BUSH HOG or RHINO?

[jbrumberg]

There always seems to be a lot of confusion when posters start talking about horsepower requirements and light, economy, medium, standard and heavy duty rotary cutters. Farmwithjunk's Post #10 really answers the issue. It does not take a lot of PTO HP to turn any size rotary cutter if the RC is balanced and in good condition. The HP is needed to cut the vegetation. This "Rule of Thumb" (that we all tend to use)was "gleaned" from the "Compact Tractor Bible" (2006)- "The power (required) is typically 2 horsepower per foot of cut for light-duty rotary mowing and 5 horsepwer per foot of cut for brush hogs capable of smashing 2-inch-diameter saplings." I would have provided more informaton about the book, but one can getter more useful information here at TBN and this information is free ! Jay

Hi Travis,

I researched around on cutters, also. I have a Kubota L3830. I am not sure what the weight limitations are on your tractor's 3 pt. lift, but that is something you need to consider also.

I bought a Squealer 172 recently and like it. I weighs near 800 lbs. I have cut 2" stuff with it without problem. Have to go slow and keep the RPMs up. But, mostly 1" roadside type of stuff. Now, I am not an expert, nor a professional, but I am very satisified with it. I got the slip clutch and paid $1450. I had to wait a month for it to come in, since none were in stock. Too bad we all don't live closer to try each other's stuff out before buying...

The larger heavier duty models weigh a lot more, and require more horsepower to operate. And are more expensive. For most use, I think the medium duty is just fine. Woods or Rhino are good, too. But I haven't used them to compare. Best as I can remember, they were a little more pricier but weighed about the same.

Hi guys
How would Bush Hog 3008 8 ft cutter compare to the Kodiak 8 ft rotary cutter? Both heavy duty?
thanks Bruce

Bruce the 3008 is much more machine...I think it is probably the best 8ft mower on the market...the new Rhino Turbo 96 is a nice piece also.

Hi
Does any one know Bush Hog and the Kodiak run the same blade tip speed ?
Does any one Know what Blade tip speed is on both Machines ?
What is the blade tip speed on a 4 Ft Bush Hog or the Kodiak ?
Has any one had any problems with the Bush hog leaving tall grass not cut in the middle ? I am having a problem with a Kodiak 8 ft twin blades ?
thanks Bruce

Hi
I left a word out Does Bush hog 3008 and Kodiak 8 ft. twin use the same blade tip speed ?
I am still trying figure out what the problem is the we are using 640 rpm
tractor . The 1 st gear box is a 1.22 ratio then the two gear boxes is 1.48
ratio. any ideas ? thanks Bruce

Bruce, I am not sure if they do or not. BUT....Go to Bush Hog® and KODIAK MFG., Inc. and look at the specs on the models you need to see.

Hi Travis
Thanks for the info.
Has any body had any problem with twin head cutters leaving grass stick back up after you mow?
If you did what did you do to stop it?
The reasion I was asking so many question, I though it might be blade tip speed?
By the way the pto speed is 540 not 640 sorry about that.

It is probably your travelling speed. It is quite common to try to mow grass too quickly. One of the terms we see a lot on golf course care is "frequency of clip" which basically refers to how many times a blade comes in contact with a bedknife (a "clip"). More clips in less space results in a better cut. Easiest way to do this is slow down.

On the other hand, you also have to bear in mind that a brush hog ain't really made for a quality cut... A flail mower might be more in line with what you want, maybe even a finish mower if the terrain will support it. But try slowing down your travel speed and see if that helps.

Oh, BTW I love my Rhino, to get to the original poster's question ...

Well rocks from fist size to Truck size of course you canot see them until
you hear them then it is too late. New sub divisions did up rocks and store them under grass and weeds head high. Then want the grass cut smooth.
So it can look petty!!
Thanks Bruce
