I have no seat for the B7100HST. I do have the 2-hole brackets that swivel on the rubber bushings so I can mount a flat base high-back like what is at Tractor Supply if I wanted. Reading through other posts on here talks about WHAT to buy...but no real opinions on what is more comfortable. It looks like the pan seat will keep you lower in the saddle (which is what I prefer being 6'1") but is your back dying after 2hrs of mowing? I have pan seats on other tractors and like but don't spend hours on them. I also see "OEM" style pan seats ranging from $100-$200+ from eBay, Amazon, Messick's etc. Are some cheaper quality that others? All inputs are appreciated...
