The side screens are more forgiving than the one directly in front of the radiator. The side screens can get really nasty and you won't notice the engine temp rise much, but if the one in front of the radiator clogs up, you'll see your temp gauge rise, and the tranny will run hotter, too. Whenever I remove the side screens to clean them, I always check the radiator screen too. I frequently wipe the side screens with my hands while mowing, but thoroughly clean them whenever I shut down, or when I see my temp gauge higher than usual. When you clean the radiator and oil cooler fins, blow from the fan side towards the rear of the tractor, since most of the junk gets stuck on the back side. I sometimes use a water hose and spray head and it does a good job as well.
Does the temp gauge look right for warmed up but just at a high idle with no load on it and about 70 degrees out? Where should I expect it if its hot and I've been mowing for a while?
My gauge usually runs in the first third of the green area until outside temps get into the upper 80's, then it runs in the middle third. If it's in the low to mid 90's, it may run in the last third just before the red zone. Up to a point, a diesel's efficiency increases as the engine heats up. I wouldn't worry about running it in the middle third of the gauge most of the time, but once you get into the last third, slow down a bit, or take breaks.
The manual never says anything about needing to change the MFWD oil only keeping it topped off? Is this right or did I miss something?
I have almost 1500 hours on my X748, and the front axle lube (mine is MFWD) looks new, almost. Same goes for my deck's gearbox. I just keep the levels at the correct place. On the gearbox, remove the side plug and fill until it starts running out the hole, then replace the plug (with the deck in operating position).
The dealer gave me SD Polyurea Grease. Is this appropriate for all points on the machine and mower?
Yes, wherever there is a grease zerk. I also use it on the balls of my 3-point hitch.
The deck belt on the mower is black but the one I got from the dealer is white. I looked up the part number M163991 and it appears right. Did they change materials at some point or maybe the PO just used another belt? There is no need to change it right now just curious.
My new one is the same way (white, where the previous ones were black). It also had a different part number, but otherwise it's identical. I think it 's a matter of where they source the belts.
Are there any service frequencies in the manual you think are too long or any items that should be on the list that aren't?
If you maintain the tractor by the manual, you'll be fine.
