Now that the transmission is squared away it's time to get back to fixing the minor things I noted when  first looked at the tractor. The light switch was froze, I wanted to relocate the ground cable to a better spot and I needed to free up the front axle pivot which was also froze.

The light switch was replaced with a heavy duty one I had on hand. The ground cable was installed between the dash and the frame originally and it's been found to be an issue with dash cracks and in general bad connections. The fix is to drill a hole in the frame and relocate the cable.

 I had to beat the axle pivot pin out which took quite a bit of time but once out I cleaned up the old grease and rust it was still usable.

I did find the zerk fitting had been sheared off at some point so that too needed attention. I used an easy out to remove the remnant and installed a new fitting.

Reinstalled the front axle and all is well.

I went to Zagrays last fall specifically to look for wheel weights of the 50 lb variety but none were present on Saturday. I did find a set of 35's for a sears for a decent price and picked those up.

My wife threw me a curve ball and suggested we go up on Sunday as well, guess what? There was a pair of 50's...........Grrrrr. Well I'm pretty much broke now.

 

I got to thinking later about a friends rider, he has weights on both sides of his rims. Hmmmm. After some tinkering around I found out the 35's will work just fine on the inside of the rims! I'll be looking for the 50's this weekend at Zagrays and with those that puts me at 85 lbs per wheel. That'll work good for plowing snow next year.

After finding out the weights will work I took them off and brought them into work for a paint job.

The 816 comes factory with what they call a liftable hitch setup. It was a good carry over from the earlier 450 riders and as near as I know these two models are the only tractors to have this.

Some where along the way the PO had removed and lost the lift straps that make this happen, they put some flat bar in place of the straps and then welded it up solid. This held the hitch in the horizontal position. I found a set of replacement straps through a member over at MTF and have these in my hot little hands. Another member made up a few sets of the bushing that are also part of this lift set up and I bought a set.

Now I'm ready to restore the hitch back to factory.

First up cut the welds holding the flat bar, I sliced along the added piece in case I hit it with the cut off wheel it wouldn't matter. I'm only showing one side because the same thing happens twice.

Once both pieces are removed I changed to a grinding wheel and ground the weld remnant off. Ad the straps and bushings and it's ready to go back on the tractor. There was also a bolt holding a mount the trailer ball was attached to. Gravely originally used a hitch pin so on a trip to TSC I picked up a new one.

I'm getting closer to were I'm currently at with this project, thanks for being patient.

I didn't get to use the tractor for snow plowing like I wanted to because it started running rough, then the weather went seriously south of 32 degrees and stayed that way for a little better than a month.

So while I waited (impatiently) for better temps I saved and purchased some gaskets and rebuild kits. One kit for the carb and one for the fuel pump.

I pulled the top of the motor apart and removed the heads to de-carbon them, pull the valve covers to check and if need be adjust the valves. I reassembled everything with the new gaskets, adjusted the carb and she purrs like a kitten. I also installed the lift hitch and parked it back in the portable garage.

Now we're currently where I'm at with this project.

The 816 didn't come with a motor guard but other tractors did. I don't know why but I've heard that it wasn't possible because of the way the hitch moves. A guard would hit the motor, you can't bolt it to the hitch without modifying it and so on. I don't care for having that nice Onan back there without some protection for when I do something stupid like back into something and take out the fly wheel. BTW those are expensive, when you can find them.

A fellow gravely owner hit upon the idea of putting the newer styled guard from a zero turn on his gravely rider. His is the 8000 series which is newer and doesn't use the same type of hitch as the 816. The guard bolted right up to it, no problem. The 816 hitch can take attachments much like a three point hitch set up like say a york rake and pivots at an angle. It moves a lot differently than the 8000 hitch which pretty much only goes straight up and down. 

I got to thinking about it and a plan formulated in my head. 

I went to my local Gravely dealer asking about the guard and it turns out he had one out back from a machine he sold. The owner of that machine wanted a bagger set up so the guard had to come off. He didn't want the guard.

I bought the guard and went to work on my plan. All I needed was some angle iron, four bolts and the hitch pin I picked up earlier. I also figured while I was at it that I'd make the word Gravely and light it up from behind with an LED light. It will act as a tail light when working out by the road. I'm also thinking about getting a flasher unit and wiring that into the LED light. The tractor only came with reflectors.

Now to get it installed.

As you can see there is plenty of room when the hitch is sitting level. I also tested it with the hitch fully raised and lowered. Still plenty of room.

Time to hook up my cart and put the old girl back to work. My work schedule got real crazy last fall and the temps took a big dip so I wasn't able to finish my fall clean up.

The great thing about this is if I need to put an attachment on the hitch like a tiller or a york rake then I just pull the hitch pin and slide the guard off. It takes less than a minute to put it on or off. The attachment will act as the guard when it's installed.

Later this summer when things die down a bit my plan is to completely take the tractor back apart and do a complete paint job with replacement decals.

So until then......

Thanks Ellis. Coming from you that's quite a compliment.

I've been working the old girl a lot here lately and I'm seeing why so many people like this model. It's a beast.

You're doing great! I bought mine new 37 years ago and with a little maintenance these tractors last forever.

Thanks you sir! I appreciate it. The old girl is no where near done. Now that the hot weather is about done here I'm going to tear it down and start repainting it. Plus I'm working on an attachment I picked up recently for it.

It looks like the llama is doing a good job of protecting it for you. Maybe I would sleep better if I got one. Thanks for the in depth photo show.

Ha! My wife and I raise alpacas, that's my baby boy. His mom died when he was a month old and we bottle fed him until he was old enough to go to a grain diet.

I have 19 others so I could hook you up but the shipping would be killer. Lols.

Now that I own one of these, your thread made better sense!
