Show us your filter magnets please.

Just did the first hydraulic filter change on MX4700 with manual transmission. Owner's manual states 400 hours but I decided to do it a little early at 200 hours. Cutting the paint at the seam helped a lot, filter came off no problem. Fluid shows glimmers of very fine shavings but not extreme. Probably would have been better to change the filter at 50 hours but was going by what manual says. I noticed a couple of larger chunks on the magnet and wanted to compare to what others have found on their magnet after the first filter change. I have attached a couple of photos of mine. Not sure if this looks normal??

Would appreciate if others would also show some photos of theirs!!

Thanks in advance!!

Magnet is only an indicator, cut your filter open and look at what is being caught. If you have metal in the filter paper you need to figure out why.

It's not the large heavy stuff that the magnet catches that you need to primarily worry about, it is the metal if it is circulating in your system.

As it is a new tractor, likely that is just manufacturing flashing on gears and break-in wear on your swash plates etc. The filter element should be pretty clean. If not you may want to consider send a sample for analysis to find out where it is coming from.

I wouldn't have a minute's concern seeing that after the initial 200 hours.

A transmission specialist once told me that every transmission will have some metal in the oil. No way to avoid it he said.

M7060. @500hrs, first change as per the manual. (I bought it used)
Filters inside were fine, a bit of rubber gasket goo stuff. I rechecked them after 50 hours and found very little so likely leftover manufacturing bits, so the dealer says.

I changed my filter at fifty hours per the instructions. There were some metal shavings trapped on the magnet - not a lot. I was expecting a few after speaking with the local mechanic. It never occurred to me to take pictures.

Hey, I didn't see any magnets, just filters with shavings on them, did I miss something?

Yeah, you missed buying a Kubota.

From the era when Kubota stopped cleaning out the drillings and machining debris. Tractor has run a over decade since w/o trouble but it was scary when I first saw it !! These are Hydraulic filters.
