I have a MF-65 Diesel and would like to add a hydraulic cylinder to the top hitch point on the 3 point hitch to tilt a box blade with. Does anyone know what size cylinder will fit the 65?

just measue the standard top link eye to eye you have on your mf65 tractor, this is the length of you hydraulic top link.

There's products out there called "top and tilt". They put a hyd cyl on the top and one side of your 3PH giving you full hyd adjustments.

Here's the first one that pulled up in an internet search.

G'day JAKA.
To do what you want to do you will need :
A hydraulic selector valve, buy the PUSH/ PULL TYPE ,this valve is made to fit Massey tractors only.
A dual hydraulic spool with one Double acting spool and one single acting spool.
Hoses. I use 3/8 inch hose ,no smaller.
A toplink double acting ram.A ram with two inch cylinder and say one and a quarter ram will do,to measure the ram length set the box blade on level ground and measure the length of the toplink ,centre to centre of the eyes ,you want the ram to be MIDSTROKE this will ensure that the ram can give you travel in BOTH directions.

The ram , dual spool and selector valve can be bought from ,
www.ssbtractor.com or Sparex ,bareco,vapormatic etc.
The hoses can be either purchased premade or made to order locally.

Under the seat there is a transfer cap ,it is on the lift cover, that is the hydraulic cover that the seat fits onto,front right hand corner,it is about 3 inches by two inches held on by two bolts.
Important : Before you remove the cap lower the hydraulic linkage ALL THE WAY DOWN
This will drain all the oil from the lift system and avoid injury also minimisling the mess on the shop floor.

Remove the cap and install the selector valve, when you remove the cap there is a Hydraulic stand pipe which either sticks out of the lift cover or is attached to the cap ,it is about 12 inches long ,if it comes out with the cap ,remove it from the cap and replace the "O" rings on BOTH ends,to refit the standpipe remove the sidecover that is the one on the right hand side of the gearbox with the dipstick on it,remove the cover ,lower the Standpipe down and with your left hand guide it into the hole in the top of the hydraulic pump,if you want to make sure it is in the correct spot,PULL OUT THE ENGINE STOP and place the lift levers ,draft in the up position and position in the transport position then crank the engine a little bit say two turns of the engine, if you get oil on the shed floor this will tell you two things,one the pipe is in the correct spot and two you cranked the engine to long.

Next fit the cap,the outlet of the cap is 3/8 npt /bsp thread .
Mount the spool valve the same place as you would when fitting a front end loader,somewhere comfortable to operate,when it is mounted in your place of choice,connect the supply hose from the selector valve that you fitted, to the SUPPLY on the spool valve.

the return hose can either be fitted to the transmission filler cap or under the seat ,left hand side about where the FRONT seat mounting stud is ,you will find a 3/8 inch npt allen grub screw/plug in the hole,remove the plug and fit the return hose from the return on the spool valve it will be better if you install a 90 degree elbow into the tractor ,it keeps the hose neat.

Important :Fit a hose from the SINGLE ACTING spool control port to the front left hand side of the lift cover ,you will find a plug the same as the return oil point plug,remove it and install the hose it is important that you connect to the single acting spool.

Fit the hydraulic toplink and connect the hoses so that it is logical when operating that is, pull the lever back to tilt the implement BACK or away from you,when you use it you will know what i mean .

The spool valve will when operated give you EITHER CONTROL OF THE LINKAGE or HYDRAULIC SUPPLY to the spool control valve,not both at the same time.

Next connect the implement of your choice and with the hydraulic spool valve in the IN position you can use the linkage as normal .

Pull the selector valve OUT,SET THE HYDRAULIC LEVERS IN ,one DRAFT all the way up
and POSITION control lever in TRANSPORT, THIS WILL NOW GIVE YOU CONTROL OF THE HYDRAULIC SYSTEM FROM THE SPOOL VALVE ,INCLUDING THE LINKAGE.
Example to raise AND lower the linkage operate the lever and the linkage will be raised and lowered as you would using the hydraulic control quadrant on the tractor the only thing it wont do is give you draft operation it will only raise and lower the same way as when you are using the POSITION Control lever.
The other lever will give you control of the toplink,example pull the spool lever towards you and the lingage will tilt Away from you.

To return to normal operation reset the Selector valve under the seat and you are back to normal operation.
You will find it a lot easier to fit quick disconnect couplings to the hose ends ,it is much easier than unscrewing hoses and a lot less messier,just remember if you do ,before Disconnecting a coupling lower the linkage to the ground ,make it safe by operating ALL levers with the engine stopped this will make sure there is no trapped hydraulic pressure,.
If you were to disconnect a hose with pressure still in the hose the coupling will be under pressure and you will find that when you come to reconnect the hose it will not reconnect because the pressure is holding the coupling valve closed,if you find yourself in this position ,get a bolt that fits inside the coupling ,put the bolt in the end of the coupling ,wrap a rag/cloth around the whole thing and give the head of the bolt a reasonable tap either on a piece of wood or with a hammer ,not to violent you are only pushing the small non return valve ball back to let the trapped oil out.
That is all you need to do.
Note if you want to add a TILT ram to the linkage .
Remove the linkage levelling box and fit a hydraulic ram in its place make sure you get a ram that will allow you to tilt the linkage BOTH ways that is dont fit one that is to long otherwise it will not have enough travel ideally you want a ram that is MIDWAY in the travel and the linkage is LEVEL,of course this will mean you need a THREE spool valve connecting the TILT the same way as you did with the TOPLINK.
Easy.
Happy Days.
Hutch.
