One concern was , I had wanted turf but dealer said they weren't recommend for the backhoe use
I hope you misunderstood him, because if he actually said that, he's incompetent, in my opinion.
Who exactly, doesn't "recommend them for backhoe use"? MF sells TLB's with turf's on them, so it must not be them he was referring to.
These tractors were designed as "estate tractors". They are meant to maintain a homeowners property.
Most homeowners have grass. It you have grass, most of the time, turf tires are best for driving on it.
Now, as I said, if you want to play in the mud a lot, turfs are not ideal. But, for anything else, I don't think you can bet them. And, you can always chain them up, if you need to play in the mud.
They will, just like a car tire, load up with mud, and slip, if the mud is sticky.
Mine is the third compact TLB, between my dad and I. The first, a Kubota, had bar tires on it. The main reason he sold it, was to get rid of those tires. Because of, what they did to the lawn. His current, Honda TLB, and My GC TLB, have turf tires on them. We have used both, over 10 years. Even though apparently, you dealer doesn't approve, we have no regrets. And, it all works fine.
My neighbor has a Grasshopper Zero Turn, with bar tires, and they tear the "lawn" next door up, anytime the ground is less than completely hard. No thanks.
This is one of those things that has been debated here, a million times. And, everyone has a opinion about.
Having a preference, is completely understandable. Suggesting his opinion is fact, is not.
