• John Deere X500 Service Manual

I purchased the X500 with 48' mowing deck and it is very good. Has the Kawasaki v-twin FS730V engine, a diff lock (when required), very easy to check and adjust the mower deck level and is a real workhorse. Very easy for women to use & operate if you are wondering. Owners need to be aware that John Deere issued (2) Operator Manuals for the X500 models manufactured in 2014. Check the PIN (product identification number) on the front left hand side chassis of the machine and then check with John Deere Australia (AU Freecall: 1800 800 981) that the correct Operators Manual has been issued by the dealer. The difference between the Operators Manuals is the types of transmission oil that can be used - only John Deere Low Viscosity Hy-Gard (JD20D) can be used in the earlier 2014 Operators Manual.

The later 2014 Operators Manual specifies John Deere Hy-Gard (JD20C) transmission oil or John Deere Low Viscosity Hy-Gard (JD20D). Critical that owners check because affects the warranty for the transmission. I was sold on John Deere.

But for the past three years the 54' machine has been back to the dealer two to three times each mowing season to adjust the deck. It lasts less than two hours and continues to cut uneven.

The yard looks like a test strip for a bad mower. The dealer's maintenance people have no idea what is wrong. They say they have check with JD and still no answer. I have asked to replace the deck and see if that is the problems, but of course that has not happened. At the end of this summer if it is not corrected and running properly, I will get rid of this machine.

After paying $5000+, I expected more from the product and the dealership. I have owned a John Deere LX280 with a 42' deck for 6 years and thought it was a really well built, strong ride on. The 18hp Kawasaki twin engine was superb. However I finally decided to get a new beast and after much consideration and research, I settled on the X500 Multi-Terrain garden tractor with a 54' Edge Extra deck - and what a beast it is! It has a 26Hp Kawasaki twin engine that is superb - smooth, reasonably quiet but boy does it have some grunt. And the deck has a higher capacity than the 100 series Edge decks and has much heavier blades.

It has a through the deck level adjustment that make it so easy to adjust. And the tractor, with diff lock when needed, is even better than the LX280 to drive.

It is smooth, the steering is easy and infact has more turn than the old LX280, and the auto gear box is a pleasure to drive. I would recommend this tractor to anybody - and I know. I have a 55hp tractor with a 6' HD slasher for the paddocks, but this is almost as capable - well it is certainly more fun!!

And as an add on - I am putting Gator G6 mulching blades on it, a fixed Bumper, and a LED reversing flood light to complete the package. If you want the best, and aren't into those zero turn toys, this is about as good as it gets.

Put a drain pan under fuel filter. IMPORTANT: Avoid damage! Using incorrect coolant mixture can cause overheating and damage to the radiator and engine:.

Do not operate engine with plain water. Do not exceed a 50% mixture of coolant and water.

Aluminum engine blocks and radiators require approved ethylene-glycol based antifreeze. The following John Deere coolants are preferred:. COOL-GARD® PRE-DILUTED SUMMER COOLANT (TY16036). COOL-GARD® CONCENTRATED SUMMER COOLANT (TY16034). If neither of the recommended coolants is available, use a glycol base coolant that meets the following specification:. ASTM D4985 (JDM H24A2). Check container label before using to be sure it has the appropriate specifications for your machine.

Use coolant with conditioner or add conditioner to coolant before using. If using concentrate, mix approximately 50 percent antifreeze with 50 percent distilled or deionized water before adding to cooling system. This mixture will provide freeze protection to -37 degrees C (-34 degrees F).

Certain geographical areas may require lower temperature protection. See the label on your antifreeze container or consult your John Deere dealer to obtain the latest information and recommendations. Never exceed the maximum dilution rate for the coolant you are using. Exceeding the maximum rate will greatly reduce the coolant effectiveness.
