Need to swap the battery on my L3400HST but I'm getting mixed info. Some charts say it takes a Group 24, others say 24F. Tractor's not here to measure (it's 60 miles away), and amazingly it's still on the original battery from when it was bought new back in 2007/08. It was cranking weak toward the end of last season, so it's on borrowed time. Before I make the trip, does anyone know for sure what group size fits the L3400 without hacking the tray? Don't want to haul the wrong one out there.
