anyone have any ideas to convert the sears 3 point hitch to a powered lift? Thinking of using electric actuator, seems simplest...

What would I need to do, to convert it to power lift? What would I need for material?

Need to see what you are working on! I have a 108 that I am close to making hydraulic lift!

I used a power steering pump, a valve and a small cylinder. All suff  I had on hand. Works great and lifts a lot of weight. 

An electric actuator would work also. Had a Simplicity with electric lift and it worked really well. Nice thing about electric is you can lift the implement without the engine running and when starting in cold weather it isn't putting any load on the engine like a hydraulic pump does.

What kind of power steering pump ?

GM power steering pumps work good for these!

Boughten lifts have a spring or other movement mechanism to allow a little play in lift, so not to damage it. Sears has those now available and maybe you can go to thee parts site and see what is involved with mounting and copy.  You will need good power wire, not too thin, and a switch that is momentary contact with off in middle so it operates then is in N when you release. No toggle switches then.  What's wrong with the good old hand lever? Those can be bent, added too, or whatever to make them clear fenders/seats and such w/out changing anything else on the hitch. If such thing as you can't lift it that way, then maybe the implement you are trying to use is too much for the tractor.  I think electrics are sort of limited on the weight they can lift too.

Why put an light duty electric 12 V winch on the tractor to do the lifting.  Have one from HF on the back of a G16XL, cable end attached to the tractor frame and run through a pulley on the hitch.  Works good but have to watch so not to lift it to high.  Working on a horn alarm system now for that.

Nothing is wrong with the hand lever... the guy operating has to put some effort to it, so he decided to work smarter not harder...

That's what I use, one for a Johnny bucket type front end loader, and one for lifting implements on the back.  All run off of a car battery on the back.

That's true but I happened to have a Nissan pump on hand so that's what I used. I was using the hand lift but when using a rear mounted gas powered tiller that's a lot of weight. Now all I do is lift a small lever and up it comes. 

 

Why not put an light duty electric 12 V winch on the tractor to do the lifting.  

 

This is how I raise and lower the 4 foot snow blower on the Kubota and it works good. another very viable option.

Sears made a 12-volt actuated three point.

chieffan...Working on a horn alarm system now for that...

you could use a small switch with a relay, basically like the clutch switch, (NC - normally closed), to de-energize your power circuit, makes it "automatic" then, unless you just want the BEEEEPPPP...
don't use a seat safety, (NO - normally open), do-able, but more complicated to wire,
AND, don't use a starter solenoid as the relay, they're NOT meant for 100% duty cycle, will burn-up pretty quick
 
 
I like using a winch, simple, quick, easy, 
AND, if you find it pulls "tooo fassttt" - you can just add a snatch-block, cuts the take-up speed in half with 1, or use 2 and really SLOOWWW it down...
 
the nice thing about using a winch is the $$$price$$$, 
check 'em out at harbor freight, versus an electric actuator, 
priced a 1000# actuator, 'bout fell out of my chair,  :D
think I paid about $50 for 2500# winch, 
 
but if you already have an actuator, by all means, use that
or if like Cvans and you have some hydraulic parts, then use them
 
many have done a project like this here on the forum, a quich search will bring up a bunch of ideas
