How do adjust the neutral for a Thomas built 1985 Ford CL55? Got my machine running today after a repower and it creeps slightly in neutral. Otherwise the maxhine which sat for two years + is doing great.

Are there any stops on the pump at all? Bobcat uses a spring loaded plate with metal stops that when you let go of the steering levers, they pull the pump pintle arms back to neutral.
Can you get any pictures of the pump?

I have a parts list with drawings. i can get a pic but would have to take the seat out again. Today it didn't creep when I first started it, but it did after I moved it so it seems it's not going back to neutral all the time. It does appear to be the right lever as at one point I didn't even touch it and drove forward with just the left lever.....while lighting a smoke...lol
Took 4 of about 30 some stumps out in the back yard tonight. Machine ran great but I did notice a couple times that under light loads the right tilt cylinder would leak. Never did it with a full bucket or empty bucket and after some use it seems to have stopped leaking. I only spent an hour or so digging the back yard down. I am trying to get the back leveled off and using the dirt in lower areas so maybe things won't flood so bad each time it rains. I also want to make it easier to mowe and not be hitting roots all the time. There are also 3 stumps out front to dig up. I have some new growth trees to transplant out back too. May also put one or two out front away from the house where they are now. They grew on their own and there is one Walnut and 15 Maples..... nothing better than free trees! Going to fuel it up tomorrow and dig some more out back. At this rate I can probably get that area cleared in a couple days if it doesn't rain.

Sounds like you sure are having some fun with your new toy :)
They make work so much easier. They are pretty good at packing moved soil too, the tyres pack it down pretty well.
I have no idea how manu hundred cubic metres i have moved with mine at home, i'd never have stood a chance without the skid steer.

I have a couple issues I am working on in my yard. #1: a slope that ends up flooding the neighbors with a hard rain or hours of rain. #2: until May 2005 I had a wooded area 90 ft x 32 ft. The whole section had 30 some trees until a tornado blew through and took every tree there out. I fact of the 42 trees that were in the yard before the tornado only 1 survived! So now I am removing all the tree stumps and cutting the slope down and using the dirt to fill my lower areas. It turns out there is a 2 foot difference in height between the high area and the lowest area. It's obvious when you look at the shop from the West side as it goes from level at the back on the South end and way above ground level on the North end. The East sides level all the way across as I put in 30 tons of dirt before building the shop. So the North and West need a lot of dirt put in. LOL, the pool might be level this year too! For the 3rd straight year it is moving to a different spot but this will be the last time it's moved. It will stay up year round now. There is no way I could do this by hand. Without the machine it would stay as is. I know renting a teremite wouldn't do the job, just not tough enough or heavy enough either.

My Thomas T133 has had neutral creep since the day I got it. The mechanism for returning to neutral in my Thomas is for the birds so I don't even bother setting it anymore. The neutral position is attained by two coil springs that alternately go into tension with the motion (forward or back) of the drive handles. The trouble with this setup is that the hydrostatic drive is extremely sensitive to the slightest control input but the counter balanced springs do not return to the exact same spot every time. Thus the neutral creep.
After years of adjusting and readjusting I gave up and now I just move the sticks back and forth around the neutral position until the noise stops. Done!

Well that explains that! You are correct, it is the spring setup. It doesn't do it a lot but it seems to do it when you first start it up each day. Oh well, no biggy as I expect it now. It was a bit unnerving the first few times it did it though.
You are correct too about these Thomas built machines being tanks. And they are fun to run even without all the bells and whistles.
