I've got a 4 year old Polaris 280
It's driveshaft seems to jam after the back up valve cycles
If I manually turn the wheels and unjam them it will work for a few minutes then the wheels will stop moving and jam again after the valve cycles. Sometimes j cam get through a few cycles of the back up valve
My wheel rotation is 27-28, seem to be having a hard time getting it faster. Pump is running well, in line filter is clear

Thanks for any help or ideas. Next step may be a rebuild kit

Found my issue -- apparently little pebbles had gotten stuck in the teeth of the plastic drive cogs and was jamming the wheels. I gave the cogs a thorough cleaning (i.e., pried the pebbles out with a small flathead screwdriver), put him back together, and all is working fine now.

I wanted to follow up with this.
I removed my 280 and pulled it all apart to inspect it.
The bearings on 2 wheels were bad.
Replaced the bearings and it ran well again.
