I wanted the WIDEST Single deck RFM I could buy for my Farm.
I was concerned about it turning slower blade spd than my Bush Hog 84" at 18,266 rpm.
The Befco 14,998 BTS didn't cut as smooth as I was use to :-( ..... So
I ordered the 30mm Larger Gearbox Pulley for the smaller 90" mower, and replaced the stock 250mm pulley.
The stock belts fit jus fine with a gearbox adjustment.
It Now Cuts MUCH SMOOTHER with Finer Clippings.
You can hear the difference & see the clippings being slung out much farther.
I can run one gear higher where my ground terrain allows it.
I read the Govn't regulates manufactures blade speed. I wouldn't doubt it.
I'm estimating my blade speed should now be around 16,650
Btw, ONLY Whitting-Higgins makes a 4-tang socket to fit these spanner nuts. I wasn't paying $240.00 for a socket. Yea I kno - use a punch.
I did & it cracked the nut removing it, so I ordered a 30mm-1.5 HEX Jamb nut from Fastenal with red loctite.
The 3 blade spindle nuts that hold the pulleys on, are 35mm-1.5
These are impossible to find in a thinner HEX nut.
I found that a Honda CB1000 motorcycle rear axle nut is this same size BUT I didn't remove these.
I was so excited with the Superb fine cut - I jus had to share. Thanks
