Won’t move in Sand, but Fine on Road

2006 Polaris Predator 90

My son and I were recently out riding when we started driving through some loose sand. We had been riding through water, and hard gravel, black top etc.

Then he had problems getting the machine to go through sand if he stopped his forward motion. I had to tow him through the sand, but once we got back on the road, the bike drove fine. Later back at the truck I noticed that if I put a barrier in front of the wheels to form resistance, the bike tires wouldn’t move. I felt a LITTLE torque like the transmission was trying to move, but the bike wouldn’t go forward no matter how much throttle I gave it.

If I removed the resistance, the bike would move just fine. He rode the rest of the day, but always had issues when he stopped his forward momentum in sand.

Any thoughts? Could it be the transmission? Is this something to do with the CVT? Could the water have affected it?

Thanks for any input in advance.
