Aluminum Axle Housing on Smaller Tractors

[TMGT]

Kubota uses aluminum rear transmission/axle housings on the BX, B and LX series with one exception I know of. The B26tlb uses cast steel axle housings with an aluminum center/transmission.

From personal experience and what I've seen on other equipment, the aluminum rear ends on these tractors are not an issue. Like with any equipment, if you abuse it enough you can have failure, but it isn't a weak point.

I've actually seen more problems with cast steel(iron maybe?) axles and transmissions on older New Holland's. I think it's more about design, material selection, and QC, then aluminum or steel.

The Massey Ferguson GC series uses "light alloy" transaxle housings. Not sure if they are aluminum or some sort of pot metal, but more likely aluminum in my opinion.

Several years ago (15ish) I worked at a rental store. We had a John Deere CUT, 33hp but can't remember the model number, that had aluminum rear axle housings. A customer rented it without a rear attachment on the 3 pt hitch. They backed into a concrete curb and busted the rear axle housings where the 3 pt arms attach.

I don’t believe that Kubota uses aluminum axle or transmission housings, or any other company except JD.

I thought the BX did, thought there was a post while back of damage done by a stump grinder. Some of the powershift GL's as well iianm

B series back in the day? OK I see it above ^

Deere 3025E for sure

Aluminum rear axles

How long has Kubota been using aluminum transmission housings on their B series tractors? Has anyone ever had a reliability issue with this? Cracked or broken trans housings? I'm old school and think they all should be cast iron. Deere does the same thing. The only B series made now with a cast...
