I have the XR3037HC and very happily satisfied. I didn't really do enough with the tractor to warrant buying a 4040 so the 3037 is what I got. I bought mine this past Feb. It came with loader and a 7'6" snow pusher for around $27K incl sales tax. Pusher blade was about $1500.
No regrets here. Mainly bought for snow plowing so very little use in summer. Just turned 41 hours in 11 months. Now I have some additional attachments so summer use should increase. I did get the HST which is great for snow plowing and loader work. I'll never go back to gear again.
