Get a plow for Mr. Smith

Get a plow for Mr. Smith is a side quest in Fallout 2.

Detailed walkthrough
In Vault City, behind Cassidy's bar and Dr. Andrew's Clinic with the half working Auto-Doc, there is a stagnant family with neither the resources to leave town, nor to earn their sustenance.

Speaking to Mr. Smith will reveal a possible way to help them earn a living; Happy Harry has a plow for sale, which would make farming much easier. Happy won't let the plow go for the goodness of his heart, though, as he asks for $800, up front. A Barter check (51% required) will reduce the cost to $600. Buy it when you've got the funds.

Rewards
Tell Happy to deliver it to Mr. Smith for a Desert Eagle .44 and 250 XP. If you get greedy and ask for a reward from Smith, you'll only get 100 dollars and the XP.
