Rear wheel width setting vs. Bucket Width

[TerryR]

Further more, widening treads is intended for crop row spacing, not stability.

Really? I set mine at maximum width for hillside stability, and many threads I've seen here seem to recommend doing exactly that.

I set mine out further for stability too just not to the maximum. I was told that the maximum setting was not intended for maximum stability. Maybe an ole farmer will chime in.

Do you have a box blade that will cover your rear tires or a back blade that could be offset enough to cover one tread?
I'm thinking of road building work or digging a trench, where most of the bulk excavation can be done with the FEL.
Then the edges of the excavation can be cleaned up with the rear implement.
The ballast on the back would help your FEL performance & traction, too.

I don't have a box blade or back blade yet. Still looking for one. Do you think a 7' back blade would be too much for a Ford 1920? This would cover both tracks, unless heavily angled. Would I be better off looking for a 6' blade that can be offset?

Something like this maybe: Everything Attachments 7ft 6 Way Deluxe Value Scrape Blade for Compact Tractors with 25-50 HP V2.0 I was surprised to see this blade only weighs around 325lbs though. The 7' version weights in a 345lbs.

Thanks,

I grew up on a farm does that count??? The further out you set your wheels, the more stability you create. It's simple mathematics.

A Ford 1920 will handle a 7ft grader blade nicely. You could try different wheel widths until you find a setting you like.

Sure it counts but when you get too wide in the rear you start to create a tricycle. Your front axle is free floating as im sure you are aware. There is a false sense of security by going to far, or so says my simple math book.

My rear tires are set at max width (80") and my bucket is 72". I do have Rimguard in the rears (755#/tire) and always have some implement on the 3-point. I have never experienced any instability nor have I ever had any problems relating to bucket vs rear tire widths. Oh, BTW, my front tires are set as wide as possible also.

You have a tricycle no matter what the width of the rear wheels - making them wider doesn't make that any more true. But the wider the wheels of the tricycle the more stable - simple physics. The wider the downhill wheel the steeper the hill has to be before the center of gravity lies outside the vertical plane through the point where that wheel touches the ground. And, the further up the hill the uphill wheel is, hopefully loaded, to better resist overturning.

Sorry but you can not get too wide. And that goes for both front and rear. The point of no return comes when the center of gravity of the tractor and load in the bucket goes over the line of rotation which is the line from the outside edge of the rear tire and the outside edge of the front tire on the low side. The front axle will get to is stop on the swivel before this point so this often erroneously made claim does not matter at the point of no return.
Being set too wide may be harder on axles and wheel bearings then a narrower setting but that is a different issue from role over safety margins.

I agree with you on most of this, but wonder about this last point. When you are on a significant side hill I'd think that once the uphill rear comes off the ground enough for the front axle to hit the stop you have likely already lost it. Does anyone know of any actual facts on this?
