Great A/C but no heat.

Oh and I’ve never seen a coolant leak under the tractor or in the oil.

Sounds to me like your blend valve needs adjustment.

It’s now giving heat. I’m thinking it was something with that radiator cap. I kind of messed with the seals and spring and now its pressurized. Sounds like a new cap in my future.

Ya, id swap it right away. To prevent engine damage

A good possibility the the cap was not securely fastened to the second stop, which would not pressurize the system.

My Kioti ck3510 chse has freezing cold a/c but now that fall it here I now realize there’s no heat. I turn it to hot or cold and it feels like outside air. Does anyone know where to start? With only 650 hours I’d doubt its a heater core but don’t really know how the system operates being that the air comes out of the roof unlike a car.

The blend air door is controlled by a cable. I had the cable slip when my cab top got infested by mice. While there shove steel wool down the A, B, and C pillars for mouse prevention.

That’s initially what I was thinking but before removing it I tried pushing it down while tightening and it was on correctly. I guess everything eventually fails.

I’m surprised you didn't see/smell coolant after running it a while.

 

[homedad]

Never smelled coolant. I was out at this property yesterday enjoying the snow. I just got an alert that my radiator cap has finally arrived but its back home. Anyway I ran this tractor for about 45 minutes and it barely got off cold on the gauge. I'm now thinking the previous owner removed the thermostat or it's stuck open.

There is a cable connected to the temp control. On my NX it fell off once. I popped the top off hooked the cable end back up and safety wired it in place. No problems since that time.
