Hi wce,
there you go. Even though those are not a ball bearing wheel either, they are much lighter than the originals and that alone makes a difference. I have a steel FC mower with those on and it's easy to push from memory. I have a similar hi arch with the heavier nylon sleeve wheels and it also feels sluggish to push in grass just like I recall the Pace Premier felt.
If only I knew to swap the wheels!
