- XP 540 HD / 660 HD / 720 HD weighs 1,330 lbs (603.3 kg); V554X weighs 1,176 lbs (533.4 kg), a 154 lbs difference. Operating weight bears on trailer payload, ramps and soft turf. On its own it says nothing about build quality. What XP 540 HD / 660 HD / 720 HD's weight means for a trailer ›
- XP 540 HD / 660 HD / 720 HD has a 27 hp engine; V554X has a 24.5 hp engine, a 2.5 hp difference. Published horsepower is the maker's rating at a stated engine speed. It is a different measure from displacement, and two engines of equal rating can pull differently.
