Tiller killing tractor

1.8L 3 cyl 45.6hp at pto

My gut feel is six foot is max for this unless in soft sandy soil like where I am.
As long as you are covering your rear tires totally, anything more is a bonus.

If you aren't going to hit tree roots, and you don't have a lot of rocks to deal with, which I'm guessing
is the case for you (?) I think TooRow sized his tiller just fine.
If he doesn't go too fast and the soil isn't like concrete and...

Rebel Series Rotary Tillers | Rhino Ag
nice tiller and properly sized per their specs

Really? I ran a five-foot tiller with my JD 870 (25 hp at PTO) for years and it never knew it had anything behind it.

Rhino Ag REB72R is a REVERSE ROTATION[ TILLER.

TOOROW should have specified this in opening post as REVERSE ROTATION TILLERS are somewhat outliers, I speculate 8% (+/-) of tiller market. I am in North Florida where our soil is sandy-loam. My Kubota dealer never inventories reverse rotation tillers. Reverse rotation roto-tillers are special order by customer request.

Reverse tine rotation means tractor would have been trying to lift obstacles when it stalled. No wonder.

No change in advice. Loosen the bolts applying tension to the slip clutch a half turn. Have at the tilling again. If in doubt about the ground, walk it before tilling, carefully watching for potential obstacles. Flag potential obstacles. Repeat.

Till only moist ground; not dry.

I speculate TOOROW will shear tines off the tiller way before he damages the tractor or the Cat 4 driveline on the Reb72R roto-tiller. Cat 4 driveline is heavy-duty by standards of this forum.

A former neighbor ran a 5' JD tiller behind his Kubota 185DT. (17HP at the PTO) He tilled a lot of gardens with it, when I was looking at the tines were merely spikes. It also had a 3 speed PTO gearbox though.

This thread reminds me that I really need to service and adjust my tiller’s slip clutch. The tiller sits outside, and I’m sure the clutch is seized up by now.
Implement width for soil engagement is very dependent upon soil condition / type. I ran a 5’ tiller with a 25hp pto tractor, and in undisturbed clay it struggled, but at slower speed it got the job done.

I run a 6' King Kutter II tiller on my DK 35 just fine.
The slip clutch needs to be adjusted to work properly with your machine.
I have my slip clutch set to slip just before I run out of power or if I hit something that jams it.
The slip clutch also needs to be serviced occasionally to continue working properly.

Because that clutch can literally stick together, certainly loosen it quite a bit, then let it slip for a second or two (use marks to verify that it has) then adjust to factory specs. My slip clutch instructions say to do this after any period of inactivity. Mine also squeals like a pig when it slips under heavy load!

it shows a range of 45 to 65 hp for the next tiller size up, putting OP's unit at absolute minimum for his pto hp.

Since we have no idea of what TooRow's soil conditions are, this is all speculation.


Now if one of you runs a 7 foot tiller, next size up from OP's 6 foot, I'd be interested to know what pto hp your tractor has.

There's no question if you are careful and run slowly and have the right soil conditions you can run these tillers with less hp.

I'll stick by my gut on this until someone who has larger tiller experience chimes in. Particular on a reverse rotation tiller.

I have two slip clutches;a bush-hog and a tiller.Service every spring,not that difficult.The bush hog requires I find some resistance to make the clutch slip;the tiller I just drop to the ground.I have lots of rocks so run my tiller with the discharge flap wide open.

you make it sound easy, can you explain what you do? Is it just backing some bolts out, under tension, and not too far? Do you make one full bolt revolution (or something) in reverse and then test?

went back and read this: Loosen the bolts applying tension to the slip clutch a half turn.
You really only need a little movement and I question in general the use of lube in that area.
We don't want rust but you don't want to lube your very needed friction away.
Yeah, I never have any rust, but then my tiller won't spin...
