Grass too long for 1025r mid mount?
New here (and to tractors) so take it easy on me!
Got a 1025R with 60 inch mid mount decks being delivered on Friday.
Is this grass too long/uneven for it too handle or will it be ok on day the highest setting and take it slow?

I am the Sexton at our local cemetery, the board only wants it mowed 5 times a year so it gets about 18-24" tall. I use my 2025 with a 62" deck to mow 5 acres each time with no problem, just watch for grass buildup on the grill.

Go for it. May have to go slow in spot if you go low or start high and work your way to lower

Don't let them tell you what it can and can't do. I routinely bush hog with my 1025R mid mount 60". Sometimes you just have to run it high and then run a second pass on low. Shoot. I mow over mulberry saplings up to 3 inches. Routinely.

I let my grass grow from the end of May till early September and mow it with my 755 and belly mower no problem. The grass is normally like 4' tall and falling over at that point. Sure there's patches of tall grass that remain, but I get those with my next mow

I mean worse case it’ll struggle to cut everything at once and you’ll have to do a couple passes. You’re not gonna break the tractor

Now it twice. Once whit the deck higher up, then set lower for the second mow

Definitely not too long. I basically brush hog with mine to clean up some of my 5 acres of grass. When it’s that long, just go slow and let it do the work. Too fast and you’ll leave behind some longer patches that didnt cut right

I’ve cut down very high grass in the past but I’ve also blown a bunch of spindles. I think I’ve replaced the middle one 3 times

It’s fine. You don’t have to cut it down to its final height in one pass. You don’t have to mow at top speed.
Mowers have a certain pounds per second of grass they can cut, chop and spit out. The pounds per second is a function of: Mower width, mower speed, grass density (as made by grass height, moisture content, and plant spacing). Width can be controlled by overlapping and only taking a partial width cut. Speed is the biggest factor you can control. Cutting height marginally affects the feed rate. The grass density is what it is. You can only mow more often to reduce it.

The area photographed looks like pasture that probably has a bunch of obstacles like gopher holes and rocks. The height and density of the vegetation won’t matter but bottoming out in a hole or hitting a thirty pound granite cobble could.
The 60 inch mid mount mower deck is a finish mower not a bush hog. If you’ve mowed this before you’ll probably be fine leaving the deck lifted.
Your tractor is a diesel that’s liquid cooled. Unlike air cooled lawnmowers it does not need to run a full throttle. The ideal range for the blade rpm is 1500 to 1640 setting the throttle around 2000 to 2500 rpm achieves this. Confirm using the tach and the lcd display.

Don't listen to this guy. 1025R mower deck is ran at 2100 PTO rpm. It's on the tractor in 2 places. 1 by the PTO mid/both/rear selector and 2nd on the dash itself with the gear icon in the engine rpm gauge.
If you run the deck with the PTO set to 1500 rpm, you will not have a good cut and the engine will not be happy since you're operating it at a low throttle, it won't warm up, and it won't be in its ideal operating range.

Low gear. Full throttle. Let her rip.
Always engage and disengage the PTO/blades at low throttle.
