Who here uses mower jacks (more in terms of ZTR's)? Which brand are you using, and what did you pay for it? Are you happy with it? Do you feel they get in the way when you're trying to work underneath the deck? (sorta seem like they might) Do they raise the deck high enough for you? (sorta seems like they don't). Anyone built their own? I know the manufactured ones are kind of pricey (at least I feel they are). Thanks.
