What year did the massey harris 101 jr go from the screened grille to the louvered grille, flat top fenders to the clam shell fenders, cast rear wheels to pressed steel rims and the wavy center front rims???? Cant seem to find any info on them!!!!

It is my understanding that only the very first of the 101 jr's. had the screen grill and I think the numbers are very low by comparison. The started out with a 124 Continental, graduated to a 140 then finished up with the same 162 engine that came in the jr's replacement, the 30. If that is true, the majority if not all the screen grille 101 jr's would have the 124 or the 140 possibly. I do not know the production numbers, but that should be easily obtainable information. Probably didn't help you out any, did I....

Hopefully there is someone reading that has real and factual information as I have wondered this very same thought myself.

Thanks for the info massey man. According to serial number
mine is a 1941!! It has the screened grille, cast rear wheels! It has
the clam shell fenders on it but got the flat top fenders with it!!! It
also has the wavy from center on front wheels (as dose my 1938
101)!!! Not sure of the motor but am sure it is the 140 cu in!!! Just
cant seem to find production figures or info on it!!!

The Continental engine info will be on an aluminum tag the opposite side from the carb. It'll identify the cu. in. by the number stamped in as 124, 140 or 162. I'll dig out an old Massey data book tomorrow and see what's there...if anything specific I'll let you know.

The Massey Tractor Data Book by Keith D. Oltrogge shows a picture of an "Early 101 Junior" and it shows the screen grill. Introduced in 1939 they built 1,156 row crop versions and 926 standard versions. It says the early ones only had the 124, but many were changed later to the 140 or 162's as the blocks are identical. They went to the 140 in 1940 then in 1943 went to the 162 according to Oltrogge.

Nothing in the data book about fender type or wheel type at all, just the photo of the early one with the screened grille. It isn't uncommon to find all kinds of mix and matched wheels, fenders etc on all brands.

If you solve the delimma, please inform us. Thanks man.

You can also tell the size of the block by the casting numbers.

Based on the blocks I have here.

A400-418 is a 124cu in
A400-422 is a 140cu in
A400-428 is a 162cu in

These numbers can also be ground off and re-stamped into the block.
