Hello all,
I have a 5 year old Rhino SE7 rotary mower that I need to either replace or sharpen the blades on. I have owned the mower since it was new. Up until recently I have only used the mower 3 or 4 times a year mowing less than 5 acres each time. I looked at the blades the other day before I started a mowing job and they seemed pretty dull with a few nicks taken out of them.
Can I resharpen these blades? I have the operators manual, which recommends sharpening the blades down to 1/16" at the cutting edge. Has anyone done this? How often do you do it, or do you just replace them when they get dull. Is it it best to grind them? I have a vertical mill that I think I could set the blades up on and mill the new cutting edges with a carbide face mill.
The original blades are 28-1/4" from the tip to the center of the mounting hole and 4" wide. I can buy new blades from my NH dealer but they seem pretty expensive. I found some at TSC that were the correct length but only 3-1/2" wide. How critical is it that I get the exact same blades as original? My operators manual just gives a part number for the blades and the bolts/nuts, no description. Anybody know where I could find a good description of the blades and bolts?
Thanks,
Tim
