I have two tractors and two zero turn mowers. I never remove the backhoe from my
B26, it is strictly a TLB. My LS is usually just used for soil tillage, bush hogging duties but occasionally gets to move some heavy loads with the FEL. The FEL has never been off as it is just too handy to have in place. I don't have any tight spots to worry about clearances so it isn't an issue to have it on even with the extra weight. My mowers are a Ferris IS700Z which is my dry land mower. I get out my Craftsman 6000 with the bar lug tires to mow around my ponds and any other slippery areas. The only issue with a ZTR is that if you get into a slippery area especially on a slope, you are not getting out as you will just slide deeper into it. This spring has been the worst for mowing because of all the rain, but with the bar lug tires, I have only been stuck about half a dozen times trying to mow my swamp area. My Kubota RTV 900 gets them out really easy though.
My only issue is that the Craftsman goes into the garage first so I have to move the Ferris out first in order to use it. One never has enough storage space or large enough buildings.
