Comparison Buying new lawn tractor - John Deere question

[jsprice2@mchsi.com]

Sorry if this is a silly question. Why doesn't the John Deere X series lawn tractors use EFI?
Is a pulse pump carburetor a superior system?

X series is at a higher price point so they can charge you the extra for the EFI. No, a carb is not better. It is cheaper. The only real problem with EFI for lawn mowers is that no one knows how to work on them yet. They will oh they will.....:laughing::laughing:

When you say EFI, the key word is Electronic. Most electronic repairs consist of diagnose-remove-throw away-replace. There is very little 'working on' solid state electronic systems.

There is very little benefit for the user to be derived from EFI in a 50 to 100 hour/year residential lawnmower. The EPA thinks it's saving the world from carbon poisoning. Engine manufacturers can sell the engines for more because it's 'modern.' The repair shops have to invest in diagnostic equipment. The owner saves MAYBE a buck or two per season in fuel.

EFI requires a computer, sensors, injectors, wiring and plumbing. Carburetor needs none of that. I prefer the carburetor because it's simpler, has a long record of reliability and I can work on it.

Not quite lipstick on a pig, but not far off.
Eventually they will all be battery powered or EFI, the EPA has to LOOK LIKE THEY ARE DOING SOMETHING.
As previously mentioned, unless you are a pro very limited benefit to the customer.
Once the computers go in the safety system will also be self diagnosing and computer controlled.
This had already started to happen with TORO and the brake actuator on the Time Cutters.
Computer is a bit grandiose by the way, controller is closer to the mark.
