I have a couple of questions with respect to a rotary brush cutter.First, I am looking to replace my bent PTO shaft. It is splined on both ends, 1-3/8" diameter. When I look at replacements, I see PTO shafts that have the splined 1-3/8" ends, but they say something like "metric 5 driveline". What is a "metric" driveline? Is that a size or a rating? Second, my brush cutter has a 1-3/8" splined shaft coming out of the gear head, no provision for a shear pin. I am assuming at one time this thing had a slip clutch assembly. Tractor Supply Co. has a replacement slip clutch assy that again is 1-3/8" (male & female) that would fit my gear head spline. However, it is listed as "metric 6" and is very heavy. This old bush cutter is a Hardee and the model number is E 60. I assume 60 is the width, but what would the "E" stand for? When I look at most brochures, they list standard/light duty cutters with a shear pin (with a slip clutch option). The medium duty cutters come with a slip clutch. The deck thickness on this Hardee is 11 or more likely 10 ga. We have an old Ford brush cutter with what looks like a 1" splined shaft coming out of the gear head and it has a slip clutch. What I am fishing for here is - what is the chance that my Hardee is a medium duty rotary cutter? I'd feel better about putting the heavy TSC slip clutch assy and HD metric PTO shaft on it without being to heavy for the gear head. Sorry for the ramble, I'd appreciate your thoughts. Thanks!
