I don't think so. I used an 800 lb. ballast barrel on my 26HP. but my tractor 3 Pt. cat 1 is rated for about a 2200 lb. lift. If you have the owners manual it should give you a hint of what to use as rear ballast.

not sure what kind of tractor you have, but the book from my old JD870 (28 HP) lists the 3 point hitch capacity at 1880 # @ 24" behing the lift link.

I doubt 800 lbs is too much weight for your 3PH, but don't you have an operator's manual for the tractor? If so, the weight capacity should be in there (probably the specifications section).

Here's what I don't get: My tractor lists the maximum lifting force at the lift points of over 2100 lbs. At 2 feet behind the lift point, the lifting force is almost 1700 lbs. Now here's where they lose me: There is a section in the book called "implement limitations" where they list the maximum weight of various implements which can be put on the lower links. They are all like 500-550 lbs. What's up with that? Why can my implement only weigh 1/4 of the lifting capacity? Am I missing something?
I can tell you that my tiller is 700 lbs. and there is no problem with that. I know it's heavy, but the tractor doesn't flinch and handles it just fine. I've always wondered this, so perhaps this discussion can shed some light on it for me.

Just physics, most implements are going to stick out more than 2 feet. your tiller not as far as say a brush hog. The farther an implement sticks out the rear, the greater the leverage and weight put on the lift. So the capacity/rating would be lower.
Wish I could make a more coherent English statement. :ashamed:

It's because things like rotary cutters are so long, they are way out past the 24" lift capacity spec vs. your tiller which is probably at about the 24" lift spec. The further past the 24" mark the capacity decreases rapidly.

Its bouncing forces. It will lift 17-1800, but hit a bump while lifted and the force goes waaa-y beyond that and it could break the internal rocker arm. If you go much above their 550 guideline just drive carefully when lifted and youll be fine.

I completely understand the part about the force dropping the farther out you go, but at 24" past the lift points it says it has a 1700 lb lift capacity. The center of gravity of the tiller is probably about 24" and knowing that most tillers sit much closer than say a disc or rotary mower, it still says max weight for a tiller is 550 lbs. - same as for the much longer implements. Seems a bit on the conservative side if you ask me - I'm sure it's a case of CYA. The bouncing force is something that I'm well aware of, and is why I take it real easy with that heavy tiller - it's my heaviest implement, and the only thing that'll make the sidewalls give a little. The backhoe may be heavier, but on the subframe I don't really give it too much worry.
