Brush Hog mods

If you keep adding new parts, pretty soon you will have a new cutter.

Right? She's built tough... This old farm stuff was built right so she will last somebody a long time.
I will have to fix the gearbox seal/gasket too. Leaking like a sieve. We extended the rear wheel mount so the wheel spins around when you back up. It was originally built for forward travel only.

I am confident the brush will just fall over on its own once the brush sees it.

It's so heavy that if it fails to cut I can use it as a box scraper.

Progress. No pictures
Finished welding the chain guard on. Put new zerks in the u-joints and gave them the grease they have been waiting yrs for.
I need to flip it over and finish welding up the underside. Then aside from a leaking differential gasket
I'm nearly done + ready to rock and roll
Praying for rain so I can cut without high fire danger... no rain here in 100 days

Depending on what part of Calif you are in, that rain issue may be solved quickly! Looking forward to seeing it.

 

[scootr]

Me too. No rain the last 3.5 months. Raining east of me all day.

So yes. We got some rain. 2-4 inches depending.
Yesterday I P-washed the gear box and located the oil leak...
Today I brought it back into the shop and put it on the horses to fix.

Got a couple of pictures. Bad gasket where the shaft bolts to the housing... the good news is the gears show little wear after all these years
I cleaned everything up... ran down to O Riley's and got some RTV gasket material. She should be good to go in the AM.
Shame about the oil spill screwing up the metal for painting... any way - I am looking for a spot to mow.

Ugh! New problem now is RTV gasket is just too thin. Gear lash or clearance is too small - she is binding. I'm going to have to get some gasket material and try again. the simplest things get complicated sometimes.
Need to maintain the OEM thickness.

The gears look the same size on the pictures, is that true? Do you know the ratio of the gearbox?
