For all around use, it's difficult to improve on the 2166. I just sold mine with much regret. The 48" deck was just a bit large for my rough, hilly lawn and it didn't have a grass catcher. The Toro ZT I'm now using does cut smoother and turns tighter on the flat, but the tractor's ability to handle sidehills will be sorely missed. The transaxle on the 2166 is a big 'un an makes the Toro undercarriage look like it came out of a kitchen blender. No chance the Toro will be doing the job as long as the CC.
