176 (6', commercial, chains, 2000 bucks)
SE8A (8' commercial, 5000 bucks)

I wasn't as up to date on model designations for Rhino as with other brands. After spending a little more time researching them, I'm up to speed on what's what with them. (I'm shopping for a couple HEAVY duty 6' mowers myself)

176? I see a 172 listed in their product line. It's a 72" ECONOMY grade, light to medium duty cutter.

SE8A. Double spindle, medium duty economy level 8' cutter.

Neither are recommended as commercial level mowers by Servis-Rhino. Both are targeting "home-owner, hobby rancher, occasional user" markets.

Next level "up" from 172 series, the 272, is comparable to Bush Hog 296 or Woods BB720. (medium duty) I'm shopping for CY72 or GR72 models. (heavy duty or EXTREME heavy duty) I'm leaning towards the CY72 at this point. I'm comparing Rhino and Bush Hog only at this stage.

BUT... it looks like the tailwheels are of simular design, albiet lighter weight material as their heavy duty and extreme heavy duty lines. These 2 models are anywhere from 500 to 1000 lighter than their extreme duty counterparts. While a great deal of that weight is in places like the decks, the gearboxes, and the hitch, a sizable portion of weight reduction is obviously in the tailwheel assemblies. That said, I still don't see even a light duty mower having a chronic problem with tailwheels bending from normal use. The Rhino dealer I'm talking with currently sells 30 to 45 mowers per year. He claims to have sold ONE tailwheel from his parts dept in the last 3 years, replacing one that was damaged when the operator backed into a concrete culvert headwall.

I just bought a Woods BB720 and I'll tell you, made my field look like it was cut with a finish mower. Very stout design and build., I'm real happy with it,

FarmwithRhino, errr I mean FarmwithJunk, out here, the biggest thing you see is some occasional 1" stuff, everything is just grass/weeds, we don't get the brush that people do back east.
No one runs the 4" stuff (the heavy duty stuff), even the state.
It is a 172, not 176, I looked the other day, and it's a big monster for a 6 footer (and i haven't bent anything on it, except this poor design for a tailwheel
save your money, buy the bushhog
I wish I had.

In all likelyhood, I'll end up buying Bush Hog again. I like 'em and have a good working relationship with 2 different BH dealers. Rhino dealer is new on my short list.

I don't do much, if ever ANY brush cutting anymore, outside of a little bit on my place when I first bought it. Everything is grass and weeds now. But that doesn't change my wanting a heavy duty mower. By virtue of the fact they're built tough enough to mow 4" trees on a sustained basis, they'll stand up to a little abuse where light duty mowers won't always survive. That built in weight equates to built in strength in my book. And when you start banging a mower around behind a bigger, heavier, more powerful tractor, the mower takes a thrashing even in light weeds and grass. And a lesson I've learned about CABBED tractors... You're isolated from noise, so you don't have quite the same handle on what abuse the implement behind the tractor is going through. One thing that you deal with that is no different than us "back east" guys is chuck holes, rocks, and rain ruts. They'll do more harm than all the 4" trees you'll ever need to mow over. And they effect parts like the tailwheel more than those trees anyway. The more hours you use a piece of equipment, the higher the likelyhood of it getting "normal abuse". Buying heavy duty pays dividends in the long run.

Thanks for the heads up on the 15' vs 20' mowers. I didn't even think about the 20' being easier to turn on the headlands.

I haven't hit anything out of the ordinary.
In fact, I just figured out how I bent this one.
Putting it on the trailer
yes, that odd angle of putting it on the trailer bent it. (because I greased it before loading the tractor)
JUNK wheels
It's the 3rd wheel now (all 3 now)

All we have around here is grass, no real saplings like down south, everyone runs 1" stuff (even the highway dept)

176 (6', commercial, chains, 2000 bucks)
SE8A (8' commercial, 5000 bucks)

The 172 was the lightest duty machine Rhino makes. We sold them for $1600 last year, you got hosed. The 272 is the same as the old TW series.
The SE8A is designed only to cut grass witha a 40-60 Hp tractor and is light duty. You need a TW96 or a Turbo 96. Your dealer is selling the light duty stuff to you claiming it is commercial duty and it is not. There is nothing wrong with Rhino cutters you just have the wrong cutters for your application. The SE cutters and 100 series cutters are just King kutter style light-duty cutters. If you want a true Rhino you need to purchase the 200 series and above.

I have a 6' Walco cutter and have had tail wheel problems until this year. I first bent the wheel forks to the side a bit...got 'em straightened. Last year I not only bent the forks, I actually broke the weld at the top of the forks. Finally, my dealer diagnosed the problem.
I have really rough, hilly ground and, if the chain isn't loose enough, when I go over into a gulley, the wheel swivels around backwards, then slams down (facing the wrong way) when I go down into the dip. Basically, the full weight of the unit, plus the momentum of the tractor fall on the wheel and very rapidly force it to swivel to the back; eventually this pounding bends the forks.
The solution is to keep the chain really slack so the wheel stays on the ground all the time. When I back up, I either raise the mower or move very slowly and carefully so the wheel has time to swivel around slowly. The only real issue I have with this solution is that the very slack chain is a nuisance. It not only pounds the paint off the gearbox, it has managed to fall under the edge of the gearbox a couple of times, rubbing against the PTO shield. Getting it out from under there takes some toplink adjustment and readjustment (just an irritant, really).

I don't know if this diagnosis fits anybody else's situation, and it also doesn't explain why nobody seems to be seeing this issue with Bush Hog brand, but for what its worth....

I had a SE 5 and mainly used it for grass,, and I cut a lot of grass with it,
then moved up to a Rhino 172 and cut alot of grass and lots of Texas purple sage, had it sense 08 and going on my 2nd set of blades for it.

Now took on a 45 acre job of really realy thick Texas sage and some sort of mesquite type of tree only gets about 8ft tall but has tons of trunks that come out of ground in one spot, so my tractor wouldnt be able to take on a Rhino 272 but figured it could run the 260.

Now that mower is the deal. keep the power up at 2400rpm and it cuts thur this stuff all day long in 2nd low and sometimes I go to 3 low, oh using a Kubota L4400.

So for now im going to use the 172 for grass mainly and use the 260 for the thicker stuff. I would say if you had 60hp pto rating tractor that 272 would cut anything down,, they even got a 400 series.

got a friend who has turbo 96 from Rhino its can cut the 3in stuff all day long but it dont shredd it up as small as the 260, I guess its mainly due to the hieght of the mower deck is what makes the difference
