fwiw I still use my old manual shift Wheel Horses for everything, till/plow/grade/mowing so yes' everything. First WH I bought was a 1976 10hp, my other main WH tractor is a bit bigger is a 1988 14hp both have cast iron Kohlers. I'll take a used garden tractor over a new mower any day because it will outlast them by decades. They weren't built as throwaways then, you repair them and move on like farm tractors. Cast iron, not aluminum engines/trans.
More and more mower corps continue to follow "Planned Obsolescence" today forcing people into buying new mowers much sooner. Those HD or GT decals are a big scam so buyer beware.
If my old WH tractor engine bit the dust today I'd just rebuild/repair it and continue on. In 45yrs running these two units mowing 2.5 hilly acres, tilling gardens, towing etc.. my only non maintenance repairs have been a new carb on my 1988 and a carb kit on my 1976 model. Ethanol related issues got me. Neither burn/leak oil between changes.
Old post I know but still applies today. I can only suggest that anyone who has big hills or tows like myself to locate an old well cared for true garden tractor with manual shift & side shaft iron engine like a Wheel Horse, Cub, Deere etc. to do it with because the majority of todays hydro models will simply wear out causing you to spend, spend and spend again. They just don't make'm like they used too and they never will again but you can find them. Most true garden tractors for sale are due to death or owners buying a larger Kubota tractor so timing is everything but they exist, just buy the Kohler too.
I've watched a couple decades now as neighbors, friends and family repeat buying mowers time and time again as my old WH tractors continue to soldier on without fail.
Something these mower corps put in their shiny new paint that keeps drawing people back to buying their pretty junk every few hundred hours, idk but its certainly shameful.
Smaller flat areas 1/2 acre less, no towing most any of todays mowers should be fine. Hills/towing forget all about you get what you pay for, get the sticker number off the new mowers trans and do your homework "Before" you buy it not after.
Everyone's different and if towing you subtract trans/engine life? idk how much life, sorry?
Its estimated average mower with K46 trans life is 300hrs...TRUE!
Your wkly Mowing hours (2 hours)
x Your #Weeks you mow (4/5 times month)
x Your #Months per season (5 Months)
Average 50hrs Year
Multiply 50hrs times 6 yrs = 300 hrs...
Some weeks we mow twice, most only once so add a few, just an average anyway nothing in stone.
