    Is it true that starting in 2011 mowers will be regulated with regard to evaporative emissions and that due to this tank capacity has been very significantly reduced?

    I knew about the emissions regulations but why will that result in small tanks?

    That can't be true. Otherwise we will be driving cars with a 4 gallon tanks. Farm tractors with a 6 gallon diesel tank. Maybe with the price of gas skyrocketing we will only be able to put 4-5 gallons in them.

    I still dont understand why emissions will yield smaller gas tanks? The scag cheetah holds 16 gallons of fuel and i believe they are all set up for the new emissions standards

    seems to me the more you have to fill the mower at the pump and especially with a can the more evap emissions you are going to have

    The problem is the plastic that they make the tanks out of isn't vapor tight. In other words, the gasoline evaporates right through the plastic. It's also a problem with the hoses and primer bulbs too. All of these must meet be certified for compliance before they can be used.

    I don't know why it would require smaller tanks though. Portable fuel containers have the same requirements too.

    Just picked up a brand new 26efi Walker and the mechanic was going over it with me , he mentioned about how the fuel tank has changed to suit the new emission laws coming into effect . Alot of what he said went over my head ( first ztr ) but i think he said that the top of the tank on older walkers goes straight across ( allowing to fill right up , On mine the top of tank goes across , then cuts down , then across to fuel cap . So you can only fill to fuel cap which is on right hand side of tank , and on left hand side before it cuts down just has air in there i suppose , As i said alot of what he said went over my head so what this means or what it does i cant say .
