900 RTV won't go good in mud/up grades in woods.

The work tires look like they would fill up with mud easily I thought you mentioned the one slope was not that muddy. Wondering if your tires may be over inflated, just a thought. Another thing to try is to run the tire pressure lower in mud on my motorcycle when I ride off road I lower the tire pressure and get noticeably better traction. We once went out in the sand dunes in a rented jeep if you didn't lower the tire pressure it didn't go through much.

I've had my RTV for a couple years now, a 2006 camo'd Worksite model. One of the first things I did to it was replace the Craptyle 489 tires with ITP Blackwater Evolutions just like Ovrszed did.

I believe the standard tires on a RTV (at least my model) is 25-10-12. I got all four tires in 26-12-12 so I could use the same wheels. Given how well it fits on my RTV, I believe I could have gone to 27-12-12. I got mine from AllTerrain Online out of TX; Robin the owner was very helpful. Excellent prices and excellent service. I had them shipped to my local tire company and had them install them. ATV Tires, Wheels, Winches & UTV Accessories - All Terrain Online

I live on a hill, both front and back of my property. I don't believe my 4WD works on my RTV, so I'm running around always in 2WD. I'll take my RTV in 2WD I won't take my Kubota L4330 in 4WD. Having said that, I don't typically take my RTV (or tractor) up and down my hills when it's wet and I don't have mud to deal with.

ETA: If you replace your tires on your RTV, do not use ATV-type constructed tires, they are not heavy-duty enough IMO. For the heavy RTV, you really need a 6- or 8-ply tire for it. The ITP BW Evolutions are 8 ply and have one of the heaviest weight ratings I could find.

Pics of my RTV and it's tires, note the hill in the background, I own it all the way to the bottom.
