Flat Free Front Tires on ZTR

I'm looking for some advice on the pros and cons of switching to flat free front caster wheels on my 7-year-old Gizmow 61" ZTR, which I use for both lawns and rough work. The mower has been remarkably resistant to my abuse, it does a nice job mulching grass, and it is very stable when mowing slopes. I do have fairly frequent flats on the front casters when I do really rough work, such as mowing the briars and small saplings on the back side of my dam every year or two. I have been thinking about replacing the front caster wheels with flat-free tires such as Marathon 13x5.0-6, which are filled with solid polyurethane. The owner's manual specifically advises against foam filled tires, which it says may cause failures to the hydro drive system. I assume it is referring primarily to the rear wheels, and I don't think that voiding the warranty is a big deal on this old machine. :)

Any opinions on the tradeoffs in replacing the wheels?

The only Con, is the up front cost. The Pros, they work. No down time to run off and get a flat fixed. No loss of production time. Less aggravation. Peace of mind.

If you take care of them, they will out last your Gizmo Thumbs Up

I have them on my ZTR and my stander. I hate them. They ride a little rougher than pneumatic tires and it’s almost impossible not to tear the turf with them since they are a little more flat than pneumatic tires. I’m going to switch mine over to pneumatic shortly.

The pro is not having 2 tires to monitor pressure or have flats on. No other pro that I can think of.

I foamed the fronts on mine. It cost me about $80 for the pair. You’ll also loose the use of the wheels for 3 days which is why I did mine back in February. I cut one last week so I’m already time ahead with that move. I never found a generic solid tire with good bearings and Tweels are nearly $500 for the front pair.

I don’t notice much difference having the fronts foamed. And that’s a sacrifice I’ll give to end the never ending headaches with them. I wouldn’t advise foaming the back tires.

Front tweels are pricey but they are closer to the ride of a pneumatic with no worries of flats. And they come with very high quality sealed bearings.
