I am wondering if we will see lower horse power tractors go back to gas but utilized fuel injections systems??? The reason I am thinking this may happen is the cost of making the diesel engines EPA compliant. I think it could be done easier/cheaper with a gas motor. Also fuel economy is a lesser concern on the smaller horse power tractors. Your not going to be using them at full load near as often. A 200 HP MFWD tractor pulling a deep ripper would suck gas like crazy but most smaller utility and compacts are rarely used at full load for long periods. So I would think the fuel economy would ne be that bad.

Actually saw a 20 page study done by KUBOTA, market research along those lines. There real concern was market price resistance to our big (like 36hp) front deck commercial mowers. Those mowers now have to be EPA compliant. Looked a propane, gas , and cleaning up the diesels in the end went with diesel. NOW part of that may have been KUBOTA has never really had a true gas engine. At one time we took a 24 hp diesel and put ignition and made it run on gas , sold it to cub cadet and they performed flawless but manufacturing cost was too high. Is there a market in the compact utility for gas, I feel it would have to really offer something like a 6 or 7 thousand dollar saving in initial cost. Doubt that any manufacture UNLESS some cheapie from china brings something then they still have some epa issues to deal with.
I have thought the same thing but for different reasons. I am waiting to see a compressed natural gas tractor. Seems like a logical thing if you live in an area that produces natural gas. You could probably have your own well and produce your own fuel.
A gas tractor with computer controlled fuel injection would be much more fuel efficient than one with a carburetor. Could probably get within 20% of a diesel. Diesel fuel has more energy per gallon than gas so a gas engine won't ever match a diesel on fuel volume consumption but should be able to equal one on energy produced per energy available in the fuel.

I've been looking for the same thing for the past couple years now. I wouldn't mind seeing a 50 hp or so gas tractor come out. A newer version of my JD 2510.
I'm dreading the day when the so called "enviromentalists" convince the EPA that we need to outlaw all the pre emission controlled tractors that we all know and love.This summer the EPA is gonna make a decision on whether or not to outlaw modifiying vehicles for racing or other offroad uses.No matter how old or new the vehicle is.I call it back door socialism.

I prefer deisel even with the smell and noise. It is much safer to transport deisel and I don't have a big enough operation to have fuel delivered. I have a 50 gallon deisel tank, just set in the back of my pickup with forks on my tractor. I have a JD backhoe, an ATV with a Kubota deisel engine, A 1750 Kubota with a 3cyl deisel and a 48inch conventional style lawnmower with a little water cooled deisel engine. I hate haulling gas in 5 gallon cans and treating it with stabelizer. I find in the longrun it is cheaper to buy the perfumed non-ethynol $5 a quart fuel for my trimmers and chain saws.
I think we will see it. I have a Honda Four Wheeler ATV and it has an excellent F.I. system on it. No choke, starts up great all year long and is extremely reliable. I would buy a F.I. lawn mower in a heartbeat. of course if the nnalert get the presidency then they might just reel in the EPA Nazis and who knows what the market will produce. I still miss my mid 80's Toyota diesel pickup! America needs a small pickup once again. JB
Was looking at a new Cub Cadet riding mower and the salesman showed me a fuel injected engine on one of the 2016 models. I think you'll see direct injected gasoline engines with a turbo on some off road utility type engines. Fuel injection will show up on lawn/garden equipment fairly soon.
Bingo!
I've been predicting this for several years now due mostly to meddling by the federales.
The federales have seriously damaged the HD PU market and are now doing the same to the sub 100 HP utility tractor market.
Expect to see the reemergence of gasoline powered utility tractors within the next several years.
That said, once such gasoline powered tractors become popular, the federales will attack them as well.
There is NOTHING with which the federales will not meddle.

I don't think that this would be too bad... Maybe if our "old systems" are outlawed... We might be able to buy aftermarket conversion kits? Gotta say, this man has some "engine"-uity.

Fuel injection has worked very well on snowmobiles, motorcycles, ATVs and outboard motors. Fuel economy and emissions improved. As it becomes economical, I think we will see it on lawn mowers and other small engines too.
In the odd chance that the cost of gasoline ever dropped to around half the cost of diesel fuel for an extended time, I think we'd see a mad rush to build new gasoline engines for the 200+ HP tractor market and for large trucks.

Back in the 1960's gas tractor engines were significantly less expensive to manufacture and to overhaul than the diesel engine in the same tractor, because the stresses were much lower: lighter crankshaft, lighter connecting rods, lighter pistons, 4 main bearings instead of seven, smaller air cleaner for the same horsepower, off the shelf fuel systems cost less, etc.
Back then gas engines did not have the longevity of the diesels, but engine technology and lubricants have improved a lot since 50 years ago. In the 1960's car engines needed overhauls by 100,000 and only diesel truck engines lasted to 250,000 miles without an overhaul. I suspect, with good maintenance, a modern tractor with a gasoline would probably average well over 10,000 before needing an overhaul.

In Green Magazine, there was an article about a man who was getting started making an electronic fuel injection conversion for John Deere 3010/3020 and 4010/4020 gasoline powered tractors. I saw a photograph of his 4010 at a John Deere collectors event from just recently. I believe his results showed about a 10 percent increase in horsepower with a 20 percent reduction in fuel consumption. His source for components was from a company referred to as FAST, or Fuel Air and Spark Technologies. Their website is www.fuelairspark.com. I believe in the article, it was noted the conversion for the 4010/4020 would be in the vicinity of $3500. I think that is about 3 to 3 1/2 times what a new Zenith carburetor runs today. I tend to believe there is a market for this sort of equipment. I would rather have a gasoline powered tractor for my yard work and snow removal, versus the diesel tractor I have today.
The video of the BRx was interesting. That was a very nice running 2 cylinder tractor!
