Replacing tines on a King Kutter rototiller

[Baby Grand]

If you have a pressure washer, clean that tiller out real good before you start.
This will make the work much, much more pleasant.
Helps to have the tiller mounted to the 3pt hitch & raised.
Also helps to remove the rear gate.

Of course, it goes without saying that all safety precautions will be observed.
This includes blocking the tiller from the bottom, if it's lifted up.

Once clean, leave it until it's dry, then give all the nuts a good shot of Kroil, Liquid Wrench, ATF/Acetone, or whatever your poison and let it set overnight. After the solvent has had a chance to soak in, loosen the fasteners by holding the bolts & turning the nuts until they break free. As sixdogs said, a pair of box end wrenches, long pattern, if you have them, will be your friend on this job.

Should go easy as pie; simple as cake.

Thanks guys. Yep, already planned to pressure wash first. Hopefully will tackle this soon.

Rather than blocking it up, I put a 3" ratchet strap around the top of the ROPS and hooked to the tiller. Tie the door all the way open and it works for me. I sit on a plastic chair and wrench away.

You will find --if you don't overthink it--that tines are no big deal and will take a only a few hours. Piece of cake.

Last winter I changed 110 tines that were 2 5/8" apart, on my slit seeder. There was barely enough room for the wrench and, because it was so tight and difficult took me a week of off and on to get them changed.

And concerning the loosening solvent of your choice (I prefer PB B'laster or Kroil). I've had parts that seemed to be welded together. I spray or dribble a little on, let it sit a couple of days, attempt to loosen, repeat several times. Occasionally it's taken weeks and 4 or five "bathings" along with "bangings" to get a particularly stubborn bolt undone. So if you've got the time let it sit.
And I ripped this

A study done by Machinist"s Workshop magazine in their April 2007 issue looked at different penetrating oils to see which one did the best job of removing a rusted bolt by measuring the pounds of torque required to loosen the bolt once treated. If the study was scientifically accurate, it turns out a home brew works best!
Here"s the summary of the test results:
Penetrating oil ..... Average load

None ...................... 516 pounds
WD-40 ................... 238 pounds
PB Blaster .............. 214 pounds
Liquid Wrench ...... 127 pounds
Kano Kroil ............. 106 pounds
ATF-Acetone mix....53 pounds

from PB Blaster vs Kroil - Yesterday's Tractors, don't know the validity.
