Hi all, I bought this machine last year running but in need of drive sprockets.It has an 18 hp air cooled 4 stroke electric start engine. 2 speed gear box with reverse and a Salisbury clutch system. 1st gear 8mph and 2nd gear 18mph around a 1000# payload and 1500# towing. They seem to be a well built all terrain vehicle I'm told was and still is used in the Canadian oil fields. You can still buy parts and they will even build you a new one if desired. I have enough replacement parts to keep it going for ever. I plan to keep it at the cabin in a container to play with up there also for emergency if something won't start or whatever. So far I have cleaned , painted and greased the under carriage parts. Polished the tub and painted the inside with bed liner. Now its time for re assembly. This is a project I work on between other projects like the work cabin. The tracks are 96" long and 17-1/2" wide X2 = 3360 sq. inches and the machine weighs 1500# that works out to .44 PSI dry. thats pretty good considering my Tucker is .68PSI the previous owner said he never had it in snow he mainly ran it off road in the desert and the Rubicon trail here in Ca. Now it will be a mountain cat not a desert rat. The tracks are in good shape as well as the grousers. I will post as I go. Marty

So today I put the new drive sprockets on the drive hubs. ( not fun ) they are about 1/16" small all the way around and have to be worked on. It reminded me of when I was a kid on the farm changing tires on and off rims with a bumper jack, a piece of flat bar and a hammer. they took about an hour each to slowly work them on the hubs. Also they are an inch wider than the old ones so I will have to get longer bolts. Marty

Thanks, its a project I work on in between projects. I am in the middle of re powering a COOT right now. I'm getting caught up and will get back on the raidtrac after Christmas. as for hydrostatic I just ripped an arrangement like that out of the COOT. The problem is there is not enough variation of speed and torque. It would kind of work but wouldn't climb steep hills or go over walking speed. The 2 speed transmission with the Salisbury clutch works much better.
