Hey Guys,
We have a customer that has an over sized mower attachment (don't know the real name of it) for an excavator. He uses it to cut grass, shrubs and trees up too 10" diameter with.
We have tried O1 and 4140 Treated and drawn to 55, 50 and 45 Rc.
The cutting edge itself we started at 30 deg but I noticed it was wearing into a steeper pitch. Last set I cut @ about 37.5 deg.
We coated the last set with tungsten carbide hard face and treated to 50 rc on the blade and used the 37.5 deg angle on the cutting edge using 4140. He was able to get about 10 hours of run time before he had to flip the blades and start using the other side which was a big improvement from the stock blades that came on the machine "2 hrs".
Any of you guys have suggestions to make the blades last longer; material cutter angle, coatings ect?
Thanks for reading
