Just picked up a triple-bag bagger for my 48" 27hp, haven't even gotten it out of the box yet.
The engine died last August, while under warranty. But, with 350 hours on it, neither the manufacturer nor the extended warranty folks wanted to cover it. Finally got everything settled, but by then the rains had set in. Finally got the mower running again last week, still haven't had time to start mowing. The grass is getting tall enough to hide the dog.
Normally, I just let the clippings fall. But with this amount, it'd choke out the lawn. And I sure don't want to rake 4 1/2 acres....
