I was just wondering, is there a way to mount a set of dual rear wheels on my 8N? Or will that be likely to start breaking stuff within ? I'm needing a little more weight and flotation at the same time. I've got a Wagner FEL, AND the back-end gets kinda squirlly when I get a load of dirt.I've already got weights mounted in the back wheels and I HAD calcium carbide in the tires, but when I got new back tires,the tire shop didn't put the stuff back in the tubes, so now it's a-lot lighter. Any ideas guy's? Oh yeah, supposedly no-one around these parts has the proper equipment to put the calcium carbide in the tubes, even if I had some.HELP PLEASE!!! THANKS IN ADVANCED!!!!!
