Newbie questions

Ok, now on to implements. I know even less about implements than about tractors, BUT, I'd like to get some to do some basic chores around the home, such as getting a small garden ready for the wife. What implements would be good basic ones to consider? Here are the ones I think would be best, but am interested in other's thoughts on my list.

Bush hog - pretty obvious why that would be helpful
Box scrapper (to keep the gravel driveway in repair)
I already have a corrigator (cultivator?). I was told it was a corrigator, but a friend said it was a cultivator...basically a bar, with about six heavy bars with chisel type (v-shaped) diggers at the end. It sure does a good job of breaking up the soil, but nothing "fine tuned" about it.

I'd like to be able to turn up the soil, break up the clods, and then create furrows with raised beds in some cases, and to simply go from rough undisturbed soil, to a nice smooth level ground (such as if putting in a new yard). Those are the two goals I have...what implements would be most appropriate, and why?

The tractor has a 3-point hitch (converted I guess from the snap-point hitch).

Also thinking about a post-hole digger, and front end loader (trip bucket would be ok), and perhaps a roto-tiller. Since my tractor is older, what is the likelihood that new implements will be compatible with my tractor? What do I need to watch for/watch out for to ensure compatibility? I've seen the term category 1 referred to...what does that mean, and what "category" hitch would I have? Long post, thanks for sticking with me, and thanks in advance for any advice.

anyhow, cat 1 is the oldest, standard size for all smaller tractors. The pins get bigger, & the arms get wider apart as the hp of the tractor goes up.

Many implements are designed for both cat 1 & cat hookups.

You will have a cat 1 3pt hitch on that size tractor, but as it is converted, it may have not exactly 'normal' geomety. Your lower arms might be extra long, or go higher or not as high or otherwise be outside of 'nomal'. (Tho ther is no perfect 'normal' set of numbers for this....)

So you have to pay attention that pto shafts aren't too long or too short for you, or that you don't bend or bust the pto when you lift the implement all the way up, or that the knuckles bend too far & chatter if all the way up or all the way down....

A post hole digger is especially particular about all this geometry stuff, as they don't use a top link exactly - the main frame goes to the top link area and becomes a 'sissors lift' of sorts. If your 3pt is very much out of the ordinary, a phd can be just wrong on there.

But, don't let me scare you. Just something to watch for. Likely all will be fine.
