Can't say I've ever heard that one. Where are you mowing at? A sharp blade is the best thing for bahai grass, may need to change them after 4 hrs or so of use. Make sure your deck is pitched properly also.

cjcland, by chance, is it a 48" deck? I had a 48" Scag that would not cut bahia worth a crap. I have a 54" Bobcat and 36" Exmark that cut it fine. I came to the conclusion the 48" deck is to short (front to rear) to allow the bahia grass to pop back up before it gets cut. I have changed the spacer arrangement on my Exmark to adjust cutting height, but have not noticed it cutting any better or worse.

it is a 48 inch deck, i worked for a guy who had a 52 inch toro with a 14hp mower and it cut great so i dont hink it was hp, i am looking forward to getting a better mower, not that my snaper has been bad i have only had to replace the clutch in 2 years(except belts and blades but i would really like to have to cut a yard once instead of 2 or 3 times, thanks for your input

I also have a 48" Scag. It has never cut bahai good at all, anything else is fine but not that. I was told by my dealer the longer the blades are, the better it cuts that wire. He may be right, my 72" Chopper doesn't miss any of it. My 50" also does real well so I believe blade tip speed has an awful lot to do with it as well. Scag came out with the bahai deck specifically for that reason I think. I have never talked with anyone that owns one so I can't comment on how they perform.

I have not tried to add an extra set of blades to mine yet, the spacer would have to be turned down to get the extra thickness on there. I'm sure that would help and with a wb it might not rob too much hp.

Just a quick question,is bahai that horrible
fine wiry grass that never cuts any good?
I think we have something similar over here
and even brush cutters can't cut it.Our mowers just tear it up.

YEP! It is a pain in the grass to mow, mulch and get rid of. You can actually buy seed for this stuff. The states plant it on the roadways because of its durability but once the chutes tassle out at the end, the seeds blow everywhere and it continues to spread. I can mow a lawn today and by Thursday the mess is right back up again. If you let it go over 2 weeks it will take you forever to get it chewed up enough to call it cut!

Pain in the grass!

The Scag distributor actually took my mower back. The dealer tried to use it and couldn't figure out the problem. They put a new deck on it, still cut badly. They gave me a loaner for 4 months and replaced it with the first Florida model available, still not much improvement. Sold it for a big loss 5 months later.

As far as bahia grass, or bahia weed I should say, Argentine bahia is much more manageable, at lest until June. Then it gets tough and wire like. If the customer has a sprinkler system it makes it worse. The best thing that can happen to bahia, is about mid summer, if you get a dry period, shut the sprinklers off. Let it burn, it will come back with tender, green, fresh growth.

Kieth, were you using the old standard deck or the new bahai deck? I was wondering how that new deck was working out in the real world, not the dealers world!

While I don't cut any warn season grasses, I have done many studies on blade/deck position. With a standard fixed deck walk behind, the height of cut can be adjusted in two ways; with spacers on the front casters raising and lowering the deck, and with spacers raising and lowering the blades.

I have found that under different conditions and different mowing configurations(mulching, bagging, and discharge) you can set the height of cut and blade combination many ways.

To summerize what I have found; If the deck is up all the way in the air, and the blades are in a low position, you can get better results while mulching. When discharging, I found that if the deck is in the low position, and the blades are in the high position, better results are achieved. For bagging, I found that a middle setting on both the deck and the blade spacers works best.

Now, with each of the above deck/blade configurations, you can use a variety of blades, high lift, mulching, low lift, double blades, double gators, high lift and gator, the combinations are many.

Each different combination has its place. Some work better in wet conditions, some work better in high grass, some work better when grass is under drought stress.

Homer, my first Scag was a standard deck, the replacement was a Florida model. I honestly saw no real difference except for steel plates welded to the front to keep the thing from lifting the front end when going up hills. It did little to improve that either. I think 48" decks, by design are trouble in Bahia. I don't know about the bahia deck, but bahia grass seems to be an ongoing problem for Scag. If I had bought a 52", I don't think I would have had that problem. I think the problem could be fixed by simply widening the deck front to rear.

I was told by the dealer, after I complained about mine, that the longer the blade, the better it cuts bahai. I tend to believe him now that I have larger decks with longer blades. I also think blade tip speed is a very big factor in a mowers ability to effectively cut the sh#$%%. I know I have not had near the trouble cutting it since I bought the Choppers and the blade tip speed is maxed out on them. Half the dealers you go to don't even know what I'm talking about when I say blade tip speed! The best way for my Scag to cut it was to slow waaaayyyy down, and then it might miss a little!

To prove how bad mine was I took my brand new Scag with brand new blades and my 5 year old Bobcat with old worn out blades to a vacant bahia 1/4 acre lot we mowed at the time. Mowed half with the Bobcat, left about 5 seed heads total. Mowed the other half with the Scag, it left about... oh 200. :)
