Decisions, decisions

I have a 2019 Hustler FasTrak SDX 60" with Flex Forks added. It had been my brother's, but he passed away in 2023. I have been cutting the grass with it because my plan is to move back into the old family home, where he had resided. Right now I mow between 2 and 3 acres, but once I'm in the home, it will only be about 2 acres. I have been planting trees and I'll be planting more. I feel that this mower is too big for me as I am 5'4" and I will soon be 70 yrs young. I have been getting offers with this as a trade in, but I think that I could get more if I sold it out right. It's in average condition as I have gotten a few scrapes on the deck because my depth perception is a bit off. My mowing area is not totally flat. I'm thinking I would do better with a 48" deck. One place offered $2200 for a trade in and the other offered $3000. I was looking at a Bad Boy for the lower trade in and the second I was looking at a Hustler FasTrak SDX 48". In the area I live, it's Hustler vs Bad Boy vs Spartan, then there are also Toros, John Deere, Cub Cadets, Gravelys, Dixie, etc. I want something low maintenance-long lasting, with enough power to cut Zoysia grass, and can cut up and down small hills. I have two questions. How much is my present mower worth in this market (range)? What is my best option for a low maintenance-long lasting mower? My brother had a company come get this one and service it yearly and I did the same for last year. If it's not traded in or sold, I will do the same this year to maintain with upkeep.
