collect in.

Bush Hog is the heaviest overall and tongue weight. It has around 50% more tongue weight than the Woods or Rhino.

Bush Hog recommends a minimum of 50 HP. Others require 35 HP, 40 HP, and not sure about the 3rd. This is one reason I asked what you were planning to cut. For the 50 HP Bush Hog recommends for it's 12ft, you could get a Land Pride 15ft that requires the same 50 HP and has about the same (actually less I think) tongue weight of BH1812. The Land Pride's 15ft also has a faster blade tip speed. This is one reason I don't see much market for Bush Hog. If you have 40 HP, that rules it out. If you have 50 HP, you now have the option for a 15' cutter. I don't know how the price would compare, so that could be a determining factor. The 12ft may be a better option if you have tight areas to mow. Or if you haul your tractor and cutter, the 12ft may fit where the 15' may not due to length.

Jumping around again on thoughts, but Bush Hog's wings allow for some movement without affecting the cylinders. Others may as well, I am not sure. We have two SCV's with our wings hooked up separate from the center. I let the wings float anyway. But if you have only one SCV without a float position, the wing will exert hydraulic pressure on the system whenever the terrain causes it to raise. The Bush Hog's design allows for some movement, so some changes in the wing height will not affect anything.

I also notice something in the owner's manual of our 1812 that probably doesn't concern many, me included. But if you wanted to go specifically by the manual, Kubota's 5040, 6040, 7040, 8540, nor the 9540 are recommended. The manual says not to operate the 1812 with any tractor that has less than 60" between the rear tires.

Thanks. I would be cutting native grasses mostly. My fields are not as manicured as yours and I would do it just to keep things under control. Your pics look great!

My tractor is a grand L cabbed with 45hp pto, FEL and HST.

Edit

Also have 3 remotes, 2 with float

According to the Rhino TS12 Brochure downloaded from their website, you can see in the first picture how it has a unique tongue design that allows it to pivot on the cutter itself which improves turning radius.

I believe the Rhino TS12 was the first to come out with the 12' flex-wing cutter.

The specs show the TS12 overall length as 148". I measured my Bush Hog 1812 yesterday with it hooked to the tractor as 180". That's a huge difference! I pay attention to specs and try to figure how most things play into actual operation, but I never thought about the cutter scraping as it went over humps. I can imagine 32" makes quite a difference.

You can see in my picture how the rear wheels extend so far behind the cutter. You also see the slot where the wing cylinder attaches that allows for some free movement of the wing without affecting the cylinder.

Woods advertises an advantage to its rounded front design. I think that is just advertisement and possibly just the opposite of true. If it did not have any drawbacks and was truly an advantage I would think the other manufactures would have caught on by now and implemented a similar design in both the 12' and 15' cutters.

Woods also advertises its easy change blade system using a 3/4" wrench. I have no idea how it is designed but that is a whole lot smaller than the BH blade bolts.

As far as my manicured fields, that is actually my lawn. My fields are cut quite as low.

Finally someone with a 12' BW! Thinks for the write up! I've been casually looking at them

I've got a landpride 2512 and it it's been great so far
