MyAGER,
Deere has two different baggers for the 4100: a 3-Bin bagger with vacumn, and a hydraulic dump bagger with vacumn. The 3-Bin bagger holds 10 bushels, the hydraulic dumper holds 13. I got the 3-Bin bagger with my tractor last July, and it works very well. I'm in the process of trading it in for the hydraulic dump bagger. The hyd. unit uses the same vacumn pick up, so it should work very well too; presumably the hydraulic dump will work as expected. Every Deere implement I've gotten so far has pretty much worked as I expected... I'd say talk to a dealer - that should get you going.
Happy Tractoring,
Dave Wells
