Thanks everyone, the kind words are much appreciated.

Mike and I finished the hub builds last night at the shop and threw them on. Basically, installing the studs. Got some pics.

Haven't been here for a while that's neat. Good job on the fabricating.
Note, I noticed on my fel/backhoe project the frame was easy to twist and flex. I had the jack stands more to the rear.
It's really flimsy. I know your not there yet just food for thought.
I'm technically misunderstood at times i guess its been this way my whole life so why should it change now.

Thanks. Yes, I'm not overly impressed by the "engineering" on this tractor when it comes to the frame. I'm especially alarmed at how the tranny/transfer case/finals are attached to said frame. It was born to fail, and in this case, it did. I will be addressing these issues through additional attachment points and added structural elements. Appreciate the input Bill, please don't hesitate in the future :thanx:

I've heard this complaint a lot about folks working on the number series lo-boy tractors, about how flimsy the frames are. Honestly, you're correct, the frame is really lightly constructed. However, you need to keep in mind the intent of the tractor when it was designed, and what other tractors were out. The number series tractors were meant for "estate and commercial mowing". That's it! They weren't meant for construction work, farming, digging pits, running a back hoe, etc. They were just meant as big lawn mowers, nothing else. Also, keep in mind that IH had a LOT of other tractors to handle all kinds of other work, so when they meant that this was an "estate mower", that's what they meant. They had lots of other options for heavier duty work, and this was not. However, the fact that so many of them are around 40+ years later is quite a testament to how well they were built!

Agreed on all counts. Especially, the longevity reference. Although, I think that more a testament to the drive train. These tractors are numerous on LI, as there were many estates(still today) and there was good dealer support. Tryac IH in Riverhead was a place I visited with Dad a lot as a lad.

As to the frame a bit further though, as someone who designs and builds parts/systems for the USN etc. and realizing that IH must have had very good engineering resources to bring to bear, I just can't understand how this got past them. Two points of attachment, and a profile that creates a weak fulcrum point. This coupled with the large oval frame hole right in line with the weak point just doesn't tell me much thought went into this. I plan on adding a gusset to make a third point of attachment on the transmission. The tapped hole is already there. That should greatly strengthen the area. Well, in theory any way :wink:

Oh, I agree completely. Extremely weak spot and it doesn't make much sense at all. I know the transmission is bolted to the frame near the front of the transmission too, so maybe the thought is that there shouldn't be any twisting moment at the back and it's only there to hold it in place? Regardless, yes, very weak spot on these tractors.

how fast are you anticipating with the 1/2 diameter of stock tires?

Might need to turn a creeper around and use it as an overdrive to compensate for the tire diameter.

Hello, anybody crazy enough to still be here? If so, you might want to sit down for this..........I did a little work on the LBC this weekend :omg: Just proves fact is stranger than fiction. Anyhoo, after refreshing my memory, I got back to fabbing up the new nose. If you recall, the grill/nose is from a '53 Farmall 300. It will require some alts to fit and get the look I want, though.

The first thing to do was to fit and weld in the old radiator stanchions. This required some cutting on the frame rails. This was mainly to allow the radiator to slide down within the frame to achieve a lower look to the LBC.

Having had the plasma cutter for a bit now, incredible tool. Clamped up a straight edge, and started cutting.

Image

Here's where things ended up.

Image

The original radiator stanchions were still used, but on opposite sides. This changed the angled portion to the back. The Farmall grill will be plumb, as opposed to the LoBoys which was sloped. They were also shortened/narrowed to compensate for the radiator dropping into the frame.

Image

Clamped, welded.

Image

Image

Radiator fit in place.

Image

Image

Next up, the grill/nose. I love the vintage look, and more importantly, the IH tie in. What doesn't work is the width and the grill slope. The stock width was 19", the radiator is 17". Behind the engine will be the '49 Cub gas tank/dash. That is 15" wide. My goal was to make the grill/nose width a touch over 17" wide. Two reasons, one, to ease the transition aesthetically from nose to fuel tank. Two, to make the nose look longer..........and leaner. Faster, if you will.

Here's the stock look mocked up.

Image

This is something I want look wise, the tires ahead of the nose.

Image

Back to the plasma cutter. After the initial surgery. The black lines indicate what will be cut away for narrowing.

Image

Initially, I was going to weld the outside pieces "flush" to the center rib. But after dry fitting I really liked the look of the center rib over lapping the outside pieces. It make the center more prominent, bolder. I was happy with the newer lines. Next, I have to noodle out some ways of attachment and take the angle from the grill. Stay tuned :fing32:

Thanks. Fall, Winter is generally when I get to work on these type things. Should be posting more frequently. Appreciate you "keeping the faith" :D
