1886-01

The 1886-01 the production run of the 1886 was built in 1971 and only for that year. It was later replaced by the 1886-02 in 1972.

Here are some ways to tell it’s an 1886-01.
1. There is no cut out for the oil filter.


2. The 1886-01 is the only production run with the pull choke and throttle.


3. The PTO lever is a cast round piece you push down to engage.


4. The 1886-01 seats have a leaf spring for cushion.


5. The 1886-01 has the Eaton 12 for its rear end.

1886s-05 HT18

The last 1886 production run built in 1972, and the first to replace the Eaton with the new Sundstrand 15 hydro. The 1886s-05 stayed with the off white and brown for the paint scheme.

5. Bolens added an oil pressure gage to the dash tower above the hydraulic levers.


6. Bolens added a light to the dash tower to tell you the hydro was to hot. It’s located to the left of the oil pressure gage.


7. Bolens replace the Eaton 12 with the new Sundstrand 15 hydro.

The brake pedal location is the same on all the 1886s and the rest of the large frames. The brake pedal is located next to the hydro control pedal. It would also be on the right side if you were sitting on the tractor.

Same side yes,but the later ones I'm sure had the pedal 2 or 3 inches to the rear,like on the HT-20.

Ok so which is better? The Eaton 12 or The Sunstrand 15? I have heard the Eaton, but didn't the Cub hydros use a Sunstrand unit? Tough as nails as well?

Great information, now if I could just find one near me at a reasonable price. :praying:
