Be sure to clean the posts and the clamps with a wire brush.
If that doesn't work, test the new battery.
If battery is ok, check the wires where they go into the clamps, see that they are clean/not broken.
If all ok, check at the starter, make sure you have good ground as well. 75% of the time it's bad ground somewhere.
Good luck.

Dumb question, but have to ask. Did you put the cables on the right post??? Positive to positive and negative to negative....

There is no fuse between the battery and the starter solenoid that I am aware of. Do you know how to test the starter by crossing terminals? MAKE SURE TRACTOR IS IN NEUTRAL BEFORE YOU TRY IT. That will rule out a whole bunch of issues, then you can deal with switch or safety switches.
Make sure you know what you are doing before you try it though, if you're not sure, feel free to ask.
Good luck.

It may sound rediculous to you now that you have checked everything you can think of,.....BUT,...some batteries have to be filled and "charged" when brand new over the counter. (IF it's "that" kind of battery, that is usually done when you purchase it as part of the deal). Do you know this was done or do you have a way to test it to ensure the battery is "charged"? Put a test light across the terminals, .. should light up.
Next thing after establishing the battery is "good-to-go",.... (atgreen, above) gave you the best advice,....and it still stands: IF the battery is good, then it could be other things such as the starter etc,....BUT,..my guess is still with one of your CONNECTIONS. Remove your cables from the battery and run a rat-tail file or rolled up sandpaper, emerycloth or small wire brush made for it, through the cable ends till they are shiny and clean. Do the same with the terminal posts.
Remove, check, clean up the ground connection where the cable attaches to the frame or engine block, then tighten it down good and tight. Make a very carefull inspection of any and "ALL" connections from the battery to ground, to the starter etc. You likely know this, but the battery post connections must be very "tight" also.
If you were able to boost-start it before without a problem, then chances are good that your connections to, and from the ignition switch are okay. But just "think" of any and "ALL" things you did during this repair. USUALLY, if it worked before you started taking things apart,...chances are good that the problem lies with putting it back together.
Yes, I know you "think" you already did all this, but if it still won't crank, it has to be the "battery" or a "connection". NOTE: as Mr Green said, before you try testing the starter, make absolutely certain it's in NEUTRAL,....otherwise you will run over yourself!! Stay Safe!!
Try it,....good luck,

PTO lever(s) down?. Seat interlock free to move? If all this is OK, then try jumping it off a vehicle. My 1070 also had the same issue. Cables went bad at the ground. Solid, but corroded. The battery was never the actual problem.
