Now that this 790 is starting to prove itself... I am thinking about adding some liquid ballast to the rear tires so Im now trying to figure out what I want to fill them with. Most all of the DIY people are using some form of washer fluid or RV antifreeze and water. I noticed the other day that the tires would spin super easy in loose gravel or dirt so I think adding some ballast to the rear tires will be worthwhile.
The rimgard charts have a 75% fill of the tires on this tractor (12.4-16) at around 250 lbs per tire with ~ 24 gallons of fluid. Rthat might be a bit much for this little thing with the lighter duty work it will be performing. Stepdad has a similar size JD wth a FEL and has his filled @ 50% with RV antifreeze and has been happy with the performance.
I guess my question for the group is would it be worth my time to add 12-15 gallons of washer fluid to each rear tire adding 100-120 lbs to each? I am thinking it would but have no rear world experience with it.
Thanks for any useful input.
