Hey there everyone, I have a 2010 john deere 910a and a protera bagging unit on it. I bought the mower with a 2 bag bagging system on it but I needed to get something for the leaf season cause well the bags just filled up way to quickly, so I got a protera HV18 dump from seat hopper. The new HV118 still uses the john deere power flow, and tube to get the clippings into the hopper. Now the issue that im having with it is when ever I cut and bag leafs, a lot of leaves blow out from the right side of the deck and not get sucked up and into the hopper, it did it with the 2 bag system but not nearly as much. I took a video with my gopro to show you whats going on. Any ideas on how I fix it? I can do stripes with my mower which isn't really that big of a deal but when Im trying to suck up the last little bit of leaves in an area it just kinda blows the leaves all over and I have to do a coupe of added passes to clean everything up. Nothing is damaged or missing, and the tube is not getting plugged either. Here is what im talking about. Thanks for your help

Try throttling down a bit, to half throttle or so. For me it always seems that when trying to suck up leaves at full throttle, the blades are actually acting like a fan, and blowing the leaves instead of sucking them up.

Not familiar with the Deere, but does the baffle under the deck adjust?

NO.
However, OP, get a set of either OEM medium lifts like those used on the 915B/Z720A or better yet IMO, the wavy mulching blades from your dealer. Not only will you get more into your bagger before it's full, you'll get a LOT less blowout from them.
I tried to throttle down but that didn't help out at all.
Ridin green, I will give those blades a try, do they sell they wavy mulching blades for the 910 or do I have to get them from a different machine? Or should I say if I ask my dealer for wavy mulching blades for a 910 will they know what I'm talking about? Haha thanks for your help

Many don't have a clue about the wavy mulchers. They'll tell you they don't exist even. They do. Just tell them you want the wavy mulchers that come with the mulch kit for a 910, 920 etc for the same sized deck you have.
I don't have time right now, but you can look up the blade part number on JD parts .com. If you can't find it, post what size deck you have and if I get time later, I'll look it up.

I owned an exmark with bagging unit years ago and had blowout like that. Especially on thin or bare areas of a lawn. I never attempted to fix it. Seemed there was a gap between the side blower and deck. Maybe sealing off the gap would have worked. Could have also been my blades, they were stock high lift.
That's the main reason I switched to a walker mower.

^^^^ There isn't a gap between the blower unit and the mower. I checked and made sure that its nice and tight to the mower.
Thanks a lot, I will give them a call and see what they say. I have a 48 inch deck 7 iron, no MOD. With the blades being a mulch type design blade, will the clippings make it over to the right side of the deck to get sucked up? Thanks a lot for your help.

What level on the dial are you cutting at in this video? I've found that when doing leaves I have to stay around the 2-2.5 mark for it to do any good.

As the leaves fly into the bagger they will clog the screens and reduce suction its just the nature of the beast. If you look at the video it gets worse over time so thats one issue. Another is you favor the right side of the deck and do not make the left where you make your cut into a line. The left side will tend to suck in the leaves better where the right side will tend to repulse them. Also in nearly every pass the vac motor was over the leaves themselves and never on clean grass so much of that blow out could be caused from that. I just mowed my own lawn today course I didn't have leaves like yours mine were 10 times as bad I filled the collection system 14 times. So I do have some idea what your going through and many of my passes had to be done more than once but with both my fradan 18 self propelled blowers down I didn't have much choice but to bag.

You need M136185 wavy mulcher for a 48" deck
Go here, then click on spindle and blade, then scroll down the parts list to 18 where the various blades are shown. The part # above is the wavy mulcher to ask for. My mulchers have no problem getting everything from the left side of my 60" deck and out the chute across the lawn a long ways when discharging, so you shouldn't have any issue with that.

I went to my dealer today and asked if they had a set of wavy mulching blades for my mower, just to give them a test, they said they had a set so he went and got them and before I bought them I checked to make sure they where the same number that you gave me and sure enough they actually knew what I was talking about. So tomorrow I will get the new blades on and test them out on my yard, see if and how much they make a difference. I will report back.

I can tell you this-
With my MOD closed to mulch with the high lifts that came on it, it would blow more leaves away from the deck than it would suck in under it. After I switched to the wavy mulchers, it now sucks them in from several inches outside the deck.
The design of the blades creates airflow in two planes. One vertically from the lift sail and then again back downward from the inner wavy area, and the other horizontally also from the lift fin since it all can't go in the upward direction alone. That is why they work for mulching so much better, and should also help your situation as well.

It should be interesting to see if it makes a big difference, due to I have the same problem as well. Please do report back. Thank you.

Same issue with leaves blowing out on a 36in gravely walk behind.
Please post back the results.

With all this added turbulence under the deck, how do these blades affect your RPMs compared to your other blade choices?

The RPM's are actually slightly higher on my tach. The blades are only 2.5" wide vs the 3" stock blades or G6's.
There's not more turbulence. Just different. The sails don't move nearly as much air as high lifts, which is another reason for less blowout.

You have a double stack pulley on the discharge side of the mower that your belt from the bagger attaches to. What is the diameter of the top pulley? In a lot of cases they will give you a smaller pulley so the power doesn't drain. I put a larger pulley on mine and made a big difference.
Sorry I didn't get back soon, but I got the new blades on and tried it out. It did help out a bit but I still have a decent amount of blow out. What I think is going on and I'm going to do a little bit of testing with this weekend if I have time is that the hopper is to much of a sealed unit and air can not escape fast enough. So the blower can only blow stuff in as fast as the air is coming out and if the air can't get out fast enough the power head can't keep up with the deck and it kind of creats an air damn, sense the air can't get sucked up by the power head, it go else where aka out the sides of the deck. So what I'm going to do this weekend is disconnect the tube from the hopper and go cut some grass and leaves. So the deck will still be set up as if I'm going to collect but instead of the leaves going in the hopper they are just going to get blown out the back. It will be messy but the leaves and air won't be trapped so I will see if I have the blow out issue, if that makes sense. But if I do still have the issue then I know my theory is wrong but if I don't then I need to figure out how to make the hopper breath more. I will take pictures and videos and report back.

Usually the tube coming into the hopper has a curved end on it to direct the clippings etc to the far side bag first. If that is missing or altered, then the debris may very well be blocking the airflow at the exhaust screen in the hopper. Worth checking into for sure.
Another thing- if you have the cloth bags, wash them thoroughly with a pressure washer, but don't get close enough to damage them, They are designed to allow the air to flow through them, but they can get clogged with dust/dirt and the airflow is cut down dramatically. When new, the bags come with instructions to wash them somewhat frequently.
