Hello everyone, first post here. I just completed the paper work for the only l2501 hst I could find in my state - NM. The tractor is in a crate and should be ready for pickup next week. One thing I failed to look at on the dt at the dealer was a seat adjustment. Do these seats have the ability to slide back and forth or are they fixed in one position? I got the the tractor with a 54" box blade and 48" rc. The dealer recommended these sized implements for optimal performance. Any thoughts?
