Rotary plow any tips?

[RichardTX]

I looked at the manual on old gravelys and figured out the problem the small arm that goes from the plow housing tube housing to the mount on the advance housing was missing and I didnt' even notice it, No wonder it jumped around. So I fabbed up a short term replacement out of a little piece of angle iron and it worked 100% better when going forward :thumbsup:

Tilled the crap out of the garden again just to make sure......double tap.......

I tried out the cultivator but I found the only 3/8" bolts I had were too long and locked up the ring gear need to put on some lock washers and try it again.

Using a rake is to much work to level it all out.

When I break new ground, I start at a modest depth and plow per the manual which means starting at the center of the area and always make a right hand turn at the end of the furrow.

Then I set the depth a bit deeper and reverse the process meaning that I start at the edges and work my way in to the center. I then set for max depth and finish up using the book method. The reason for alternating is so that the dirt is more or less level when I am done and no raking is required.

Having a ditch on both sides of the garden is good. It helps keep excessive rain from flooding the seedlings.

I inherited an old Model L8 with a ton of attachments.

Right now it has the rototiller on it, but I need to switch it to the rotary plow.

Do you just remove the rototiller from the 4 bolts under the safety shield?

Thanks.

Ya, you remove the four bolts and then put in a little bit shorter ones to hold in the bearing/seal.

Make sure everything is full of oil before you run it. Old dried up seals can leak badly. Here is a picture of one plow drive I disassembled. There was about 4 tablespoons of nasty oil left in it.

Thanks for the replies.

I removed the bolts and put in the shorter ones.

The attachment dog was bone dry on oil, so I put in about half a quart of SAE 90. I started her up and engaged the PTO and the oil went everywhere

Looks like I will have to get news seals for the attachment dog. Any suggestions on where I might find these seals and a blow up of the take down and reassembly of the gear housing?

Thanks again for all the help.

Can you post a picture of what you are referring to? I haven't the foggiest notion of what you are talking about.

If you look at the manual here:

http://www.oldgravelys.net/pdf/Model_L_Instruc_Man_0364.pdf

On page 16, figure 25 and page 17, figure 29 it shows the picture of what I was told was called the "attachment dog."

I need to take it apart and replace the seals in this "hound." If I had an interior blow up pic of the the device, I could be more secure in stripping it down and putting it back together.

Thanks.

Replacing the seals in the rotary plow drive is not difficult. There can be shims under each bearing cap. Do not mix them up or lose them. The shims were selected when it was built at the factory.

Here is a better parts diagram.

I would remove one cap, install the new seal in the cap and reassemble. Then do the other side. If you need to replace the horiz shaft seals, remove that shaft and housing assembly from the drive and then disassemble on the bench.

Don't damage the seal retainers. Things will get complicated if you do..

Richard's (gravelyparts.com) has seals. Just call them and tell them what you want.

Their quick parts guide for the rotary plow is on page 12 at http://www.gravelyparts.com/pages/CustomPage/Index/3124
