2 questions1 is it normal for my to 30 to drop oil pressure while
bush hoggin the thick stuff . And I've got a small amount of oil
dripping out of two holes on the bottom that have cotter pins
stuck in them when hot is that ok or should I get worried.
 
Oil pressure is determined primarily by the bearing clearance from the main and rod bearing clearance on the crankshaft. When the engine is cold the oil pressure is generally higher than on a warm engine due to the expansion of the parts.
So, hot hogging will cause the oil pressure to drop. Especially with a slower turning engine.
 
If your talking about cotter pins in bottom of transmission housing the rear seal is leaking or transmission seal is leaking. Small amount I wouldn't worry a lot, unless you just want no leaks. You have to split tractor to fix.
 
Regarding your leaking rear crackshaft seal or leaking transmission input shaft seal, I recently purchased a can of [b:5554169d40]Liquid Intelligence 230[/b:5554169d40] oil additive.

[u:5554169d40]I make no comment or recommendation on the product[/u:5554169d40] as I have not yet tried it.

However, it [u:5554169d40]may[/u:5554169d40] solve your leaking seal problem.

It appears to be available in both Australia and the USA.

Thicker grass slows the rpms and thereby slowing the pump gear and with any worn engine the pressure drops off when hot but it's not because of the leak.
 
Does the steering gearbox work from the same GL1-90
oil? What I mean is,does it pump oil up into the steering box,or does it require being drained separately and filled with a different lube?
I don't mean to sound like a big dummy!!
My grandfather passed away and left the tractor and
I never asked him that question.So,I figured I'd ask
you fellers.Thank's for being here on these forums!
 
No dumb questions on here just those with less seat time, The steering gear filler is under the battery box.
 
The steering column has its own oil supply inside the steering housing and that plug you should see at the bottom part of the steering column is where you add oil or better yet corn head grease. You can find this at most tractor dealers. Corn head grease is a thicker oil so if your seals are a little bad it may not go past them as easily as the regular GL-1 oil.
