Well I am going to try increasing the blade speed.
Turns out the old smaller 42 inch deck pulleys will fit on the 46 inch deck spindles. So I'll be replacing 6.25 inch pulleys with 5 and 3/16.
Stock is right about a 1:1 ratio. Now they will be over driven to about 4,000 rpm, about a what, 15% over drive? That required a 5 inch shorter belt. Everything is ready to go for the test tomorrow.
Will it work or will it just chew up belts?
As an alternative or maybe even an upgrade to the fisher barton eversharp blades there are blades made by meg-mo they are miniaturized 4 blade "bush hogs" because the blades pivot and don't have to be flexible to absorb impacts so they are really hard and really high alloy.
They don't stock any star pattern blades but they say they will make anything.
