I inherited my dad's 1976 model 800. If I counted the tires & belts, there MIGHT be a dozen rubber/plastic parts. All the rest is iron.
Do NOT put anything but Hy-Tran branded fluid in that transmission. Nothing else meets the specifications.
A few farmers found that out the hard way on their big 1026 Farmall tractors using some reddish-orange fluid that looked more like the original GM brand "Dexron", then howled when IH turned down their warranty claims, and they had also used knock-off hydraulic filters.
IH built those vintage Cub Cadets with the same ruggedness and care as the big Farmalls. Think of the Cub Cadet as a Farmall Cub that was washed in hot water......
