John Deere Rotary Hoe question

I just finished working on a John Deere Number 7 rotary hoe some of the hoe wheels are stuck to the shaft just wondering where they are such a loose fit normally if using it will free them up. Just don't want to disassemble if I do not need to

I don't think they will ever break loose on their own. We had a hoe that was froze up and used heat ,penetrant, 4 foot cheater pipes and much muscle.
 
That No. 7 is not a model for that how, have no idea where you got it. And stuck wheels will not hurt anything. One wheel had a cotter in to keep axle turning and not to turn in the wheels. And I hated those style hoe wheels, worthless. Heavier hoe had 14 teeth per wheel and lighter one 12 teeth per wheel. Got rid of by JD hoe and got a Ford and between day and night better.
 
O.K. Looks like maybe it is a 14 series hoe, saw a picture of one and they had it labeled No7 so a series 14 421 or 422 sound right????
 
Never heard of a 421 or 422. Those could be new style hoes that I know nothing about. Mine was a 4 section drag type. And I could not add enough weight to get it to penetrate the soil. If you went over the same area twice you might have gotten a half of a job. Same thing with an IHC or McCormick hoe. The model was determined by the size of the wheel and not by width of unit. The 14 was avaible in different section widths of 2 section, 3 section, 4 section as a 3 point hitch or a pull type with a 6 section in a pull type, Somebody probably just looked at the width and called it a model 7 as a 2 section is a 7' wide unit as width for hoeing 2 rows in either 38" or 40" rows. Narrower rows would allow a bit more overlap. Unless the teeth are still like new with the full curve on the end with the spoon completely intact and not wore off as most are it will be not going to penetrate the soil, those rod type of teeth do not work in clay ground. I had to go to a hoe with angle iron type of teeth to get a hoe to work.
 
TBA the style hoe he is picturing does not use individual wheel bearings. If you look close you can tell this one has long pipes that run through the hoe wheels and the bearing. It is more like how a disk is made. Advantage it they have fewer bearings. Disadvantage is they do not conform to uneven ground. So parts of the hoe do not always touch.

Yes.

Take a look at the diagram below.

Note the plain wheel (Key 13) and bushing (Key 16).

Apply you favorite penetrate between all eight bushings and six plain wheels.

The plain wheels are designed to rotate easily by hand.

Hope this helps and enjoy your No. 7 rotary hoe.

Did you attempt to locate a parts catalog for a #7 rotary hoe?

I couldn't locate a JD parts catalog for a model #7 but I located this 3pt hitch schematic that resembles OP's rotary hoe.
