L4310D 4WD: Sorry to ask such a dumb question but I'm new to tractors and I don't have a Op manual.
On the rear chuck ( not sure what its called but it has the small glass window ) above where the pto is has the window to check fluid. Do you check the level when the tractor is running or off and what type / weight is used. The fluid level is showing half way up the window with the motor not running. There is an orange screw on cap on the top half to add to this area correct ?
Again sorry for this type of question but I wanted to make sure before using the tractor for the first time.
I have checked the oil level and coolent levels.
Thanks for your help

I think you are referring to the "sight glass" for checking the hydraulic fluid level. There should be two horizontal lines on the glass or the white background. The fluid level should show between those two lines with the tractor not running.

The large orange plug in the rear is the likely fill point. Nothing else in that area needs to be poured in.

The fluid is termed hydraulic oil or hydraulic fluid. It is a special oil for use in hydraulic systems. It has to be purchased and used separately from engine oil. Two completely different products.

Almost all tractor dealerships have their brand of hydraulic oil - Case, New Holland, Kubota, and others. Tractor Supply, and even Sam's Club, sell a cheap hydraulic oil that is best avoided unless you are dead broke. It will work in a pinch.

Since you don't have a manual, I'd guess you have a total hydraulic reservoir holding around 7 to 9 gallons. Hydraulic oil comes in 5 gallon buckets so a couple of those should do your next change with a bit left over for leaks.

The good stuff runs about $70 to $100 per bucket. Sam's oil is $49 per 5 gallon bucket if I remember correctly.

GWD,
thanks for the information. I will stop by the local Kubota dealer tomorrow and pick up some hydraulic fluid. I did not see any lines in the window and it just looked like a white background. I did look again and the fluid is at the very bottom of the window just hard to see.
Thanks again

Fluid level should be in the middle of the sight glass. It should not take much to bring yours up, a quart or two at most.

When you check the oil level have the tractor sitting as level as you can. It doesn't take much lean in any direction to make the oil go from low to normal to overfull depending on how it's sitting. In most cases if you have oil in the glass you're good to go. Your dealer should be able to steer you in the right direction on the oil. If you do go to look for aftermarket fluid it's tractor transmission/hydraulic fluid not just plain hydraulic oil. In most cases you can use trans/hyd oil in any hydraulic system but you can't use hydraulic oil in a transmission.

Thanks for all the replys,
Only took 1 qt. after I moved it to a level part of the drive. As far as motor oil is 10-30 what most run in the South.

I use 5w30 synthetic myself. Makes a huge difference in the winter. You don't need 15w40, all it will do is make you burn more fuel.

The oil used in a diesel engine must be rated for compression ignition. It should have a "C" at the beginning of the rating. Like "CJ-4".

I use 15w-40 engine oil in hot Central California. Diesel consumption is not much of a factor unless the tractor is used commercially for 10 hour days and then days on end.

If you have a Costco nearby, it has Chevron Delo 15w-40 on sale with a coupon. Just bought three boxes (coupon limit) yesterday.

x2. Make sure that you do not put gasoline engine-rated oil in your diesel.
