HELP! Craftsman 900 series rototiller shear pin

[redneckhillbilly]

what substitute grade bolt could be used safely to replace a broken shear pin on the tines, I was thinking a grade 5 might work.

I looked online and couldnt find any spec on the hardness of replacements and Im nervous to put a bolt in there thats to hard

Is it a shear pin for the whole tine assembly?

 

[redneckhillbilly]

there is 2 sets of tines, on on each side of the transmission, total width of both tines is 17 inches

Plug in the model number of your tiller, no dot after the first 3 digits.
Get the part number for the shear pins. You may get lucky and they will state the specs on the pins.
Do a little searching online, you may be able to find a common hardware replacement for them, like a bolt.
If not, you can usually find proper shear pins cheap on ebay or Amazon by searching for the part number.

Would a grade 2 bolt not work? If you are constantly breaking those, go up to the grade 5.

I have a good selection of grade 5 bolts, I am worried they might be too strong, I am going to check the hardware store today and look for some grade 2 bolts, I just couldnt find a definitive spec on them so I think grade will work, if the shear on some light tilling I will just order rrplacements for my tiller
