Because they’re meant to do landscaping type tasks, if you want something around same weight as 2032R then look up the L3301, that tractor is meant for more field work. Kubota gives you the option (BX, B, and LX) for a lighter weight setup if you want to do a lot of work on lawns which I appreciate, as my tractor spends a lot of time driving on my turf. If you want something with more weight look at L.I'm comparing the LX3310 with the JD 2032r. Anyone know why the Kubota weighs 500 lbs less than the JD?
