I use a 20’ trailer for my B2650, which is dimensionally the same as an LX2610. If I often need my flail mower (similar size and shape as a tiller) and my grader scraper at the same time, and it fits perfect. I’ll back on with the grader, unhook it clear at the front, drive back off and hook on to the flail mower. Drive on forward, which balances my load really well, and leaves me about 8” of spare room on the deck.
And, HST for either of those machines. All. Day. Long…. They’re both great, but each is better at different things. If you’re more into mowing, go LX. If you’re more about the digging, dragging, and loader, the L wins.
