Rustyboy,
User jonesandjones has the regular Pro-Turn and I believe the suspension seat on his has the dampening isolators similar to the upgrade kit for the ZT HD. Hopefully he will respond and give you some feedback, otherwise I would suggest you send him a private message directly in case he isn't getting emails on this thread any longer. From what JJ said about the Harbor Freight jack it would do fine for changing blades, etc. I have the MoJack(the small EZ Lift model) and it also does a fine job(I used it to r & r my blades when I installed my mulch kit. I got an amazing deal on my 2012 Pro-Turn 100 XDZ(in the Fall, just before the dealer got the 2013 models in) and it has the full suspension seat(it has a VERY smooth ride). With the price increases over the last two years industry-wide I probably couldn't afford mine if I looked at a new one today(they are close to $8K.....almost $2k more than I paid OTD). Personally I think for mowing 1.5 acres(would take you maybe 45 minutes on a 48") the regular suspension seat would suffice. I hope JJ gives you the skinny on that!!! You won't regret buying a Gravely!!!!!
Thanks for your input. Yes, the brochure states that the Pro-Turn has an 'integrated suspension seat'. And I now see you have the full suspension seat, something I didn't know was available. Not sure how the suspension kit for the ZTHD compares to the Pro-Turn or your seat. All three seats look completely different. The cost of the suspension kit is $260 - the photo on the Gravely site in their accessory download section shows the kit and shows a knob that appears to adjust the two horizontal springs that fit within its frame. What is now puzzling to me is that knob - I assume the knob is to adjust the tension of the springs. I notice that you also have a knob on your seat; does the knob adjust the spring tension? Lastly, how would I send jonesandjones a PM as I don't see that choice anywhere? Thanks,
