After leaving the House Eaton returned to his farm, also holding the position of postmaster in the hamlet of Eaton (sometimes spelled Eatons or Eaton's) Corners.[12][13] He was a member of the New York State Senate (3rd D.) from 1829 to 1832, sitting in the 52nd, 53rd, 54th and 55th New York State Legislatures.[14][15][16] In addition, he was an active militia officer and attained the rank of Brigadier General.[17][18]
In the mid-1830s Eaton moved to Lockport, New York, where he purchased the Nathan Comstock Jr. House.[19] Eaton was Lockport's postmaster and president of the Lockport Bank, and also served as a member of the New York Bank Commission from 1832 to 1838.[20][21][22]
In the late 1830s he relocated to the village of Black Rock (now part of Buffalo), where he resumed farming, was a clerk in the federal revenue collection office for the Niagara district, became a lumber dealer and was President of the City Bank of Buffalo.[23][24][25][26]
In the early 1840s he served as a Special Agent of the United States Post Office Department, ensuring that postmasters and mail carriers did not use the service for illegal purposes.[29][30]
Eaton was active in several agricultural societies and farming organizations, including being a founder and President of the Buffalo Horticultural Society. Agricultural journals and fair records from the 1820s to the 1850s are replete with entries on his prize winning cattle, pigs, poultry, asparagus, pears, apples, and other farm products, as well as notations on the prizes his wife won for her peonies and other floral arrangements.[31][32][33][34][35][36][37][38][39]
Eaton died in Buffalo on August 22, 1857. He was originally interred at Black Rock Burial Ground, and most of the remains there, including Eaton's, were later moved to Buffalo's Forest Lawn Cemetery.[40][41]
