Do you mean instructions to operate or repair manual?

You can get a basic workshop manual for not too much money. For the OP's you might have to trawl the likes of ebay. Is there anything in particular you need to know? They are fairly simple to operate. Is yours a straddle cab with the trans tunnel or have you got a flat floor? Either way the controls and service are near enough the same. A few things that come to mind:
Is there a 2 speed shift on the left hand side of the steering?
The PTO has a feathering position, don't hold the leaver in the feather position or you will damage the PTO hydraulically operated clutch.
If you have a work handbrake be careful not to allow anyone to drive it with handbrake applied. They are crap and very easily driven off with one on and damage rapidly.
Let the tractor halt properly shifting on the range/reverse leaver. When worn it is easy to get the linkage jammed. If a ta (2sp shift) fitted sometimes shifting to low helps a shuttle.
If there is a working TA try not to use unnecessarily and don't shift to low to aid braking down hill as that can damage the unit.

Hi Pete
Yes i do have to straddle ,with foot either side,
There is a lever on the left hand side of the steering wheel.
Handbrake does not get used,
which levers on the right hand side of seat are for the PTO.
What is a TA?
regardsJack

The lever to the left of steering wheel is the TA torque amplifier or 2 speed shift. In a nut shell a hydraulic clutch pack controls planatary gear in the front end of the transmission. You will find out if it works by driving in a low gear and moving the lever forward or back. The unit can be troublesome with high hours or careless use.
The levers to the right of the seat that have a long movement are the position/lift control for the 3 point (nearest seat) and draft control. The draft control needs to be pushed forward and down when using mounted equipment requiring height control rather than soil engaging like a plough. Behind the main levers you will find 2 more short levers. The one with the staggered quadrant it the PTO the other is raise response when using draft control. The PTO lever should be engaged with engine revs low smoothly through the feathering stage in to full engagement. As said over feathering, whilst being kinder on the driveline and driven machine, will result in premature wear of the PTO clutch pack. Ahead of the main three point levers you may have a spool valve or two for remote hydraulic services (by your right knee). If you have the stop lever in the middle above the transmission tunnel, that might have a cold start position in the middle between stop and run.
Service wise you will find an oil filter and 2 fuel filters (both spin on) and a transmission filter on the near side transmission behind the lh back wheel. That has a strainer as well and mut not be over tightened with a new o ring. A pipe union adjacent should also be partly released to bleed air after filter change.
I must admit I have not done the latter.

Bloody hell Pete ,,you just wrote a manual,,thanks Pete.
I have just one more question,, there is a little pedal/lever at the right hand side floor,,that looks as though it has to be operated by the right heel?
and yes the cut off switch is in the middle above tunnel.
Regards Jack

The pedal you operate with your heel will be the diff lock. Might be seized.
