The 7510 mostly mows and pulls a trailer I use around the property for a variety of things. It also carries my chainsaw and machete. The 1754 will shear some of the mowing starting next season. Currently I'm using the Massey to remove stumps, dig up and move large rocks, and haul the heaver loads that the 7510 can't. I will work both of them year round. Fall and winter are really busy for me, lots of cleaning up and clearing out to do.
