I demoed the 23/52 today. It seemed to cut well in thick grass. it sprayed the clippings at least two rows over. I cut on a very bumpy and hilly yard and lot and it was very smooth. That same place beats my walk behind to death, and i did it in half the time. The deck was a little un-even, but that could have been tire pressure or it just needed to be adjusted. I'm sure that is not a problem. I was also cutting my yard which is very healthy (thick) 2 week old bermuda (with rain every day). It went through that like nothing. I purposly let it go that long for the demo. it needs to be cut every 4-5 days. I do have a question? Any of you that have these how does it do mulching? I will probably just put a quick chute or something on there. I think if i get on i will probably get the 21/48. I have a price of 6300 with 0% for 36 months. I still have to demo the exmark, but i almost don't want to due to the better deal on the ferris and better dealer support. Let me hear your oppinions?
