Tire studs?

[Too many Kubotas]

Grooving tires takes a lot of time. I have only seen this in cases where a tire reseller wants to deepen the groove to make the tread depth deeper, not add new grooves, but the hand held tool isn't a fast option.

Grooving is fun, I think. Well, for the first 1/3 of the first tire.

I've done lots of it, primarily to create a more flexible contact patch.

I run chains front and back!

Chains? Aren't they normally referred to as bracelets in those sizes?

Beats walking, or shoveling!

You hate using them or installing them? Installing them is a little work, though it really isn't bad at all on a little machine like yours. Nothing like putting chains on a 6 ft high skidder tire. That's some work.

They're cheaper, but studs won't last anywhere near as long. A few seasons perhaps, with the efficacy going down each one. Set of chains should last essentially forever if you're not using the machine on a daily, commercial basis and if you take them off in the summer.

You can (and should) chain up all four tires unless you don't have clearance in the fenders for them.

We hear so many times how hard tire chains are to put on.
Use the right method and they are not bad at all. Just let the tires do the work.

You can also find this method on you tube and some chain venders websites.

That's similar instructions as my Aquiline chains came with.

If you put 'em on more than once ever 4-5 years you'd be a lot better at it.
If you notice that the boys in snow country that must put them on each winter are mostly the advisors on this topic.

You ever driven a tracked machine on ice?

About the same as watching a hog on ice.
