well just some food for thought
fluids/oils go bad from TIME alone, NOT just hours of use
SO< after "X" amount of time its recommended to replace them, same with filters
and as for implements
brush hog.mowers, can be very HIGH demand on GPM"S, so pending size and design of the brush cutter you have, you maybe at the max or past what you machine makes(they make both high flow machines and low flow, as the same with brush hogs, and its not that un common for folks to buy the wrong implement for the machine they have, happens all the time)
which would for sure be a cause of high temps, and doing so for long periods of time can harm your machines pumps and hydraulic system, leading to very costly repairs(not saying your doing this, just saying what it can cause if your using implements needing more GPM than your machine makes, or even at its max ,)
SO< knowing what your machine makes and what your implements require is important info to have,
once a oil is hot too many times it looses its ability to cool properly and lubricate as it should, which again can lead to failures on pumps, wear and tear on moving parts, or even again total failures!
Hydraulic hoses too, go bad from AGE and time,
all the more so those exposed to UV and or flex alot or rub things, hoses move while flow is going thru them , so many will wear holes into them from this alone
and when a hose fails they can be very dangerous
so its always good to inspect them from time to time, and look for signs of aging or wear and tear
drying, cracks, spots where outer layer is damaged and so on!
NEXT even if you had the dealer change all the fluids 4 yrs ago, when they DO basic draining of fluids, they NEVER get all the old fluids out, due to the hoses hold a LOT of fluid and most do not all; drain empty, so there will always be OLD fluid left in the system that will mix and make new fluids look dirty once using it not as dirty looking as ALL old fluid, but will cause new fluid to loose its clean color!
it also would NOT be the first time a dealer claimed to change fluids and NOT do it (I caught a dealer doing this not so long ago,$1,010 bucks for service they never did, so this happens more often than many may think it does)
but even at 4 yrs old, it would be recommended to replace on just time that past and NOT use, pending how you feel about recommended things, MOST new diesel machine require a once a yr oil replacement to keep warranty's, no matter how many hrs, they go by "X" hours, OR "X" months of time, which ever comes first
so at 4 yrs>?? your machine,your money, your call!
just once again giving food for thought!
last food for thought is, also if your doing a lot of brush hogging, I HOPE you have a safety door, that will protect you from flying debris, and NOT just a glass door, they make special doors for brush work, because things can fly back at the operator and do serious harm or worse if things go wrong!
yes folks get away with NOT having them, but there is a reason they make them, as I said, food for thought, NOT telling you what to do or things will happen!, just adding info for you to think about
