Off-Road diesel fuel is very similar, although not the same as on-road fuel. Its easy to pick out off road fuel because its dyed red to indicate that taxes have not been paid for road use. For an end user it is important to know what additives are in either fuel. Its usually necessary to be adding additives for gelling and sludge removal. Off-road does have the benefit of having higher sulfur content than on-road fuels, this is being continually reduced to improve emissions however its at the expensive of lubrication. All of these conditions can be corrected with the liberal use of fuel additives. You will be hard pressed to get a straight answer regarding off-road fuel out of any company, however no one seems to be reporting known adverse effects.
Many tractors with hydrostatic transmissions have two filters for the transmission. They are actually filtering the same oil and work in the same part of the tractor. A separate filter is used specifically for the hydrostatic drive because the system works in a loop sometimes circulating as little as a half gallon of fluid at a time. The second filter ensures that this small loop does not become contaminated since it does not regularly mix with the rest of the transmission fluids.

Often times front axle housings are filled with the same fluid that the transmission is. This is perfectly acceptable as a good quality fluid is used from the factory. When changing this oil consider upgrading to an 80W-90 weight oil. This is suited best for use in heavy duty gear boxes.

When draining this oil make sure that you check for multiple drain plugs, and when filling leave time for the oils to settle down into the lower regions of the gear boxes before topping it off.
When cold starting a tractor the glow plugs can be more effective if you turn the tractor over for 2-3 seconds before warming the engine. Once this is done raise the throttle to about half to get more fuel into the engine. This helps pull more fuel into the engine just like choking does on a gas motor and will make starting easier.
Hydrostatic transmissions often make noise when the hydraulic fluid is cold and stiff. To help things warm up and operate more smoothly simply put the transmission in neutral and press the hydrostatic pedal. This starts the fluids moving (even though the tractor is not). After a few minutes things should be loosened up nicely and operation should be more normal. Using a high quality transmission oil can also make a substantial difference here.
Summary: Either is often used to help start engines. Over the years we have learned that its not terribly effective. A good alternative is to crank the engine until if puffs white smoke. Then use your glow plugs and crank again. Repeat until the engine starts. The opinions expressed here are that of the individual and not that of Messick's or the companies we represent. Please consult your owners manual for the most accurate information.
Summary: Its usually best to remove the loader from a tractor when doing tasks that don't require it for use or ballast. Doing so has several benefits. It removes weight from the front tires making the tractor easier to steer, makes the tractor lighter reducing ground compaction, and greatly extends tire life when using 4WD. Most modern loader are very easy to remove and some larger machines even have quick attach buckets that can be quickly dropped off the tractor.
The air filter is your main line of defense against dirt and debris. It should be checked often, almost daily depending on conditions. A little known feature of many newer air cleaners is that the rubber piece on the bottom of the cap can be squeezed to release any large pieces that have collected in the trap. It is possible to try and clean air filters, we recommend not doing more than simply knocking the filter on the floor. Chemicals should not be used, nor air pressure. Its simply too easy to damage a filter and subsequently destroy the engine.

Chart is for a gallon of water weighting approx 8lbs per gallon. Water is not a typical tire fill. Methonal Alchol is a more common fill and weights 6.5lbs per gallon. Other fills like Calcium, Beat Juice, etc can be varying weights.
