Wet cell or dry cell?

[mark103]

Hi guys

I have been thinking about running hho on a lawn mower, because I find it a bit too much work to cut on the grass without having canvas box (I know that I am lazy lol)

I would like to know if i would need to run wet cell or dry cell?

If I should go for dry cell, i would like to know how do I work it out how many plates I would need to make for 3.5hp on four stroke engine?

Do I need to run the battery on lawn mower?

There are two good lawn mowers i would like to buy, but i am not sure which one of them I should go for.

i am thinking about buying this mower:

or this:

I am not really sure which one i should go for? I might have a little problem. How would i be able to handing the wet\dry cell and the battery on the mower without being moving about?

Any advice would be much appreicated.

thanks in advance

That's a lot of money to spend on an experiment! You should buy a used mower and play with it first! As you will find that you have to take it apart in many pieces. For such a small project you could save a lot of money and get what you need from a wet cell without a problem! Yes you will need to have a battery, some sort of power to the cell.
You would have to have a dryer and separator any how so movement isn't an issue.
Smack cell would suit you just fine ! Then graduate.
