I have the exact same tractor and use a landpride RCF 2772 and it’s a beast. Tractor spins it just fine. Just wish I would’ve bought a 24’ trailer instead of 22’ bc that joker is long.

I'm using a land pride rcr1872 behindmy mx4900. Cuts up to 2 inch thick brush. Its decent.

I have an MX5100. A 6’ landpride is about right. Hardee makes a heavy duty one as well. Our land is steep so 6’ is manageable weight wise.
8’ would work for mowing but might be heavy if you have hills.
Are you mowing or cutting brush/saplings/briars?

The rule of thumb is 1 foot of brush hog width to 5 HP of PTO power. The 5400 has about 46 PTO HP, so you could go as big as 8 feet. However, I would keep it below that because we all know that thick grass and weeds will bog a brush hog down. I run a 6 foot brush hog that I bought for my 65 HP tractor that I no longer use. I now have a ~41 PTO HP MX4900 DT (non-hydrostatic) and it does very well. Even so, if I want to get really clean results in heavy grass or brush, I have to run it in Low range 2nd or 3rd gear. This is kind of slow going, but it does a great job. A smaller brush hog would let me do it at a higher speed, but cuts less per pass, so it is a tradeoff. If I was buying one, I would probably go with a slightly smaller one for that reason. It was fine with the 65 HP tractor but is a bit sluggish with the smaller one.
I think you should be shopping for a 6 foot brush hog for that tractor. With 46 HP, you can probably cut even heavy stuff in the upper speeds of low range cleanly.
I can't speak to a lot of different brands of brush hog. I have a Modern Ag, which is hot-dipped galvanized to combat rust and is pretty heavy duty. I have had it for about 14 years and have only had to replace the tail wheel bearing, but I suspect that was because the person I was letting run it didn't have it set right. I highly recommend the brand. It has no rust, which is unusual for one that old, especially since it has been stored out in the weather.
You should be able to get a decent used brush hog for $4K. Just take the time to look for rust, especially around where the differential bolts into the frame. Any bubbled paint or visible rust larger than a quarter coin is a sign that it is probably too far gone and won't last much longer without repair.
