Horse power vs tiller width

[Sawyer Rob]

We run an 8' tiller with a 33 HP engine tractor. But we always disc first. Which I would with any tractor.

I don't know what kind/brand of eight-foot tiller you have, but I'd make a bet to you for a "serous amount" of money that you can't run my 80" tiller for one hour with your 33hp tractor, without your tractor over heating badly! I'm not talking in cement either, farm soil right here on my place.

In fact, it won't run my six-foot tiller for same! NO way, NO how!

Take me up on my bet, come try, but bring plenty of money to leave behind, I can always use some money. lol

I've been looking to get a tiller to use with my Kubota M6800. PTO HP rated at 62.

Two "rules" of thumb in this thread:

"Rule of thumb is 1 foot of width per 5 pto ponies." 62 HP/5 = 12 feet of tiller

"Over here we work on 1 inch per hp." 62HP = 62" or 5 feet of tiller

I don't have a lot of experience with tillers but that seems like a lot of variation in tiller size between the two rules.

62hp tractor will "properly" run a HD 6' tiller pretty much anyplace, continuous duty.

In gardens or lighter soils, even a 7 footer...

Naw, this tractor has a compound double low. It's a LONG brand tiller with gearbox in the center. Tractor has 4 & 3 on trans. Put both in first, it will do it.

Tiller width is one thing, rotor diameter is another. A large rotor type in 10 feet width may require 150 hp to run it. that is 15 hp per foot.

But for your 6800 I agree that a 72" wide tiller with 7 to 8 inch working depth would be about perfect size. That would have about an 18" -to-20" rotor diameter. Six cutters per rotor for about 54 cutters total.

Not with a HD tiller it won't, I don't care how slow you go as long as you put it in the ground. lol

Puzzled a bit by the comments. Seems it "all depends" on the ground, the ground speed, the depth, the soil, tiller diameter, etc., etc. .

My 32 hp CUT HST Deere works just fine tilling with my 60" 3ph tiller. Never entered my mind that maybe there were not enough horses to do the fine job that it does. Tractor doesn't overheat, so maybe I'm missing something here. ??

Biggest thing you are missing, has already been mentioned, that is, "exactly" what the specs of "the" tiller are.

Like I've said over and over on this forum, not all tillers are created equal!

Been doing it too long.

I run a 4' tiller with my new holland s14 in hard clay. Sometimes I have to make multiple passes to get to the max depth, but it does the job.

I won't waste my time on you any farther.

it is spelled "further" and so much for your judgment.
