I have a love hate relationship with our Ibex baler. Sure wish the pickup header was a little wider and that it had gathering wheels. I did learn a trick through trial and errors about making heavier bales. Watch your guage and just before it gets to the yellow line, stop moving and let the baler spin. Tightens the bale up somewhat. Then start in again. Been pretty good at getting 50 pound bales.
I found a place that sales gathering wheels for small balers. Salesman couldn't state that it was a direct fit with the ibex, but said it should fit with a little modification. $600 for a set. Not ready for that outlay just yet.
I'm selling my Frontier sickle and focusing on my old JD #8, gathering wheels will be a huge benefit. Hell, the holes are already punched in on those balers.
