Hello Folks,
I'm hoping someone out there has an IH 3414 with a hydrostatic transmission that can help me to understand what about my transmission is correct and what is not.
The tractor has a 4 speed (I believe) transmission. There are also 2 pedals on the left side, one for forward and one for reverse.
The linkage is very sloppy, so I will be working on fabricating/repairing the linkage parts.
Currently the tractor will not drive forward unless the reverse pedal is lifted up on. I think this is due to the slop in the linkage.
Question 1, what configuration does the tractor need to be in to shift gears in the transmission? Currently, the only way I can shift is if the tractor's engine is stopped. If I try to shift while running it grinds gears. Both pedals can be depressed simultaneously, so I assumed that was to disengage the transmission so it could be shifted, but doesn't seem to work.
Question 2, should the tractor stop and hold position when in gear, running and neither pedal depressed like the hydro on a lawnmower? Currently, as soon as the pedals are released the tractor freewheels.
If the tractor is on an incline and driving forward, as soon as the pedal is released, the backhoe will roll backward rather than holding position.
Question 3, does the hydro use the same hydraulic fluid from the tank in front of the fuel tank, or is it a separate system?
I currently have moisture in the system (milky fluid) that I plan on flushing over the next week.
I would love to pick the brain of somebody who has one of these tractors with the hydro transmission!
I haven't located the data plate yet (it might be gone) because it is not on the right bell housing as it should be. So I don't know serial number, and therefore year.

Today's Featured Article - The 8N and the Fox - by Zane Sherman. Dec. 13 1998, Renfroe, Alabama. Last niht I dreamed about the day that I plowed the field of about 10 acres over on what Jimmy and Dandy called the Ledbetter field. I was driving the 1948 8N Ford tractor that Jimmy bought in 48 new This was prebably in about 1951 and maybe even befor the house was built. This would have made me to be about16 years old and I drove the tractor for nothing and would have paid to drive it if I had had any money which I didn't, but neit
