if you rototill i have a question

[tjg911]

this year i'm adding manure to the garden. i have a rear tine toro 5.5 hp 18" wide whose tines turn in the direction the wheels turn ie it is not counter rotating, i've used counter rotating tine tillers and detest them. each fall the soil is hard to break into as most of it has been walked on and is very hard packed. i have found that it is best to till 2" deep then 5" then the max, i think 8". trying to go 4" then 8" is hard as going down 4" on the 1st pass is difficult. tossing alpaca manure on the garden is going to make this harder on the 1st pass.

so when you till in manure do you just spread it and till or do you till some distance into the soil then spread the manure? if the former how deep do you go on that 1st pass?

thanks,

tom
