On my B 2710 I widened the blade from 6' to 8'.
Through bolted a 3' piece of 2x2 angle iron to the cutting blade on each side of the blade. Then took some 1/2 thick rubber conveyor belting an bolted it to the angle iron and the plow blade.
After 3 yrs it is still working fine.
The increased width makes a tremendous difference.
Sry but I haven't figured out how to post a pic.
