Checking out the Allis Chalmers WD.
Does anyone have experience with these?
They were one of the first tractors to have a live PTO.
So the PTO can keep going when the tractor is stopped.
C Rogers wrote:I keep hearing this, but how is a big tractor compressing the soil IF the tiller is wider than the tracks??? You are actually tilling your tracks so it is NOT compressed. Also you can have equipment that weighs over 10,000 lbs but they actually compress the soil less than a WBT and YOU walking behind the thing!!! Its all in the width of the tread or tracks as this determines the pounds per square inch so don't think that something that weighs a 300-500 pounds compresses the soil less than a tractor that weighs 3000 pounds. It all depends on tire width and how many pounds per square inch the tool your using applies to the soil, so lighter equipment ISN'T always lighter compression to the soil.
I like the hovercraft idea, I just don't know how it could pull things like a 10 shank chisel plow (same idea as a subsoiler) . Thrust would have to be greater than the pulling resistance and that wind would kill plants. But back to tilling, depending on size/depth of till and depth the roots grow that hardpan may or may not be a factor. I don't use tillers, I have a 2 bottom turning plow, 6' disk w/18" disks. Along with field & row cultavators and a 3 shank chisel plow. I do minimal tillage though but can't do no-till without using chemical herbicides (which I REFUSE TO USE) so for now I only chisel plow or use cultavators when needed. But the only way I see to truly eliminate compaction would be to double dig (bastard trenching) or if someone had tons of compost to make lasagna raised beds. But me farming acres, this would be cost, time and labor prohibited. So going full circle back to OP, I personally need tractors. My requirements also need 12" + ground clearance (my Farmall has 18") and it must have over 4' width between tires to straddle my 4' wide beds. Most subcompact tractors are not tall nor wide enough. Larger new tractors are ok, but are overkill. This is another reason I luv the old iron better than the new ones, besides show me any new Kabota, JD, MF etc., that in 70 years will still be running like my 1950 Farmall or implements that were also made in the 50's.Travis Johnson wrote:
You are partially correct in this...
You are right in that soil compaction depends on the surface area of the traction area, and why my bulldozer produces less PSI then me walking. It might weigh 10,000 pounds, but it also has a lot of square inches on the ground to spread that weight over a large surface...far more than my walking tractor and feet. And bigger tractors can have less ground pressure depending on how big their tires are, and how many, compared to my narrow tired Kubota. That blasted thing cuts right through sod during mud season because of its narrow front tires.
But rubber tracked machines often get billed for being "less prone to compaction", but that is not the case. Look at a worn out set of rubber tracks and you can see it. The rubber is ALWAYS worn out down the center where it rides over the bogie wheels. That is because the rubber tracks flex. Yes, it is nice because they do not chew up a field so much like a steel tracked machine, but that steel does not flex, so they float all the machines weight over a larger surface. With rubber tracked machines, compaction is actually worse because all the weight is concentrated over those very thin bogie wheels. They do help with traction in mud though because as they sink, the tracks spread out and gain some traction to the machine, but it still has a center spot where the majority of the weight is being concentrated.
However, in the case of the rototiller, the rototiller is the actual machine that causes compaction, not the tractor wheels. That is because as the implement churns over the ground, where the tines hit are "fluffed" up, but there is vibration in the soil. Just below where the tines strike, those smaller particles of soil are being vibrated to compaction. That is why rototillers are very poor implements of choice for gardens. Sure they look good on the surface, but they really are creating hard pan below the prevents root penetration, and it discourages water filtration. Basically it is one big tub of fluffed up soil with lots of hard pan all around it.
Plows and disc harrows are not really much better, especially the roll over plow because it has all that weight pressing down over the ground as it slides along. They are somewhat better because there is not as much vibration, nor churning the soil to small particles though like the rototiller. That is the reason why rototilled gardens need so much irrigation.
Of course no implement of choice really matters if a person shanks the garden spot or field with a subsoiler, because it breaks up that compaction. That compaction is referred to by a bunch of different names, including hard pan, or even "reached plow depth". And of course the shank plow has a bunch of names too like the shank plow, subsoiler, or Yeoman plow...
All we can do I guess is shank the fields when we have to, and hope Hoovercraft Tractors come out soon! (LOL)

Based on the scale drawing the Kroll Crane below, if that crane were plopped down dead-center on our land, I could access much of the property out to the end-reach of the crane. I could pick up timber and fire wood as well as anything else needing to be raised from whole buildings to pigs to apples off the tree....and probably figure out attachments that would mow, till, chop-and-drop....the works. No soil compaction, no flat tires, no skidding wheels, it would swing right out over the river for some pike or bass around dinner time and provide a deer and goose hunting stand to boot. Flooding??...who cares when I could just pick up the whole house and drop it back down on the foundation when 40 days and 40 nights have passed.
Now if I could just get Deere and New Holland to pay me to keep the idea quiet!... :-)

HA!.....Don' think the town wasn't planning that when they installed your 2' culvert! We are on a river as well in one of the flattest regions in the nation and spring flooding is notorious. In many respects, the 'planning' for flood mitigation in the larger local urban areas is all about keeping water out of the urban areas and backed-up into the rural areas. Hence, when bridges and culverts are put in, they are sized "appropriately".....that is to say, to encourage the water to be held back more in the rural regions. Needless to say, the farmers and rural landowners are not ignorant of this tactic and there are various legal challenges that arise as a consequence. I suspect that if you decided to upsize that culvert on your own dime and efforts you would be notified of the violation in a right hurry.....
