    I am looking into purchasing a new 48in scag walk behind this fall. My only question is that they only offer the 48in belt drive with a 16hp kawi? Many of my accounts are treated/irrigated, and have super thick healthy grass, is 16hp gonna be enough power to mulch properly and leave nice clean stripes? If not I am considering just the 36in with the same motor.....Any input is appreciated! :)

    I would demo the 48 with the 16 hp kaw and see if its going to work for you before you buy.

    thats plenty of power i have a 14 hp on a 52 and its just fine i would strongly suggest that you go with a hydro drive mower

    In my opinion if you're mulching lush thick turf, it's going to strain the engine.

    Take it for what it's worth, I always go with the biggest engine I can get.

    I would look at the SWZ hydro, they have engines that go up to 21 hp.
    Because if you mulch I don't think you'll have enough power. It doesn't hurt to have a little extra power. Plus the hydro is just simply better. Have you looked at the Exmarks?

    I use 15hp Kohler's on my 48's, power to spare, thou they are belt driven...
    As for thick wet grass bogging it down, you'd need a 8-cylinder to make sure it never does that, if the grass is tall and thick enough a 28hp isn't enough.

    I'd like to know where the line on fuel consumption is drawn, too...
    Because my 15hp consumes it seems like a quart an hour, thou probably closer to 1/2 gallon...
    The 25hp on my Z eats 2 gallons / hour in comparison, just never made sense to me.
    But what I do understand is somewhere around the 18hp range is where fuel consumption increases dramatically, just don't know exactly where, or why.

    Thanks for everyones input! Now I am leaning torward a Scag hydro 36 with the 16hp kawi. After discussing it with my local dealer he felt that with me primarily mulching I should have a highest output motor possible for the deck size I want. Plus he insisted that I go hydro.....

    You wont regret the hydro, trust me its a million times better in tight areas and backing up. The 36 is probaly a better choice if your mulching all the time.
