My tractor has a lift capacity of 1389 at 24" and 1900 at the lift ends. I bought a power rake that was about 1300 lbs. The tractor handled it just fine but even with the loader felt a little unstable. My biggest fear was hitting a pothole and cracking the tractor in half with the rake in the air.
Ultimately I had little use for it and sold it this year. But if I were regularly using a heavy implement like that, I want a bigger tractor. Like something with 2000lbs+ lifting capacity.

Thanks, I have a NTD that is 1000# (empty) manufacturer recommends 1500# lift capacity, and I have to use it on some rolling hills and drive up a steep trail to get to one of my fields. I was a little concerned about stability and doing damage to my lift arms due to bouncing.

While lift spec may be 1,500 pounds, real life may be 1,3450 - 1,400 pounds on a high engine hour machine.
On even a slight slope your tractor front wheels may lift off the ground initiating a rollover due to too much rear weight.

What is the implement and what does it actually weigh? I dont put much stock in implement MFG's "suggestions". They are usually ultra-conservative for the CYA factor.

First thing I'd want to know is how heavy is everything forward of the rear axle?
If I recall/understand correctly the lift rating of a tractor 3pt is measured with the front of the tractor chained to the ground so it's direct comparison of the hydraulic lifting capacity between tractors. ....so not exactly real world useful, but then not all measures made for the sake of comparisons are based on real-world use cases.
So I'd be more inclined to pay need to the tractor manufacturer's recommended implement weights than I would a implement manufacturer's recommendations ....though even the tractor manufacturer's recommendations can be a bit conservative since they are likely based upon the worst case tractor configuration (e.g. no loader or front weights).
Though whichever recommendations are looked at it's probably wise to be cautious about exceeding the recommendations given the manufacturer's aren't always clear on why their recommendation is their recommendation .....

I am (maybe wrongfully) assuming this is the 50 hp 5500 pound tractor in the OP's profile?

Yeah, I can understand that assumption I was just a bit thrown off since the marketing brochure number for my tractor lists ~2600lbs lifting capacity, and the manual says 3750lbs at ends and 2650lbs at 24" behind ...and yet the implement recommendations in the tractor manual generally top out around 1/3 that weight for short implements (880lbs for a box blade) and decrease the longer the expected implement length.
I have used a 84" 1000lb 3pt disc harrow (manual recommends max 770lb 72" wide for pull type) with that tractor so I know the recommendations can be low, though I can also say it's definitely noticeable when it swings/shifts (while lifted) during a turn (and that's with full set of rear wheel weights and the heavier loader option for the tractor). Sort of feels like it's starting to cross a bit into the tail wagging the dog scenario even though the front doesn't feel light.
So it may be an older tractor with lower pressure hydraulics (and more realistic 3pt lift capacities identified) that has a wider/heavier frame, but I figure the simplest thing would just seem to ignore the lift weights and consider how much weight is forward of the rear axle and the overall total weight/size of the lifting tractor. .....at least if it's an implement that will be completely lifted/carried by the tractor.
