Ive used a 52" sentar and a 32" stander. looking at the rh's.. they are just smaller framed versions of the sentars. being able to stand on a sentar is nice on occasion, but its not comfortable like standing on a stander.... so looking at the rh standers, im thinking that its like standing on my sentar... are their any differences whatsoever on the sentar sport and the stander rh besides the saddle seat?? imo, i would buy the sport sentar over the stander rh... it would be worth a little extra for the seat. they have the same hydrolics/mowing speed, etc. i believe. also what is the length of the 36" stander rh compared to the regular 36stander??? anyone that has made the switch to the rh, and has experience with the regular models, please comment. thanx.
