Baffle for 48" Exmark TTHP?


LawnSite Bronze Member
I am having problems with when I am mowing air blows the leaves ahead of the deck and doesn't allow them to get bagged. Is there a baffle that is made to reduce this? I am running doubles (hilifts and gators) and bagging with an accelerator bagger.
Any help would be much appreciated.

Go to the Exmark web site and ask them what the part number is. When I went to my dealer to order one for my Lazer he said he never heard of such a thing as an "anti blowout baffle", but he ordered it. It did help somewhat, but I still get some blowout.

Blowout in coded in eXmark DNA....

In this case we are really talking about "blowaway" and believe me, I understand what you are going through. Things you can try to "lessen" it are the blowout baffle, going back to single blades, testing various blade styles, and testing various deck pitch/rake adjustments.

I have the flanged baffle kit on my 52" TTHP and it helps a lot there is still some blow out when the catcher is almost full on the OCDC is down. Here is a part number list from the old Exmark forum.

P.S. I don't think the prices are accurate.

The only pics I see on that page are for an "anti-blowout kit" and a "flanged baffle kit". I too have a 48" tthp and the only listing for that deck is the "Anti-blowout baffle kit"

Anyone know what this looks like? how does it vary from the other two styles and which works the best?
What blades are you using?
I would recommend standards or low lift.

Hope that helps, littlenic

Also, try using only the gator blades. It does help to lessen the blowout.

Here's your answer!

Install skirting on the front of the deck. Use indoor/outdoor carpeting. Install so it just touches the ground and your problem will be GONE.

Weird, I have zero blowout with my 48" TTHP.

Then again, I almost never use a bagger. Perhaps using one is restricting the airflow out of the discharge, and that pressure has to go somewhere...
