Mowing Has anyone run a 90" mower with a JD 3520

[DHAUG]

I have a 3520 cab tractor that puts 30hp (I think) to the pto shaft. My dealer says it will turn a 7 foot 3pt finish mower or a 15 foot batwing finish mower. The batwing is out of my price range, but I would like to get rid of my MMM in favor of a 3pt mower, and I can not decide between a Landpride 6 foot, or a Landpride 90" mower. If my tractor will have enough power, I would like to get the 90" mower. Has anyone run one of these, or something like it behind a 3520?
I like these two mowers better than the 84" that landpride offers because of blade tip speed, but I am open to suggestions.
Thanks in advance for your help on this.

I just bought a 84 in landpride mower for my 4310 which has 27 pto hp. I can bog it down in some very heavy grass but no more than my 5 ft brush cutter on the same grass going about 7.5 mph travel speed. About a foot high heavy grass going up a hill.
I think a 90 in mower would be no problem.

How is your cut quality mowing that fast? With John Deere's 72MMM I can only go about 3.5mph if I want a good cut quality. I rarely cut grass more than 7" tall. That is why I am interested in the 90" mower over the 84" mower (it has a higher blade tip speed).

I think you would be pushing it with a 15 foot batwing. You would slow down to a crawl.

But I think the 90" finish mower would be fine.

7.5 MPH? Holy cow that's flying. Does it actualy give a satisfactory cut?

Hi:

I ran a 15' wing mower with my 3720 cab (There is a thread with pictures... ).
I mowed at up to 6mph, had to slow down to 4mph a couple of times.

You'd have absolutely no problem running a 90" with a 3520. I've actually have an 84" RFM ordered. Anything larger than 84" (The JD 90 or 110) I looked at had a much lower blades speed and most had swinging (rotary cutter type) blades that wouldn't give as good a cut quality?

Does the 90" landpride your getting have fixed or swinging blades? What's the blade speed? (Most I looked at were below 15,000 for that size.

The blade tip speed is shown at 18,500. I beleive these are regular non-swinging blades. Here is the website that I am getting the information from.

thanks for the advice, and I would love to hear opinions on this particular mower.

That looks sweet. 3/4" to over 5 is a great range. I wish I looked at those before I ordered my 84" Frontier (Made by Woods). I just looked at Frontier and Woods. Woods makes a 90 but it's swinging blades, etc.

18,500 is faster than my 7 iron MMM (is around 18000). You'll get a great cut with that. Tip speed also helps when you are cutting high stuff as it mulches it up better.

Do you think I will get a better cut than the 72MMM I am using now? I have the large R-4 tires and wonder if the extra tires (the rear's) running over the grass before the mower gets to it will affect the cut drastically.

I don't think that that is going that fast for a rough cutter.... I go along in 2nd in our MF135 with Multi Power and I think that is about 10MPH. (But that is with a 6 foot cutter which is pretty small for the tractor)
