Grass rows, are very annoying how to avoid? Using the MMM.

You don't want the grass clipped fine for bailing. My Enrossi sickle bar is good for bailing. If it's accumulating in the center of the deck, it's too high, cut more often. MMM decks are stamped and not very deep so they can be overloaded easily. Another thing to look at is that the friction washers are properly installed on the blades so there's no slippage. My bx takes 2 washers stacked and blade bolts need to be tightened with a torque wrench to the spec in your manual. A flail with knives may give a nicer cut in your case.

Yeah I bought some generic gator style blades that were only 3/16" thick. I had to buy 3 additional washers to get them to tighten. For what the dealer charged me for 3 more washers I could have bought a correct set of blades. ;) A while back one of my bolts worked loose and I had to retorque it.

possible mowing options..
1) hire local kid to cut the 3.5 acres of grass ?

2) whoever lives with you, might cut the grass ?

3) reduce the 3.5 ACRES to something manageable, maybe 1-2 acres ?

4) fence the 3.5 acres, buy 3 goats or sheep ?

3.5 acres is a bunch of hours on a B-Series and they don't last forever, and your current end result isn't what you want anyway. The right tool for the job would help, like a high-end zero-turn or if sticking with the B a 3-point mower if you've not a lot of obstacles.

I think a better option is killing off the current grass and putting in a no-mow fine fescue, at least farther from the house.

Our side discharge on the cub cadet makes a hell of a mess if we don't cut weekly. Really need to look into getting a bagger for it.

The rear discharge on the tractor though distributes nicely and doesn't make the yard look bad with trimmings.

Does that mower deck have an anti scalp wheel (roller) in the front center? Maybe needs to be replaced or set a bit lower so it keeps the deck up off the ground?

Open the side deflector and slow your rate of travel.
I know according to the manual you should not be doing that but it works for me, especially when the grass is higher. Nicely throws it out the side distributing it over a bigger area, no big lumps any more.

Although some will do it, recommendations with too little information usually doesn't solve the problem. I recommend you try various things to gain e xperience with what difference they make. While you shop for more equipment, sharpen the blades. If you aren't certain how blades should be sharpened, remove and take them to a professional. Before removing blades, look close to see if they turn cw or ccw. DON"T EVEN THINK about looking under deck while tractor id running. It's easy to tell which way blade has been turning by shiny edge. You might find the problem to be blades installed up-side-down following last time they were sharpened. Take notice of angle which pro ground blade so you know how much angle to use when you grind them next time. Park on level surface,set mower to preferred height then using ruler,tape or blocks of wood, adj so that right and left are same (level). Set front of deck 1-2" lower than rear, that's right, all rotary mowers are supposed to be lower in front (1/4-1/2" on push mower) ( 1/2-3/4" on lawn tractor). Sharp blades make a world of difference.

Here's some of those trial and errors for gaining knowledge. Use same throttle setting but next lower gear to reduce ground speed. On outer perimeter farthest from home, lift deck so it leaves grass longer on 4 or 5 passes. Notice whether grass clumps less. After deck has been dropped to customary height AND ground speed is reduced, take note of whether there's less grass clumping.

After 3-5 days you may very well find grass mowed higher looks as good and possibly better than that cut lower.

Good point, I can confirm that.

Another thing I forgot: grass should really be dry when cutting, most liekly somebody mentioned this already.

Yes it always pills up in the middle of the MMM, i have to lift the deck mow over it then backup and mow over it again but of course on the next pass it gets stuck again.

Never new of the Estate Rake it looks like the rake they use before baling hay, maybe i should just make hay out of it and buy a mini hay baler.
Are you running the RPM’s up in 540 PTO range? I mow with a BX2380 with MMM and the only time stuff tends to get stuck is if the grass is tall and I don’t run the RPM’s high enough. One field I mow tends to get a little tall before I get to it so I use a bungee to hold up the plastic deflector so it scatters it out more. So really never a problem with cut grass getting stuck under the deck and I never rake. Is your deck clean underneath? I had a previous mower that the deck would get plugged up and then I would have this problem. I would clean it out then it’s fine for a while. With my BX, the deck stays clean, never a problem. Just thinking out loud here as to what could be causing your problems……
