Did a little more work on the Cub today...
The brakes were a little weak, found out how to adjust them (really easy) so I tightened them up.... it'll now lock up the 26" ags on the concrete... stops much better, and the brakes are quite useful now.
I changed the transaxle fluid... I was reading a thing that said 90w gear oil, SAE30 engine oil or ATF, it dosen't matter, the gears are extremely hardened and really won't break, so I was going to go with SAE30 motor oil... getting the drain plug removed was a pain, I don't think it was ever removed in 45yrs, to get more room I got the ramps I use for the car and put them behind the rear tires, then put it in reverse and with the ignition off, bumped the starter to starter-drive it backwords up the ramps... heh.. that didn't phase the huge Delco-Remy starter-generator one bit as it turned the engine over, which was in gear, thus drivign the tractor backwords, up the ramps, at the same speed it normally turns just the engine over

Thats whats great about being overbuilt.
Finally got the drain plug removed, the old fluid was rusty looking, 3-1/3qts came out... from the red tint, the smell and consistency, it looked like ATF, which worked out well as I have alot of Dextron/Mercon here, so I put ATF in it.... too about 5qts until it started to come out the fill port.
No noticeable difference maybe a bit smoother, but alteast it's changed so thats good. Then I got the Seafoam spray and sprayed it into the carb while it was running at about 1/3 throttle, then let it idle and stalled the engine with the seafoam, let it sit for about 15mins, then started it up...lotta smoke, but get it cleaned out nice
finally I used it tonight to tow the Isuzu to the end of the driveway, my driveway slopes toward the road slightly, so I rolled the Isuzu on to the driveway stright, set the parking brake, backed the Cub up, tied the truck to the tractor with the tow strap, right at that time my friends came over, so I had one get in the truck to steer it and apply the brake. With the Isuzu rolling free, the tractor was in gear and engine off, I got on, hit the brake/clutch, the tractor brakes were holding everything from rolling without a problem... put it in first, started it up, only about 1/3 throttle, slowly let the brake/clutch out, brake released, rolled back a little, then the clutch started to grab, stopped rolling back, let the clutch out a little more... little too fast tho as the tires chriped a bit, let the clutch out all the way and it just chugged along at about 1/3 throttle as if there was nothing hooked to the tractor.... that was pretty cool

It was fun to use the tractor for work
So the Isuzu is now at the end of the driveway, out of the way, but most of all, on the concrete so I can start to rebuild the enigne to get it running again.... that'll be fun.
