First I heard of it. I wonder if it would be more along the line of the Polaris Razor than a souped up RTV? I sure cannot imagine the current platform going 50mph.

Yes, it's true.

Kubota will be debuting the new RTV at their National Dealer Meeting in October.

The test units are 45 mph top speed, but that's not to say the production units won't be bumped up to 50 mph.

I'd love the speed. But I can't sacrifice the diesel engine to get it.

This is welcome news if it's indeed happening!

I too would prefer a diesel but with all the complex and potentially unreliable components required for higher HP modern diesels to meet emissions requirements, I understand why they likely chose a gasser.

Add selectable locking front and rear diffs and Iíll be first in line for a cab version.

I don't remember the specifics, but diesel engines under a certain HP rating are exempt from the emissions requirements. Maybe someone can quote that number?

I believe the Tier 4 exemption limit is 25HP. That's likely the reason the 1100cc RTVs are pegged at 24.8HP. Anything more requires complex and expensive after-treatment systems such as DPF, DOC, SCR, DEF.

I think Kubota will keep the diesels in the RTV line but you just won't get higher HP versions unless you choose a gasser.

26 hp is the boundary, my B2650 tractor is at the non tier 4 limit.

Using the current drive system, which requires a lot of HP, I don't believe the current diesel engine would maintain 50mph on any uphill grade.

I don't see Kubota changing the drive system. So they would have to increase the engine HP and/or the engine RPM range.

With all that said a gasser sounds like the logical solution.

For my uses I'll stick with slower speed to retain the diesel engine.

I seldom use low range and only high range on occasion. I can see where depending on the RTVs usage and application more speed can be desirable (or hp). The way that the tier 4 requirements is implemented in the small displacement diesels (like with the B3350 tractor) wouldn't work very satisfactorily in a RTV. I can see where if they want to increase the hp in an RTV, a gasoline solution would be the way to go.
