I ended up purchasing the John Deere X350. 42 inch cut. Got the front grill guard. Upgraded the seat. Bought the bagger attachment (backordered). Did put the electric mulching kit on it.
Here's the funny part of it. I did it about a month ago. I had noticed that the old Yardman had a flat tire from over the winter. So I got the tire off and got it fixed at Fleet Farm. No big deal. I go to put the thing on, and it won't go on. I can't get it the extra half inch it needs to go back onto the base.
I called a few local mechanics that work on mowers. Nothing. They had no clue.
So, I ordered the Deere from Proven Power in Oconomowoc. When they delivered the mower, they took the old one.
The guy that dropped it off looked at my old mower, muttered something under his breathe and turned the wheel around and put it onto the mower. Told me I wasn't an idiot (which obviously wasn't true). He said that the valve stem went on the inside on some of the older mower models. Unreal.
That was the funny part. The cool part was, he spent over an hour with me, just going over the mower. Then he stayed while I got on it and used all the features.
I've used the thing twice so far and it is amazing. The first cut, well, the grass was really high. I cut probably 3.5 inches off of the grass down to 2.5 inches. I know I cut too much, but oh well. With that mulcher, there was no grass clippings discharged into the grass. It was all mulched up. Amazing.
