Brush hog incident.

John_Odom · Apr 23, 2004

One of the things I like about a flail mower is that they don'y throw stuff as bad as a bush-hog. When I was teaching in Illinois a kid was mowing the lawn while we had faculty meeting. He was using a big Woods mower, and the main arm holding the blades broke. It came through the 8" block wall, through the group, hitting no one, and burried itself in the opposite wall, half way through the block! I've been a little scared of bush-hogs since then. We found the piece had been partialy cracked for a long time. I now turn my bush-hog over for inspection at the beginning of each season.

I am rehabing a ford 917 flail mower, and have completed everything except the rear guard. I will make either a chain guard or use a piece of conveyor belt if I fan find one. I finished building the PTO shaft guard and it stops with gentlest hand pressure.

( How do you plan to get rid of all the unwanted stuff? )

The real junk, like bedsprings get cut up and put out for the trashman. We have trash pickup, and they will thate the equivalent of a refrigerator in junk at any time.

The "good" stuff I'm keeping. I'm about to get a welder and am considering building a forge, so I'll have plenty of raw material.

( I don't have any closeup shots of it, but here is a shot of some before I cut it down with my mower. )
Thanks Gatorboy. No need to post a close up as this gives me a very good idea of what you're up against. Those things sure get tall! I can almost feel those thorns reaching out to grab me now. I'd rather deal with my blackberries! Thanks for the pics, John

I've said this so many times to people who wander up while I am using my rotary cutter:

Brush hogging IS NOT a spectator sport!

One time I had to stop my brother and sister-in-law who were setting up lawn chairs to watch me up close. /forums/images/graemlins/shocked.gif

Ok..now I am concerned. I am suppose to pick up my rotary mower next weekend. The property we are buying has a lot of saplings and tall weeds mixed with some rock. I thought the blade on the rotary were suppose to kick away from things rather than throw them. What does the highway crew use to mow the median? I always thought those were rotary mowers but I am just learning.

( What does the highway crew use to mow the median? )

Some use rotary mowers some use flail mowers. Even your small push mower will throw a rock/golf ball, etc. if you hit one. If you maintain your property you should be able to SEE any rocks before you hit them. Medians get maintained as well, and the guys cutting them can see objects and raise the mower decks as needed. I think alot of these flying objects are coming when one is cutting brush, pasture that is highly overgrown and objects can't be seen.

Yes and no. ( and gatorboy explained it pretty good.. )

Yes your cutter blades will pivot on the stump jumper.. and if you did say.. hit a stump.. technically the blade can delect and clear it.. most likely shearing a pin in the process.. and the stump jumper is just what it says it is.

Mostly though.. if your big 540rpm rotary cutter hits a rock.. half of the rock will turn to dust.. and some may be ejected from under the mower. Don't look for those big blades to deflect and fold back under anything but the most extreme circumstances. ( Irrestible force hitting immovable object.. )

Right. The pivot is there to prevent the machine's self destructing when you hit something big. For small rocks, the blade will barely notice it, but the rock sure will. Think of how pool balls behave.

Yeah, that is exactly how I felt when I started following this thread. My first question was, was that an aberration? After seeing all the different posts I realized the answer to that question was a resounding no. My next question was then, Well, should I still get one? Aftet careful consideration I have decided yes. Maybe a flail mower would be better maybe not, but for the money I have, the Rotary cutter is the best option. So then the final question, How should I deal with this potential killer? Same way I deal with the lawnmower I have. I don't just run the thing through a rock field or over junk, I walk around the lawn first, picking up toys and cursing at the kids. When the rotary cutter arrives I will walk the property again. I have done this numerous times over the last five years and I am 99.9% sure there is nothing out there but I will walk it again anyway, especially the frontage portion. I will then cut very slowly. I am not in a hurry to die or kill anyone, I just want the weeds and brush cut down. And of course it will all add up to Seat Time. You can bet I have also checked my insurance policies as well.

The funny thing about this thread is that it has actually made me safer with my little Costco lawnmower. Who Knew?

One more time in unison, Thanks TBN
