tiller stalled b7800

[tnmx]

Just wondering if this is normal or if something wrong with tiller or tractor...

I was running a 60" tiller off my b7800 (the tiller has a clutch mechanism not shear bolts). well i hit a 3" diameter tree root - it tore up the root but stalled out the tractor. i thought the tiller's clutch should have caused the tiller to "stall out" rather than going backward through the tractor pto and stalling the tractor itself.

only happend once - but wondering if normal and can this damage the tractor or pto system.

A 6' tiller on b7800 is allot of tiller to pull.
The 7800 is at its limits with that size. I'm sure its nothing uncommon to stall the unit 0n a 3" root.
I pull a 2 point 16" plow with mine and its about all she wants to handle.
Advice, watch for rocks and BFR's. It should be fine.
Which reminds me, I need to look up the HP requirements for a 6' tiller. I've been looking to buy for myself.

Good luck and Enjoy.

You might want to check the adjustment on your tiller's slip clutch.

Depending on your soil conditions, I would have to agree that a 6' tiller is too large for a B7800. I know my B2710 would have trouble with it in hard soil.

Uh guys . . . he said it is a 60" tiller . . . 60" divided by 12" = 5'



A 60" tiller should work fine for the roughly24 PTO hp that the B7800 puts out.

TNMX,

I have had the same thing happen about three times with my B7610 and Woods 52" tiller. I have my slip clutch adjusted as loose as it will go, and the stalling still occurred. The slip clutch is there to protect the tiller, not the tractor. So I'm sure the tiller is fine. No damage to the tractor either as far as I can tell.

But things sure do get quiet all of a sudden, don't they?

A tiller ain't a root puller. A 3" root is pretty darn big, it could have hunderds of feet of root attached.

I have learned a few lessons over the past few years and Number One is SLOW DOWN. Let the tractor crawl so it chews and spits out the tilled soil, don't drag that spinning tiller. If there's roots, just skim the surface and chip away at the root.

I've stalled mine a time or two, yep hit a root or two and also getting into the really hard pan on the garden the first time or two the soil was tilled. I haven't had a problem with that happening the past couple of years. Actually last year I plowed the garden and then tilled it a few days later.

I stalled my Mahindra 2615 (23HP PTO) with a rental tiller (52 inch Kubota) and was worried that it was something I did wrong. I pre-plowed the field and thought I had gottent the big rocks but apparently I missed one that was able to lodge itself up inside the tiller.

I'm glad its happened to others. My tractor doesn't seem any worse for it. The sudden silence is kind of unsettling though.

I have a 52" <font color="orange"> Kubota </font>tiller that I use behind my B2910. The slip clutch had a setting that was to high for my tractors PTO horsepower. Dealer had a sheet for modifying the slip clutch. It will still stall the engine if I do not push clutch in quick enough when hitting something solid. The slip clutch does not have the bolts and springs that my rotary cutter has. Had to take slip clutch apart and remove a disk spring.
It sure was a surprise when the tractor stalled almost instantly. /forums/images/graemlins/blush.gif

i am really impressed with how well the tiller chunks up the ground. i found that when hitting rock to set the rear door (technical term...) 1/2 open so that it throws the rock out the rear rather than grinding it around and around when closed (fist sized rock and some larger). as for the root - well, thought i got them all with the backhoe - but apparently not. as for avoiding roots - impossible as my yard is surrounded with trees and i am chewing up the sod to reseed. same for the fields. the seatbelt is extremely important with the tiller attachment as when the tiller hits something solid - it jerks the tractor forward - that was more surprised the first time compared to the silence of stalling out. in all, i would say the 30hp B7800 can handle a 60" tiller - but like others said, in low gear and just crawl forward. first pass on virgin soil/sod goes down about 5" and makes smooth topsoil.

I stalled my BX1800 twice this spring running a 48 inch tiller. I too thought I had removed all the big rocks, but two were buried and I found them with the tiller.

The slip clutch didn't "slip" and stalled the tractor immediately. I now have the slip clutch adjusted properly.

So far, I have not noticed any damage or problems with the tiller or the tractor. But the sudden silence does get your attention rather quickly!!
