Loading the tires tonight with -20 WWF. Also put some louvers in the hood right above the DPF. Can’t hurt anything to let some trapped heat out of there. I also put in a 180 degree thermostat and replaced the green coolant with Peak Final Charge. Ive only mowed so far and am concerned about my hydraulic fluid temperature. Logging different things trying to figure out why but with infrared thermometer I’ve seen as high as 210 F at the rear remote. I’ve ordered hydro filters and I’m going to switch to Kubota Super UDT2 next week when they come in as well as change engine oil to Rotella T6 5W40.

Dusty, Those louvers look great and will probably help take heat away when the engine is not running. As an aircraft mechanic, I understand the importance of baffling directing airflow where it can be most efficient to cool engine parts. The engineers at Kioti probably designed the cowl and fan to remove heat from the DPF and direct it down past the firewall removing heat from the exhaust system post DPF. You may have just breached the levee. Could be that now the air flow is reduced and doesn't flow past the rear engine and can't cool the DPF as well?
Maybe you could do some experimenting by checking temps with louvers blocked and not. Would be a fun read here on TBN.
Nice tractor.

Premium lubricants like you have chosen are never a bad thing either.......:thumbsup:

I also saw high temps at rear remotes approaching 200. Was told it was normal operating temps?? I changed to a semi synthetic trans fluid and it seems to run a little smoother. Enjoy the new machine.

I've been running R6 Rotella since the 50-hour break-in oil change. Too much heat was never my problem. My problem has always been not enough heat. Hydro trans wise Kioti's own fluid is a hybrid between 20C and 20D, which is to say, just about everything works.

Interesting idea. FWIW, I noticed when mowing pasture grass this afternoon with my NX4510HC that the volume of airflow through the side grills on the hood is much greater on the left side, where the DPF is located. (Chaff builds up on the two left grills much more quickly than on the right side). Now I'm wondering if that's by design to concentrate airflow to the side and just below the DPF. :scratchchin:

I’d say just as likely the exhaust on that side hitting the ground is blowing the junk up getting it caught on the screen.
The DPF is well above the fan / fan shroud and most of the airflow is going down and not up.
I’m working through where the heat is coming from and so far I’m leaning on the cooling capacity for the hydraulics has everything stacked against it.
1. Very small cooler tucked in between the condenser and radiator. If the AC is running the only air the cooler is getting is 120F degrees plus.
2 Hard line out of the cooler is run directly along the exhaust.
3 High hydraulic flow rate coupled with lower overall oil capacity.

Pics of hard line and the dinky cooler.

MY thoughts exactly!

Same engineers who came up with the 3rd function valve I suppose. Restricting the flow with a couple of step downs between the power beyond on loader valve to the 3rd function then again from third valve to line that feeds the rear remotes and 3 point? Great heat generators.
