    The Velocity deck really is amazing. It cuts great in almost all conditions. There is a reason it has been unchanged since 2006. I ran them for years but just recently switched to Gravely with the X-Factor deck. I get almost as good wet cutting as the velocity and a better dry cut due to smaller clippings. Another great deck is the JD 7 Iron. We have to have a deck that cuts good in most conditions and I hate double cutting. Its a pet peeve of mine and a huge waste of time and money.

    After all the BS, I thought you were done with BB?

    LOL. Thought BB would have bought that clam back. Wonder if they fired that rep?

    all you deck experts take a look at the aerocore deck and tell me what you'd modify (if anything) to get a better cut and dispersal. also interested to see how you think it performs just by looking at the picture. i'd post one but can't at work.

    Is the Advantage deck on Scag's 36" as good as the Velocity?

    IMO, that angled down steel at the rear of each chamber hurts the cut far more than helps it, because it interrupts/disturbs the high speed air flow created by the lift sails. The sails lift the air immediately at start up of the deck blades, and since there's no where for the air to go once they start spinning and lifting, the only alternative is for the air stream to go out the side, which creates a high speed discharge. Having that angled down section disrupts all that and slows the discharge down a bit, which in turn can help create clumping in wet conditions. Plus, that angle is just another place for wet grass to stick and collect. I'd also get rid of those two little angular pieces of steel at the point of the rear skirting in between each blade.

    This deck is a close copy of the ICD and JD mod in design of the front baffle shape, and the MOD in the design of those two little pieces of steel at the rear skirt in between each blade. I have enough experience with the MOD to know that they need to go.

    I have thought all along that the angle at rear of deck causes problems, unfortunately the only area i can remedy that is in the middle blade. If you look at scag's deck though, they seem to have that area as well, but only in about 1/3 of the area of each cutting chamber (unless that is just some sort of stiffener, hard to tell from pic).

    the wright has good discharge velocity, but leaves long clippings and a poor pattern. It clumps weeds, and in very tall grass will tend to ''puff'' grass out the discharge chute, not necessarily tight wet clumps but just tufts of grass that don't look leave the lawn looking great. What i believe to happen with that angle as well is that it forces the air back over to the front of the deck, and takes all the clippings with it. As a result 90% of the clippings leave the discharge chute at the front and are thrown in a straight line from the deck. there is no ''fanning'' pattern to speak of. If there were a way to modify the dispersal pattern and ''fan'' out better, i believe the deck would be much better, if not great. It leaves some stragglers also but this might be remedied with a smoother airflow. the tightly baffled decks such as the ultracut seem to do best with leaving no stragglers at all, but they aren't too good in wet conditions. This aerocore deck actually stays very clean, even in damp grass. (cut a yard full of weeds you'll be scraping the deck though, no surprise there). If someone could figure out a way to easily remedy the dispersal pattern I think alot of people would be much happier with this deck.

    the advantage deck looks just about the same as the deck on my 36'' wright. no complaints about it really
