Wow. It was a lot of "work" to decide. I have the 7308 loader and a borrowed 5 ft brush hog.
A lot of things went into the decision. Biggest was probably dealer relations. This is my first tractor of any type other than the lawn rag (MTD). I think I got a pretty fair deal. $15500 OTD. I saw on one of the posts buried here something about the 29 being a "turned up" 25. They both use exactly the same engine as far as I can tell. Same comp ratio, displacement, etc. except the 29 is run 200 rpm higher.
I REALLY like the visibility from the seat. Kubota and JD had square hood making forward visibility difficult. I mow 5 acres of trees and the NH hood/forward vis is really great.
I also like the hydro pedal setup on the NH. Even the wife likes to drive it, very easy.
I was kinda hung up on the 25 hp rating vs the 29 but can say I am extremely surprised by the response of the 25. Cut 3.5 acres of overgrown field that had not been farmed for years. Small trees, heavy brush, high weeds. No problem!
Was seriously considering Kubota 2710 with it's loader, but the NH was more "finished". The 2910 was too much $. Also the orange dealer was very firm on pricing, even with the current rebates I would have paid 1.5 k more for it. NH has better ergos, visibility, etc.
I have heard of the 24 due out, but have not seen any pics even.
Take another look at the 25D. If you can get a deal I don't think you would be pleased.
