    Shoot, sorry, forgot to address this part of your question.

    I can't, in good conscience, even throw out a number. Too little and it will be ineffective, too much and it could be really bad. You could end up with the front end too light and go over backwards.

    How about I teach you to fish instead...

    But first, let me throw in my favorite disclaimer... THIS IS ONLY MY OPINION!

    ZTR's tend to handle best when the weight bias is 18%-20% front and 82%-80% rear. Just remove vertical CofG from the equation because they are all similar enough for what we are talking about. Stray just a little from these numbers and the handling degrades quickly.

    It is also best to keep the weight as close to the center of rotation (the rear wheels) as possible. Read this if you're wondering why...


    Good luck Jimmy.

    thank you gotcha. ya i will experiment with the weight then. my model is a Z3815. how/where would you reccomend adding the weight? some kind of wheel weights?

    besides handling, how would you review this machine? as far as cut quality? I think its alright. the deck pitch is very hard to adjust and get in right. the way they designed the adjustment system is crazy. I got the machine for a really good price with low hours. If i could do it over again I do not think I would buy this machine again

    I haven't seen anyone say this yet... but I had terrible issues with my Dixie Chopper 72s doing this. The trick I found was to first turn right or left after you complete your pass, then instead of doing a zero turn and destroying the lawn I push one handle forward and one backward so both back wheels continue moving and it takes you right into your next pass. This is the secret. Since I learned this I have very rarely caused yard damage. Best of luck and God Bless,

    You mentioned square casters. Ive had one machine with those and never will again. Horrible in softer turf. Never have any issues with rounded casters.

    Yes Yes Yes, 3pt turn.

    Sorta off topic but as for the ZTR vs Stander war, this issue is one thing I love about a stander is being able to look down and literally watch both tires while in the middle of a turn.

    Plus one! - I always felt like it was kind of a rookie move to have to look down and watch the wheels as I’m turning, but I do it quite often, not all the time, but whenever I’m in a confined area or approaching the end of a stripe at a strange angle. I also watch the front casters to make sure that they don’t make a snap 180 turn and leave a mark.

    you could be turning using one lever instead of both. I mean when you go to turn, say rt, pull rt lever a little and push lft lever a little.

    Yep...that's the biggest thing. Make slow stops and starts especially with touchy sticks. I have tons of practice, thousands of hours on ztr's, and I still tear up spots from time to time ESPECIALLY when grass is wet. Spinning tires is as bad as pivoting on weak rooted lawns.

    Yes...make sure to try and keep them from pivoting especially if they are ribbed tires. I do wide 3 point turns making sure the front tires are rolling when making my 3 point turns.
