I don't have a loader on the 4400, my 6400 handles those jobs. The 4400 has a 60" MMM. When I bought the 4400 I intended to use it to pull a New Holland hay rake but I have upgraded to a large rake and I use the 6400 for all my hay duties.
The 4400 is used for mowing, post hole digging and putting out fertilizer with a 3pt mounted spreader, but mainly for finish mowing. It's really too large for finish mowing. A 2520 could do those jobs but I'm still on the fence about whether the ZTR would meet my needs better.
