I visited my Cat sales rep today in respect to possibly buying a 268 to run a mulching head. The guy tried to point out the pro's and con's of using a mulching head with a skid steer rather than a dedicated unit such as a Gyro-Trac. His conern was if the skid is used "mainly" for mulching, the machine would run at such high rpm's putting a huge strain on the engine and hydraulic system over the course of say a year, the machine would be almost worn out. I know he meant well and he may be right in some regards as the Gyro is using a 160hp motor. But, I'm not looking at trying to shread 12 inch trees, but I do plan on using a skid if I get one, mainly for mulching. I hope I've explained his concerns correctly to you guys. Does anyone see a lot of validity in what he was saying? Thanks!
