page 149 in TC 37F
Well, the parts book sure shows them to look different, but it's interesting to see they have the same part number.
From an IH spec sheet from the four bar grill era (early 1960's).
Wheelbase on a Cub Lo-Boy is 62 inches. On a Cub it is 69.3 inches.
Length 97" vs 99"
Height to top of steering wheel 55.3" vs 62.8"
Minimum ground clearance under front axle 13.7" vs 20.4"
Minimum ground clearance under rear axle 17.9" vs 23.8"
Turning radius without brakes 9.6' vs 9.3' and with braking 7.6' vs 8.7' (Don't understand that one)
Weight distribution with operator; Front 520 vs 620, Rear 1320 vs 1220, Total 1840 for both
I am thinking 229XX or so , but only speculation on my part from the ones I have had
All versions of the parts catalog I have looked at show the left and right fenders with the same part number. The early Cubs came with identical left and right fenders. The part number was 35961R11. Catalog TC-37D Rev 1(12/54) stilll uses the original drawing with a part number of 35961R12. The change to R12 indicates some minor change, like maybe to the reinforcement on the lower edge.
Catalog TC-37E (1/56) uses a different drawing and part number 362901R91. Again the same part number for left and right. The drawing is A-40672. It shows the reinforcement plate on the left and the right seems to suggest a shorter front end. The final catalog, TC-37F Rev 6(8/79), has a minor revision of the drawing to A-40672A. The drawing differs in that 3 holes were added to each fender for the warning light bracket. The part number is 362901R92. Again this indicates some minor change from 1956, probably the light bracket holes.
From observation, is is pretty clear that IH eventually made different right and left fenders. After 185,000 or so, they added the helper spring reinforcement to the left fender. I have never seen one of them on a right fender. Possibly, they chose to simplify replacement parts handling by only supplying left fenders. Timewise, the change to 362901R91 matches up close to the helper spring reinforcement. Likewise, they could have clipped the front of the right fender on late LoBoys but stuck with only left fender for replacements. The likelihood of anyone ordering a replacement right fender on a population of about 2,000 tractors is pretty small. It may have never happened. So it seems possible there was a clipped fender that was never reflected in the parts catalog. However, the parts catalog doesn't show any part number to go with a clipped fender.
The other possibility, of course is some modification after the fact. A sample of 3 tractors could track back to a single dealer, or even single customer. A branch could have modified them for a contract sale. Didn't Dale Saw have one of the very last offset LoBoys? What did the right fender on it look like?
If all of them had the cut off fender, I would only hate them 1/2 as bad. I will not own another unless it falls into my lap.
Too hard to get on, too hard to bend over to work on.
I guess it may have been an option?
Yep Dale, it's obvious that the people that say a Lo Boy is easier to get on and off have either never gotten on or off of one or have a Lo Boy and never been on a Cub! A real challenge is one with a 1000 loader, pretty much need a pan seat and scramble up over the back to get on it. In the summer I get shorts hung up on the FH depth adjuster and in the winter I do everything I can to avoid changing the angle of the snow plow
Later models the part number should not be the same because of the fast hitch helper spring reinforcement (shown in picture below) and the holes for the flashing light. They just are not interchangeable. They used stout gauge material and only a real pro could make that fender look like that, my money is on factory made.
My 65 (with IronGuard paint and mascot) sure doesn't have the short fender.
