This size tire should't be very hard if it hasn't been on the rim for several years. Keep in mind the bead of the tire is what binds it to the rim and any damage to the bead lessens the gripping of the tire to the rim. What I an going to tell you is how I would do this. This by no means is the best way and remember advise is like tools in your tool box, if the wrench fits use it, if it doesn't then use something else.

Not to take anything for granted, jack up your tractor with a jack that can be raised and lowered easily and will support the tractor safely.
The beads can be broken two ways, either on the tractor or off lying on the ground. To break the bead on the tractor you need a helper and access between the tractor and rim to hold a bead breaker and strike it with a sledge, thus the helper. After letting the air out start with the inside bead first. Hold the bead breaker wedge so when striking it will work its way between the rim flange down to the flat of the rim. Then position the breaking wedge to drive the bead toward the center of the rim. Follow this in short distances around the rim untill it is loose all the way around. Repeat this process on the outside bead. When the tire beads are "broken" from the rim rotate the wheel untill the valve stem is at the top. starting here carefully work your tire tools under the bead on either side of the stem shile pushing the bottom of the tire towardthe center to allow it to move into the drop center of the wheel. Keep working your tire irons alternately untill the tire bead clears the rim. You can now remove the tube and start removing the other bead over the same side of the wheel. to facilitate holding the tire in the drop center area of the wheel, you can raise and lower your jack thus holding up on the tire when needed.

To reinstall, reverse the procedure bing sure your wheel has ben prepped and the bead lubricated with vegatable oil or a soap solution. Start with the inner bead and work it over the rim flange. Insert the tube into the tire and position to allow centering of the valve stem in the tire and wheel. Then partially inflate the tube to get out all the wrinkles and tube, then deflate. If needed the tube can be rubbed with silica or talic to help it level out inside the tire. Now deflate the tube untill it almost collapses, then rotate the wheel untill the valve stem is at the bottom. Start at the top with your tire irons and work the bead over the rim flange. Again you can raise and lower the jack to facilitate holding the tire beads in the drop center area of the wheel. Great care should be taken not to pinch the tube with your tire irons and that you finish at the valve stem. Otherwise you can tear the valve stem from the tube with the bead.

After the tire has been placed over the rim inflate it carefully. Check both sides of the tire to ensure the tube is not caught between the bead and the wheel. After you have inflated it all the bead areas should be flat against the rim flange. If not, deflate the tire completely and repeat as many times as necessary, and repositioning the tire as needed untill the bead seats. The maximum amount of air used to seat the bead should be noted on the tire itself. Be careful and use common sense. This information is given to you becaused you asked, I am no expert and do not recommend anyone try this if they are not savy with the physics and dynamics involved. This is hard work and can be dangerous to professionals!
