The triple bag option give you the most versatility. You can remove each bag and dump them where you want, however bear in mind that each bag when full can weigh up to 40LBS. With the clam shell system, the only option that you have is to dump where you can get the machine into and out of. Grass clippings when dumped on the ground stay soft for a long time and you can get the machine stuck very easily.
With both systems, the collection blower mounts on the discharge port of the deck. It can easily be removed and the plastic chute installed when you choose to not use the collection system. Both collection systems include a different baffle configuration under the deck, front mounted weights, the collection blower which is driven by V belt from the R/H deck spindle, an 8" diameter flex hose, and either the triple bag or clam shell on the rear.
I have the triple bag system on my Tiger Cub and I use it about 80% of my mowing time. At all of the places that I mow, I stop the machine on a solid area, remove the bags and carry them for 15' to 30' and dump them. I wear a dust mask, goggles, a hat and hearing protection as ZTRs are dusty by nature and the collection system makes them worse. The last time that I checked the price on a triple bag system it was $2,500 plus tax and installation, so do your homework, make an educated decision and keep in mind that the blower makes the machine about 9" wider and a lot noisier!!!
