It's a Scag system, installed by dealer. It was $3000 more for unit. The 3 buckets are large and we'll made. No plastic parts on buckets. The lid is heavy plastic with steel reinforcements. The blower is very solid with belt driven pulleys that attach to main deck pulleys. The large hose attaches with hose clamps.
The unit is worth the money. Mine is 5 years old, used for leaves only on my property and still is in perfect condition. I save a lot of time using this system over bagging on other store brand grass catchers.
There are baffles under the machine that were changed. There was labor to install everything. Once fit to the machine it takes an hour or so to completely add or remove it. I run just the side discharge for summer time. If you were to purchase this from Scag, you would be very happy with it.
