Unless you can find a three point cultivator the Ford will lack enough traction to pull an ordinary field cultivator over 8 feet. Do you have a row crop two row cultivator with the three point hitch. If the shovels were spread out evenly your Ford would handle it easily.

 

6-8 foot max. The 8 foot would need straight points at that. There are variables as always. You shouldn't run a cultivator deep, and for some reason S tine cultivators do pull easier than C shank.

 

I have a five foot C tine, six sharp chisel points and the 9n can pull it through Michigan sandy soil about eight inches deep in first gear. Blows smoke, though, so I don't crowd it. It's a seventy year old tractor, remember.

The N's that were sold in this area (Upstate NY med. clay with plenty of rock:hair ) had 6' 3pt ones with a C shank. Haven't seen any others here in this area. But if you are going 8" deep, you're not cultivating, you are almost subsoiling. If those weeds are that deep either should be cultivating a month sooner, or you are trying to achieve something else.

I AM subsoiling...almost like a chisel plow without the coulters. This is to break up compaction after discing the surface a week or so earlier in the springtime so as to create new area for a three year fallow area of nitrogen biomass....--or sometimes after a four week wait after moldboard plowing of three year old "fallow" of Ladino clover sod. Incorporates the decomposing biomatter for nitrogen and a new garden area.

I do use it to cover planting of oats, too.......then sow sweet clover, big red clover, and Ladino clover and cover by using a lawn rake. The sweet clover and big red are biannual, so I just let it all grow without mowing. The next year the ladino takes over for the next two years.
