Flail Mower Let's talk flail mowers

Leonz:
Question about belts.
Numerous times you refer to green kevlar belts in this thread. Are you referring to single ribbed kevlar v-belts, or banded (2 ribs) v-belts?
I cannot find Kevlar v-belts in a banded b54/55 size anywhere.
Anyone have a source???
Is it OK to use two separate kevlar v-belts on a Ford 917 flail mower?


Thanks!

Hello sjssmith8688,

You could try the Gates catalog for a 2 ribbed V belt but I am not sure if you want to stomach the price.


AS LONG AS both V belts have the same exact lot number they will be fine. if your belt dealer tries to sell you two belts that are not the same lot number walk away and find another V belt dealer

Do Y blade use less power than the airplane wings??

I don't htink so.

the hammers have more rotating mass and chop stuff up much smaller than Y blades.

What I find makes the biggest difference is wet vs dry grass. Wet really takes teh HP, and tall wet or thick grass...you gotta go real slow.

I run a 78" woodmaxx from a 30hp pto ck3510HST kioti.

Anecdotal "evidence" suggests otherwise.

Physics is physics. If you're doing more Work (more chopping) it requires more Power. That's where the unit Horsepower came from.

More rotating mass in teh hammers than Y blades - so it takes more power to get them up to speed, and when they encounter an obstacle they're larger mass is more momentum (like a larger flywheel) helps them keep going - BUT - when they do slow from say, taller/thicker grass, it will take mower power ot get them back up to speed than the lighter mass of the Y blades.

Also, one might want to do the math - the cutting face of 28 hammers is how many inches? vs the Y blades. Does the angle at which it meets the grass make a difference?

Anecdotal "evidence" suggests otherwise.

Here's the new to me Ford flail mower that I just picked up yesterday. I bought it from a local used equipment dealer who did a great job painting it, the wrong color!

I set it up on the 3930 today and took it out for a test drive. I really like how it chops everything up so fine. Cuts real short though. Am I spose to be running this thing right down on the side skids and back roller? On uneven ground it's chopping in the dirt.

That would be the Ford 907. Uses the same blades as the 917, but different hangers.

Your roller is set to it's lowest setting. Good for soccer fields, bad for anything not flat. Set it to a higher setting and try it again. The skids are there as a means of protection to prevent bottoming out, not for riding on. The roller should be carrying it.

907 you say? Thanks! The tag is not very readable. So I'll look to drop the roller, and I guess adjust the top link to get the side skids up and out of the dirt.

Thanks!

Thank you, Dave!

As much as your company's name comes up . . . I'd think you would get ahold of the owners . . . .

The tag doesn't give you the "907". It tells you their code for the model and size. So "22-124" tells me that it's a 907 6 foot. They were made between 1964-1972. Messicks has a parts diagram for the unit and some parts are available through them. Just search 22-124 in New Holland Agriculture on the left side of their home page.

The bolts circled in this picture are the roller adjustment.



The roller is currently set at the lowest setting. Move it one notch and check the result. If it's not satisfactory move it to the last notch (only 3 options).
