Mowing Torque Bush Hog Blades

[srcaaga]

I have a Howse 6FT bush hog and the manual does not indicate the bolt torque for the blots attacting the blades to the circular "stump jumping" plate. Any suggestions woold be appreciated.

I think German torque should be used, good-n-tight.

1000ft-lbs is about right.

1000 or did you mean 100? Thanks.

I think theyre 1" high grade fine thread. Depending on bolt Grade, bolt torques on that size range up to more than 1000. Gr 5 is about 600. Gr 8 is about 1000. I would not go less than the Gr 5 torque recommendation for the diameter the bolts are. Measure them and go from there. ... or just hammer the heck out of them with a strong 1/2" impact gun. That might leave them just a little on the loose side.

Rather then guess, contact Howse via the link on their website.

I'm quite surprised that torque value isn't in the manual.

I use a 1" ratchet set and a 6 foot bar on the ratchet handle. I put both arms into it. A 1/2" rattle gun is not going to do it, and them bolts are expensive, so don't risk losing one!
