Hello Oliver,
Of course, the Loftness and the US Mower models look less productive. But in this case, it's not only because of the technology they used. A 40-something-hp machine can only do that much volume of mulching.
I see two solutions to get more productivity:
1st:
You put a small power unit on the JD 50. That would probably make your JD longer-tail, helping manoeuvre heavier head. Or one could try to crimp the power unit on top of the excavator, but that involves looking into security issues (visibility, non-obstructed escape from cab in case of emergency). In either case, I haven't mention the cost of such a power unit. I'd guess a 60-hp power pack wouldn't be much less than 30000$. Of course, you could build one yourself with 2nd-hand parts, but then you're investing your time in it. In the end, I'm not sure how viable a solution that would be, unless you find a niche market for very small excavator-mounted mulching operations.
2nd:
We build a lighter model: smaller teeth, smaller diameter drum, +/- 50 cc motor, lighter frame. But for this, we would need to see if there's possible interest from more than a few persons for such little beast. A new mold, even for smaller blades, is far from being cheap, let alone engineering to design the head...
Readers, that would be of interest to you? Email me at
frederic.denis@deniscimaf.com. Depending on the amount of feedback I get, I'll pass the request to engineering.
Let me know what you think
