Mine has a few zerks, i.e. on the ball joints, tie rods and drag link.
There is another one on the steering shaft that is WAY up near the top. Difficult to see without a flashlight. Keep that one lubed and it'll steer easier for sure. I also lube the rear springs to keep them from squeaking. The lever that switching from forward t reverse gets hard to turn, so I do shoot some liquid lube like Dry Lube on it.
Main maintenance thing I'd suggest is to keep those batteries in near full of water. They're $100 each minimum but will last easily 7 years if you do regular maintenance. I have to charge up the batteries, usually at 1/2 reading, about once every couple of weeks, and check the battery water about once every quarter.
Other than a 15 minute task, just get in and go. No muss, no fuss.
