Rotary Cutter Bush Hog Gear Box Leaking

[LD1]

AND rotary cutter gear boxes are still leaking!

SR

And 99% of everything that was relevant on this forum 15 years ago is still relevant today. Whats your point?

I was just reminding everyone that the thread is 15 years old......so if someone is looking for an update, or hoping to see a response from someone that posted 15 years ago and has been absent for the last decade.....dont get your hopes up.

There are also dozens of threads on the topic that would all be more recent than this one.

Experience with JD 127 Gyramor: #2 grease + gear oil leaked out; #1 or 0 grease stayed in. No problem for years of hard use adding an ounce or so each year.

Did you mix the gear oil and grease in some type of bowl before you put it in gearbox? Because if you didn't, gear oil would still leak out. If you have sealed bearings it may be a maybe. But open bearings I want it to flow a little and get in those bearings. I dont know how much you use one. I sometimes use one two weeks, all day everyday. Done a pipeline or power line now and then too. Just imagine, get a call and this dude done got a contract cleaning a pipeline from Texas to Mississippi, across the "L" part of Louisiana. Jungles are in North America.

No, I put some gear oil into the RC gearbox that had #2 already in it and immediately ran the cutter in normal use. After an hour or so everything was gone. I have used only straight greases since w/no problem.

Even the grease you pumped in was gone? I mean grease pumped in first time?

Here is one: grease in a rotary cutter gear box?

MY point is the same as your point, who cares how old it is, it's all still relevant!

I find that #2 is ok when the bushog is used in shock producing situations often. Too much smooth running is not optimum as the grease stays pushed away from gears and bearings. I like #1 or 0 which almost flows. TSC economy grease is ~ #1.5 -- its seems to work well. Convenient.

I do hours and hours of fields just like this,

for days on end, never a problem with lack of lubrication.

Not sure why you want to turn this into a debate.

I never said it wasnt relevant.

And I dont have any issues reviving old threads.....especially if someone has a specific question directly tied to said thread.

This wasnt the case here.....there was no question for clarification from one of the original posters of this thread.

I was just throwing out a reminder of the age of this thread, incase someone was thinking they were gonna get a response from one of the original posters.....some of which havent been active here for a decade or more

Yes. It was still residual oily/greasy but no reserve bulk. Maybe I added too much oil, but I tried to err on the low side. Maybe the grease thickener was incompatible with the gear oil.

From sound only, I perceived less than optimum gearbox lubrication with #2 after prolonged smooth usage. Chop a few trees with it or hit a couple cinder blocks and its all better for awhile. The JD127 has no stump jumper so, driven by 45ptoHP, it really shakes when it hits substantial objects. I never noticed any sound from the gearbox on #2 until it accomplished all the rough stuff and became mostly a grass mower, mainly on a smaller tractor.

Yes, but did you mix the two together before it went in gearbox?

Sawer Rob, Off topic some, but, how do you keep your cutter from digging in during frontward pulls? I have a Woods BB60 and unless I drive in reverse it will surely dig in on one side or the other and leave a gouge in my clay soil?

I need to "constantly" watch the front edges and make adjustments if going forwards! It's easiest to just drive backwards - although very hard on the neck!!
Your ground does look flat and mine has nooks-n-crannies but I wonder if there is some trick that I haven't yet discovered. Thanks Greg

Position control on the 3 point, I set it so the front of the cutter is a couple/three inches off the ground.

Is your TYM rear wheel stance narrow in comparison to the width of the bushog? That accentuates l/r leans.

 

[ROUSTABOUT]

It says everything was gone, so even the pumped in grease?

 

[SPYDERLK]

Im not sure what question remains unanswered in the posts. There was only a little grease - oil patina left coating the inside of the gearbox as in post 29.

 

[CobyRupert]

FYI: IMA, the first thing to check on a leaking gearbox is that the gearbox breather can actually breath and isn’t plugged. Especially if it weeps on sunny days.

Spyderlk, Not really, my BB60 is about 1-2" wider than my rear wheels and it will gouge (rather than slide on top of) the ground even if I'm going straight. I need to be "constantly" keeping eyes on it to not have it snag a chunk of ground. However if I cut going backwards it does just fine. Yet that's real tough on my neck!
I try to keep the front of the cutter about 1-2" above the ground when going forwards but - go through a dip in the ground - and it "always" snags the ground rather than skim on top. I just wondered if I was doing something wrong whilst operating it? The manual doesn't cover operating much. Thanks

IF you have the cutter leveled side to side, and the front is a couple inches off the ground, and you expect it to "never" scrape the ground, then you are using the wrong cutter.

It's a "field" mower, not a "lawn" mower with anti scalp wheels on it!
