You need a garden tractor. If buying new that would be the X500 series or the X700 series.
There are also lots of used older machines that are still great. 240, 245, 260, 265, 285, 320, 325, 335, 345, GX series and GT series are all comparable to the X500 series which will include X500, X520, X530, X540, X570, X580, X590 and there are also 4 wheel steer versions with a 4 for the last number (ex. X534) which I'm personally not a fan of.
Then there are the heavy duty garden tractors. 425, 445, 455, X465, X475, X485, X495, X700, X710, X720, X730, X740, X750.
The 4wd versions would be X575, X585, X595, X728, X738, X748, X758.
The 4 wheel steer versions of the X700 series will end with 4. (ex. X734)
All wheel drive with all wheel steer will end with 9. (ex. X739)
