A little progress update.
A few weeks ago, I tried using the case to cut grass and it died (walk/push of shame). Pulled the fuel line and nothing was coming out (yes there is gas in the tank and the vent isn't clogged.) Tried another pump - same issue, oil leaking down the side of the block and after a few minutes it stopped pumping (another walk/push of shame).
I found a blanking plug in my stuff and went shopping for an electric fuel pump. Found a nice one at NAPA. Runs great with the new pump. Cutting grass was going well until it chugged and died. Oops, out of gas. A splash of gas and was able to cut quite a bit of grass. Until it stopped again. Started, but wouldn't rev. Limped home, just above idle. The bolt holding the condenser came loose. Quick fix and back to cutting grass.
My son was out cutting grass and the deck belt failed. Found a source for a belt and pulled the deck covers off. The sheaves were a bit rusty so I used a bit of sandpaper and took off most of the roughness. I don't see any grease zerks.
A week later and time to cut grass again. As I learn how to run the controls (still getting bouts of whiplash), I really like this GT. Thanks to other members that have described some of the unnerving noises as normal. Squealing up a hill, grinding on the way down. Not to mention that my right toes are close to the melting point on of rubber (shoe soles).
Out cutting grass again and it's working great, until it just stopped. Another walk/push of shame back to the house. Turns out that a low-voltage wire broke off at the coil. Fixed that and back I'm back to work. Until it stopped again. The temporary wiring for the fuel pump (alligator clips) came off and the tractor stopped again. A quick re-clip and back to work.
Cut is really nice and clean looking. This is by far the fastest mower I've used. I don't mind that it doesn't have the hold-back valve. Just take it slow on the down-hills and engage the retard position.
Due to the high ride height, I feel more confident using Sears with loaded ags and wheel weights for cutting steeper slopes around the ditches.
