mower blade ??

Roy Suomi · Jul 14, 2008

Last year I posted this question with no results..I have a customer with a brush-hog..It's a 5' cut..However , under the housing is not the usual 2 swinging blade configuration..Up there is a single rotary mower blade..A full 5' wide..Last year I fabricated a blade from cold rolled barstock ..[ 1/2" X 5" X 58"]..Has anyone seen such a critter?? Or am I the only lucky soul ?? Well they called tonight and said the blade got twisted..Gotta make another..Suggestions on what material should be used if other than cold rolled flat bar stock....Thanks , Roy

Why not try to fit one with the swinging blades?

Take the original blade shorten it.Put pivoting replaceable blades on the ends.Mark

The winery I do work for uses this mower for grass cutting around the farm..They have a brush-hog with stump jumper and swinging blades..They want to mow grass so it looks like something..

I think spring steel would be good. If you fashon a pivoting blade on the end of the existing one, I don't think the centrifugal force necessary to keep the blade extended would be there. You could shorten the existing blade and add a sharpened extension on each end, but I would fix it solid so it doesn't pivot. Be careful to keep it balanced as much as possible. rw

I would call the folks at Flail-Master, 1.800.251.4020. If they don"t have a blade they may be able to have one made. They are nice to do business with and the prices are great. HTH Jf

You could try 4140 this time or maybe AR plate.

They are much harder.

I would talk to a steel house. Get a 4140 might work, then have it hardened. This will give you a hard edge or outside, but the metal wont be brittle. If you use something like spring steel(not even sure you could get a piece that big) it will be brittle and crack quite easily.

When I flip my Woods brand ditch bank mower straight up verticaly at idle it will hold the blades straight out.My swinging blade JD 709 will mow grass that looks like a finish mower cut it.Mark

That is a stalk shredder. Looks like a brush hog (rotary cutter)and a few years ago were common among cotton farmers. Many were belt driven but some were gear driven just like a brush hog. I think they were too fragile to use to cut brush and heavy grass

I would avoid making mower blades.This puts liability on you.When I did mower work I used blades from a maker that included a million dollar policy.

I'd use 4140 or the like, high strength low alloy. Mild steel wont hold an edge. The swinging blades are for hitting rocks or stumps. You could fit end blades of 4140 in a swinging configuration, with a grade 5 or 8 bolt, double nutted, upset or staked, (to hold it from loosening) to allow it to pivot. The straight blade makes me think the mower was meant for crop fields that are known not to have rocks or stumps. I wouldn't use it in any kind of woods or weeds in rock or stump country.
