Mid PTO delete?

[PitViper]

My mid PTO is in constant mesh with the rear PTO. It has developed an oil leak and I was looking up the seal on Messicks and was wondering, why not just get rid of it and bolt a blank cover plate in its place? My concern is, does gear 040 help support the gear for the rear PTO? Is there some other reason this would be a bad idea?

Keep in mind, this tractor is 30 years old. It doesn’t have a belly mower, I’m not putting one on it, and even if I did want to, the likelihood of actually finding the proper belly mower that fits it are zero.

Before the trolls start, yes, I realize a blank cover plate would require an oil drain plug.

I have a B1750HSDT with 60" belly mower and such mowers are still available should you want one. Indeed, I have seen used ones from time to time (no, not regularly).

That said, it would seem to me that simply replacing the seal would be less work than fabricating a block off plate with drain plug even if such is doable.

It looks like the whole assembly will just drop out, and you could cover the opening with a plate with a drain plug.

You would still have the assembly to put back in, in you wanted to in the future.

If it works for you, why not do it? The mid pto is an option on some tractors. Those without it probably have a cover like you are proposing.

It is a feature which will add value to a possible future owner who might want to power a front blower or sweeper.

Yes you can pull the mid PTO without any issues to the system
We have no trolls on here... I make sure of that!

You really don't have to have a drain plug on the block off plate because it still drains via the other drain points.

Why couldn't he remove the assembly, remove the stub shaft and make a much smaller plate from steel and reinstall the assembly. It has a drain plug in it (in the parts picture)?

I'd think it would be simpler to to remove gear 40 and put a new seal in. The PTO would no longer spin and the cost would be a seal and a gasket.

That is THE drain plug for the HST. Mid PTO is the lowest point of the transmission. Without it, changing HST oil would require removal, or at the least loosening of, the cover plate. Drilling and tapping a hole is not a big deal lol.

Looking back at the rear PTO diagram, the rear PTO shaft drive gear (gear 090) is supported by bearings on both sides, so gear 040 on the mid PTO doesn’t support it.
It does however appear the rear PTO oil seal (080) is much more of a PITA to replace.
