I just purchased a Goossen CS5100, with a 13hp Honda motor. I know this is an older model, and I have the original manuals and part numbers. What I want to know is how these parts compare with the newer models, I am thinking the blades may be the same with new part numbers. My part numbers are as follows:
Shredder knife CS-23-00
Chipper Blade CS-121-00

The part numbers are the same for models PTO CS1000, and Gas engine CS6000 the 18hp version. The new Goossen model numbers are PTO CS5400 and gas engine CS1800. The part numbers for these blades are as follows:
Shredder knife 905008
Chipper blade 905007
Are these parts interchangeable with the older part numbers? If not is there a source for the older parts?
