I'm still researching the purchase of my first ZTR. I've finally begun the demo-ing phase and this is a lot more fun than just reading! My question on the Hustlers deals with the spindles. I don't think there are grease zerks on the spindles, but the literature I have states that the spindles need greasing once per year. This breaks off into a couple questions at this point. 1. I will be using this to mow my personal 2 acre lot and that is all. Should I still grease them once per year, or is that for more commercial use only (like 200 hours a year or something)? 2. What is the procedure to grease them if there are no zerks? Is it a pain to assemble and disassemble the spindles? I could be way off, and maybe there are zerks....I haven't spent enough time looking at the units in person yet...so if I'm wrong I apologize for the stupid questions! Thanks!
