I picked up a 48" rotary mower, a Gannon convertible scraper and a screw-type log splitter from a guy a few weeks ago. I finally removed my backhoe and hooked up the mower just to see how it ran.
I'm not sure what brand mower it is, the previous owner gave it a "DuPont Overhaul" and painted over the tag... never understood why someone wouldn't spend 5 extra minutes and a nickel's worth of masking tape to mask off data plates, but oh well!!!
I put it in 540 rpm, and drove it around but it seemed to be running awfully slow... I put the PTO in High (2000 rpm) and it seemed to work better, though the blades were so dull I could have done better swinging a baseball bat. Is 2,000 rpm the correct speed for it?
There's two blades mounted on a large disk underneath. Each just have a large shoulder bolt on one end and swing freely (one was jammed with grass).
Is it worth trying to sharpen these type blades or should I buy a new set?
