I have a new to me Kubota B7800 with a soon to arrive Kubota front mount snow blower. This is my first winter with the tractor. I live in Ontario Canada and because my driveway is about 1/4 mile long with VERY steep hills I have put trig / stud chains on the rear tires. I want to be able to tow or mount a spreader on the rear to spread sand with some salt. I'd heard good things about the King Kutter spreaders sold at Tractor Supply and spoke to them and King Kutter today. According to King Kutter their is no way other than reducing the RPMs down to almost nothing to reduce the spread width on the spreader. At normal RPS the spreader will spread material out to about 40 feet. My driveway is only 10 feet wide. According to them, even with the RPMs greatly reduced their spreaders will still spread the sand out to about 20 feet. At 20 feet 50% of my material will end up in the bush. Any suggestions? Having just bought the tractor, blower and chains I'm trying to spend as little as possible and still get the job done. Thanks in advance!
