Most everything I would've said has been said. One thing I'd add though is that the BH and FEL are not light weight and, in my opinion, should be removed for mowing to reduce the weight of the machine on the lawn. Not a big deal for your rough 2 acres but if the 1.5 is in nice shape, you don't want all that extra weight compacting the soil every time you mow.
And yes, the BH and FEL come off pretty fast. The BXpanded dolly is well worth the money to make the BH even easier and faster plus maneuverable while dismounted.
