Lawnmower modification question

I made a thing I have hooked to my mower before that I call my leaf picker upper.

Leaf Picker Upper

It's a 6 inch tube made out of #10 cans and some stove elbows, that dumps into a bag the mower pulls.  (I have a different bag for it now, modified to work better)  
It clogs if I try to mow up too many leaves at once.
I'm thinking weird compost thoughts, and debating putting it on to see if it will pick up grass without clogging too much.
It's a fair ordeal to put it on, several hours.  I don't have a lot of extra time right now, in fact I'm at negative extra time and I need to stop sleeping or something to get everything done.
I admit I have never dealt with a normal mower catch bag for this machine. I have a tight gate I have to take the mower through, and any attachments have to fit within the footprint of the mower to get trough it. I scrape both sides of the gate. The other gate is 1/2 inch smaller, no way I can get through it. So I have zero experience with normal catchers.

What odds do y'all give that it will move grass cuttings to the bag without clogging up? Any guesses?  I HATE to put a lot of work into getting it on only to find out everyone but me knew it wasn't going to work.

We have a professional lawn vacuum for when the grass grows ridiculously fast in the spring.



It has a second impeller which helps to suck the wet grass up the flexible hose to the impeller and then up to the top of the black pipe. I don't use this machine. It's a pain in the ass and clogs easily. What you're trying to do may work better if the grass is shorter and dryer.

Hi Ms. Pearl;
I suspect you're in for clogging trouble unless your grass is short and dry.
My  E-Go mower has a bag and it is constantly plugging, of course, my grass is tall and usually mowed in between rainstorms.
It's a cool modification though.
If you were not so busy it would be worth a try.

I've had about a foot of rain in the last week and a half. Not short at all. Which is why I hate to waste it.
Probably still wet, or if it's dry, that'll mean it's even less short by then :(
Hm...
Maybe I'll just mow it into windrows and rake it up.

I'm not a civilized enough person to mow my lawn if it's short, I have better things to do than groom grass for no good reason.

Probably a no-go for right now. My whole experience is with side discharge; I've never bagged or mulched. As stated above, the grass throws out better if you're cutting less, and/ or if it's dryer.
On the other hand, something I used to see at my first job (at a hardware store) was high lift mower blades. It seems they're designed to move more air, which would be a benefit for you here. They're made in several styles, but I found you a picture similar to the ones I remember most. (That doesn't mean they're the best, I probably remember them because there were two colors, and my school colors at that.)



The ones I'm thinking of had another piece of metal bolted onto the three holes of the lift section, making it even higher lift, by maybe ¾" or so. That piece happened to be red.
High lift blades can be found online or, I would assume, you can still get them at a good hardware store. There may be some made for your mower. If they sell a bagger, I'm sure there are. If you're looking at a hardware store, though you can compare what they have to your old blade(s). If it bolts up and the length is right it'll probably work.

Yeah, I'm in the camp that thinks if it clogs on leaves, it's going to clog faster and worse on grass.

This just occurred to me: how about the output side of your rig? How porous is that bag? As an experiment, when it's just beginning to clog, what would happen if you unzipped it? If that allows more airflow, maybe you could improve flow by replacing a section with the same amount of window screen or plastic canvas?

Thought about it last night. What I'm trying to do is quick hot compost down some alleopathic plants (sunroots) that are known to sprout from cuttings, so they won't sprout, then use it to pack along an edge that I can't mow and hate to deal with the grass that gets in there. Hoping the alleopathic doesn't break down as fast as the sproutableness (Is that a word?) The idea with the bagger was to keep the chopped stuff under control as I collect it.

I have a huge flattened cardboard box I abuse, I'm going to stand it along the fence, and use it to control the mower throwings and rake onto a tarp for transport. The grass and leaves I need to jumpstart the composting I'll mow onto the box too, and drag them on a tarp to the compost area.

Thank you for your advice, all of you! It'll help me not put work into something that won't do what I need.

:D
