5' or 6' rotary cut for a 3520?

They may have beefed up the 5' one, as back when I had mine I recall there being a more-substantial weight difference. I do not think the 3520 would have a problem powering either, but one does lose some maneuverability with the larger 72" in some cases. I suppose my opinion could be jaded by where I live. With lots of steep and tight places, having a larger attachment is not always better. Like many other posts, I suppose a lot of what the right choice is intended use and space. If the cutting is going to be lighter pasture or field work on flatter ground with few obstacles, then the 6' may be a good choice. If the cutting is heavy and on uneven ground with tighter turns and off-camber stuff (like I would have) then the smaller one is the better choice. I have had two 3720's and had a 5' one on one of mine for a short time. It had no trouble powering it through some pretty nasty cutting, so I suspect power is not going to be an issue either way. My concern is that the 3000 series machines, with their short wheelbases and relatively narrow stances, tend to "feel" heavy implements in back more than a 4000 series, for example. I know my 3720 occasionally would have it rear end jerked off line if I made a quick turn with my 5' and I would think that could be amplified with a larger cutter in terrain I noted above.

Hi LHS,

I just purchased a used 3520 that came with a 6' Frontier RC1072. The previous owner used the rotary cutter as a side-business, and wanted to sell the 3520 to purchase a larger tractor for a larger rotary cutter.

On my test drive, I ran the 1072 for around 100 feet and it seemed fine. I haven't used it since I purchased the tractor, but I'm assuming that it will work ok.

I have a 3320 and an King Kutter 5' mower, I set the entire mower to cut level at about 2" and do my 5 acres with it. It will bog down slightly when the grass is over 8" or so, but cuts really nice. I looked at the 6', seemed not worth the extra money to me. I have a 300CX FEL that I keep on, mostly to flatten the gopher hills as I am mowing, **** gophers!

I run a woods brushbull 72 on my 3520 with or without the fel without any problems at all. Power is never been an issue, i have mowed grass, cornstalks, brush up to about 1.5 inch.

Without the fel on, the front end will come up a bit going up steep grades with the deck raised, but I would guess even with a 5' it would do the same.

I was unsure at first when I bought the 6' since it looks huge compared to the size of the tractor, but now I'm glad i did. The extra width lets me mow much closer to fencelines etc.

Good luck

That 3520 has quite adequate power and lifting capacity for a 6' cutter. That's the way I'd go.

That said, I have an old Land Pride cutter I run behind my 4400 (Engine and PTO power is quite close to the 3520). This is a 5 foot unit I bought back in 2002 (when I had a 16.5 PTO HP tractor). I could easily use a 6 foot cutter. I just don't brush cut enough (anymore) to spend the money for an upgrade.

I had a 3320 a few years back and ran a 6ft Frontier cutter with no problems at all. I mowed waist high grass all summer long and it didnt miss a lick even with dull blades at times...:laughing:

Many Thanks to all who replied. It sounds like the 6 footer will get it done with no problem so thats where I'll focus my search but I won't rule out a great deal on a 5' if I found one. I'll run it thru TBN to see if its a reliable unit/good deal.
I will say that I will limit my search to the brand names of Landpride, Frontier, Woods, and Bush Hog. These are all brands that the local dealers carry within 15-20 miles of my home.
