    Bucket question - John Deere 490e

    I own a 1996 John Deere 490e excavator. It has a 32" bucket on it with teeth. I just bought a farm and need to trench in a mile of 10" water mainline, and the seller recommended I do it with a 18" bucket to avoid tearing up the fields too much. My question - how do I go about finding an 18"...

    My accountant had me re-look at the ERC credit as new guidance came out that you don't have to actually have had sales go down, but can qualify if you were simply somehow impacted by the government shutdown. Tons of businesses are getting very big money here.
