Cub Cadet's XT1 Enduro Series lawn tractors are mainstream choices for 1-2 acre properties, balancing comfort features with accessible service parts. A representative new price is based on Home Depot pricing for an XT1 Enduro LT 46 configuration, acknowledging that XT1 trims can range by engine and deck size.
If steering rack teeth are stripping, repair is often worthwhile when the rest of the tractor is sound: replacing the rack/pinion components and checking front axle bushings can restore safe control for well under the 40% threshold. Replacement becomes more attractive when steering failure is combined with deck vibration (spindles), transaxle wear, or significant frame/deck corrosion, because those stacked repairs can exceed the threshold quickly.
Safety matters here: excessive steering play can cause loss of control on slopes or near obstacles, so don't defer the fix.
