Clubairth,
My apologies, I forgot about the 3100s. I did love how they post 7 mph as top land speed although it should state 8 mph with a 3100 and 22" rear tires.
The engine guard I also forgot about as I have the RSD60 with the better solid guard. The 'vented' guard allows them to utilize the metal for the new double sided anti-scalp mounts. lol
There is a different hydro brace as well that attached not only in the front it also runs all the way to the rear wheel motor bolts as well. Seems it may be a good upgrade as well.
The difference in the deck which is the same deck with the addition of double anti-scalp mounts instead of single side mounts as well as adding the rubber scraper on the left side. The deck has remained the same. Same lift points, mounting points, depth, blade walls, etc. other than the discharge port has the open SDX as before and in the event you remove the enforcement bar and add the over top enforcement bar.
I do not like the round foot lift at all.
As far as the grand, if you chose to add 3100s to your RSD, you'd pay at least 650 each side. The guard would set you back a bill, the upgrade seat would set you back 350 bucks. I'd say a grand is still a bit high, but then, upgrading isn't free.
If you get it, my bet is you'd love it.
