I've never had this issue with my Kubota B-21, the FEL simply works. I'm getting my new G3038H tomorrow and it will be interesting to test this out on that. It has a 4 in 1 that weighs in a "tad" more than the standard bucket so that might make a difference too. When/if we get some snow it will be interesting to see how it handles the blower. My B-21's dual pumps produce a total GPM that is 2 larger than the LS so we'll have to see.
I'm moving from 40 hilly mountain acres with a mile of private main road and probably three miles of internal roads, culverts, water falls, catch basins, etc to build and maintain to 2.5 acres of level pine/cedar/fir/oak forest so my LS will be in retirement mode compared to my trusty B. I simply cannot be without all the service a tractor gives me.
