I have a Toro Dingo 322 with the slandered 4 cu ft bucket on it. I manly use it for mulching and it works a lot fast then a shovel and wheel barrow but i think it would be a lot faster if it had a bigger bucket. I was searching around the net and found some of the Ramrods taskmaster different bucket attachments. They have a 13 cu ft bucket and a 18 cu ft bucket. I know that the dingo will can lift the 13 cu ft bucket but am unsure that it will be able to handle the 18 cu ft bucket. The 13 cu ft bucket is 48 inches wide and the 18 cu ft is 52.
