The pump is not working - either because you have fitted the new seals incorrectly or it hasn't been primed correctly.
Dismantle the pump again refit all the parts correctly and check the other seals in the process. Then check the fitting of the hydraulic pipes and prime the entire installation by forcing oil in it while rotating the pump and the wheel motors by hand. Do that for both position of the lever to make sure the regulator has also been filled with oil. Finally start the pump motor and shift the lever to forward and push the mower.

the belt tension could cause the mower to not pull on a hill you can pull on the belt and if it's flopping around also look at the belt for signs of oil oil leaking on the belt will also cause the belt to slip
