Double check the gear box fluid level, I gave a pump of grease to each zirc fitting, and checked the belt tension.
I did the same on my Funny Top 132.
You do know that the manual says to run it 15min lifted off the ground to run it in?
Only issue I had was this: the rear roller was mounted on the extensions, so for the initial run I moved it to the spot near the rear of the mower. Bad idea, first few feet the blades literally dug up the ground with the mower being level. No idea why that is, shouldn't be, it's not an in-ground implement. I had to tilt it way back with the top link to get an acceptable cut height. That, however, exposed a lot of the open front, which I deemed too dangerous.
I then re-installed the extensions to give it more height at the rear, which works well regarding cutting height. However, it seems that the extensions, which are a slight S-Shape to accommodate for the width of the casing, did not bend in enough. That resulted in the roller popping out of it's bearings within the first half hour or so. I fixed it by installing a washer between the case and the extensions, so they would come in more. That has worked well so far.
So if you mount the roller directly to the mower without the extensions, lower it to the ground, level it out and then see how far the blades are from the ground.
Also, I totally like the manual side-shift, but you need to make sure the mower is level (via top-link) if you want to move it, otherwise the weight of the mower is on the pins, making them impossible to remove (and you'd have to actually lift the mower up to move the side-shift).
