Oliver 77

[Herald P Ia]

Friend has a nice "77" 1953 model. Wants to know is it possible to add hyd. on it. Would like to run his haybine with it so a PTO pump would not work. Also, can you tell by the serial number what options were on it. Thanks. Harold

You can put a hydraulic pump on it in place of the manual cultivator lift with a little modification. Back in the day,a neighbor put a self contained unit like you would put on the PTO on a piece of pipe where the cultivator pipe goes and ran it off the belt pully hub. He made a sprocket to bolt in place of the pulley and ran the pump with a chain. He'd just shut it off when he wasn't using it. Wasn't live was the only problem.

I would think if a 1953 that it should have had hyds on it but maybe that was an option and who ever got it in the first place did not want hyds. My 1950 77 has hyds and so did the other 77 I had that I sold. Should be a plate where the hyds should go which would be below the steering column and behind the brake pedal cross rod. If there is a plate there it would probably just be a matter of finding a hyd unit to install but to do so the PTO has to come off to slide the shaft into the pump

It must have been an option. I have a '54 77 that I bought from a fella whose Dad bought it new with no hyd. or mech. lift. Said He bought it for field work. It does have a pto on it though, so I guess I could put a unit on it.

I bought a Super 77 one time that only had the cover. I bought a pump from the bone yard and put it in that one. I didn't have to modify anything,but if it has a mechanical lift,I guess there's something in there that has to be ground or cut off. Don't know personally,but I'm sure somebody who does will say so.

you can add a pump to it fairly easily. we did the same with our 88 standard. however when we did the 88 it had just a cover and we found out that the shifter is a different design between a plate and a hydraulic pump and i am not sure if there is a difference between a rollamatic and a hydraulic pump so stick with the shifter that came with the pump. to install it you need to take the pto clutch shaft out then add the pump to the tractor then put the shaft back in. wish you luck.

Herald, if the tractor never had a hydraulic the input shaft will have to be cut so the pump will fit in and the pto support will have to be removed. the input shaft can be cut without removing it from the tractor. you will need a good carbide blade to cut it.I may have a good hydraulic unit for sale , if i don't hear soon from the gentlemen that said he wants it, chuck

We used to cut them off with an old broken power hacksaw blade. Hold the blade with a good vice grip and let the engine idle as slow as possiable and saw away.

OT - Will send you an email update. Winter theives got to my 1650. Still wanting hyd.

I tried converting my mechanical lift to a hydraulic unit. Had to ream out the hole of the shifter & cut the gear in the transmission. It's not a hard thing to do. However, the problem I have ran into is finding a pump that is good & not breaking the bank. I have the top unit, but no pump. Anybody got a good pump for a reasonable price email me.
