Blade for brush cutter

[DannyLobster]

I busted the blade on my 30 inch brush cutter on my Gravely. I'm having a hard time getting the blade off. I have not tried a big cheater yet, but have tried a good sized wrench. I got to thinking, before I ruin my wrench, anyone ever taken oine of these off?
Any thoughts on getting the nut to turn?
I am holding the blade still and turning against the blade,
If I am successful in getting the nut loose, Is it going to spin or will the bade hold the spindle adequately?
Are replacement blades available?

Thanks,
Dan

If you have the older 30 it's gonna spin, I think the last time I took mine off I beat on the wrench with a hammer, but once it came loose it spun right off. Wedge a board between the blade and housing so ya have both hands free to work.

Ooopps, blades are still available for the right hand style, not sure about the left though. If the gearbox mounts to the deck shell with 6 bolts it's a right turn. Or check the casting number on the gearbox if it's a model 106 it's a right turn.

Here is a link to tell you how to identify your mower. Untitled Document
If it is a left turn mower I'm not sure if you can still get blades. Try Gravelyparts.com to see if they have any.

It appears to be the 52-57 LH. Does the Left hand nut mean I should be turning left to tighten rather than left to loosen?
And will probably not be able to get a replacement?.

I did look at the site Solo posted and they do list a lefty.

I can't tell ya if the threads are right of left, I have only had the 106 gearboxes and they are normal,,,,,, righty tighty, lefty loosey.

Turn it left to break it loose. If Richards doesn't have one try,

Or sometimes I see them listed on ebay.

So it was a Left threaded nut. Left to Tighten - Right (clockwise) to loosen.
I was able to get it off and now just need to find a replacement. If anyone does need to do this on this model, I was able to grab onto one of the spacers with a pipe wrench to stop the spindle from turning. It must be unround.
Thanks so far.

This reminds me of a funny time watching my father ry to remove the lug nuts off of out '68 dodge truck.
Who'd have tought they turned the other way!

Dannylobster- It doesn't sound like you have an owners manual for your equipment. You can download (for free) owner's manuals and illustrated parts lists from OldGravelys.Net: : Check it out. - Kris

Danny
Sorry for the misinformation. Glad to see you got it off.

Hey No problem You were right on with everything else. I was able top get it off, get a new from Richards, and get it on again. Silly me took it off the tractor and put my blower on for the winter. If we don't get some snow soon I am gonna switch em back!
I took a picture of the old versus new. I wasn't sure I had the right blade the old was sooooo worn down.
Thanks to all for the help
As usual TBN saved the day.

Danny, might want to check your slip clutch adjustment on that mower while you have it off.

 

[krislu]

Danny- Is that the 3/8" thick blade ? What did you hit to break that ?

- Kris

 

[DannyLobster]

JS - Not sure where to start on the slip clutch adjustment. There wer no manuals for the mower, just parts lists.
Kris - Yes It is a thick blade. Not exactly sure, I think it may have been an Ash sapling.

 

[js5020]

Well personally I would disassemble the slip clutch to make sure the clutch discs are not stuck to the drive plate then reassemble, the info I have says to loosen the lock nuts, tighten all 6 bolts into the back plate then back each bolt off 1/2 turn and lock each bolt into position with locknut. Did the encounter with the sapling stall the tractor or just the mower?

Dannylobster. I have a 52-57.brush mower. Do you find a blade? If not Last year I maked one with soft steel plate. (3/16 x 3.5x 36 in.) It is not the best. But work very good!
I use two blades. Better mulching effect! Better job! Better speed! You can use high range speed. Good luck! Oldmech

 

[oldmech]

Danny! I think you have the good blade! As mine! For SAFETY CLUTCH ajustement! Easy Way! With a feeler gauge (.025 in.) between coils of springs You adjust the six springs. I joint picture. Thank ! Oldmech

The blade is a monster. I am amazed what it cuts. Stilll not sure how it broke. I was debating a brush cutter formy new MF 2310, but this does such a nice job I was glad I was glad I was able to get it repaired.
Thanks for the tips on the clutch adjustment.
