We are looking to buy another self propelled grinder, currently we have a Carlton sp7015, it does a good job grinding has good power, but makes a huge mess, chips fly everywhere. The operator spends more time cleaning up than anything else. We used to run a Vermeer SC 502, tow behind that didn't make anywhere near the mess, Just looking to see who has what and what kind of mess the others make compared to the carlton, Looking to switch to a track machine also. Thanks for any info!
