I am looking at another project already and don't have the suburban 10 even running yet.
I answered an ad for a 64 sears 725. we may be making a trade for one of my rear tine tillers. The ad says, "runs but wont move, throws the drive belt when engaged." I am not sure what the problem could be. I asked if it would roll in neutral to roll it onto a truck, and he says it has a centrifical type clutch and we would have no problem loading it onto my pickup. Any clue to this problem? What should I look for? If it is a big costly repair, I don't want the deal but if it apears to be something I could fix with some tinkering or adjustments, I do want it.
here's the link to it:

Thank you,
Robert

if its a 725 it dont have any neutral. The earlier tractors used the same tranny type as the walk-behind DB. There is only a forwards and reverser lever. This lever does do the neutral, but only as far as unlocking the clutch. If its popping the belt off it probally in the idler pulley located on the right frame rail under the belt gaurd. About the only parts you can get for the tractors is the clutch plate, most everything else will have to come from another tractor. Keep in mind that this is a hand clutch machine.

I believe it's a 725 because it is a 64 and he said it was "around" 7 horse power. Does this mean it would be an idler adjustment then?

that pulley or something along that drive is locked up would be my guess. I had a similiar issue and the belt repeatedly snapped or popped right off. Pulley was froze and wouldn't allow belt to roll it when tension was put against it.

I'll make sure I take some wd-40 or something when I go to see it Saturday.

OK. just chatted with the guy and he said the previous owner told him the clutch hangs up. He said the pulleys are all free and he has bought 7 belts, now selling it. Does this sound like something repairable or something requiring new parts?

not really any way to tell unless you take it all aprt, as the part that make the clutch work right are all behind it. There are washers and ball bearings in a cup that lock up over center. Sometimes people who didnt know how to repair one put in some in some odd ball parts. I dont think your going to get hurt, as there are fairly simple to fix with the right parts and there are some out there yet.

yea theres a large spring that pulls down on the clutch. Theres gotta be 100 of em on ebay right now for bout $10. Just seen them the other day. If its the spring thats not allowing the clutch to retract then it could be an easy fix. See i knew there had to be something hangin up, clutch stickin really isnt any different than a pulley freezing, essentially its still not allowing the belt to move freely as should. Part that concerns me is that this guy has bought (7) belts without fixin the problem....... :bigrofl:

They were called 725 because the Briggs model 19 engine produced 7.25hp. They were made 1963 and 1964. In 1965, they switched to the Suburban 8 and 10, with Tecumseh HH80 and HH100 engines respectively. In 1959-61, the tractors were gold and blue with rounded hoods, and in 1962, it was a baby blue tractor with the round hood. The 725 in 1963 was the first of the sqaure hood tractors.
