While you have tank exposed put risers over the ports and bring them up to grade and put lids back on .

Noo! Many, if not all old septic tanks are steel tanks. They are usually rusted to the point of collapse after 25-30 years. As said, spread out timbers that will span beyond the width of the tank. Do not run the machine over the fields either unless you are replacing the entire system.

The OP describes the tank as being about 4" thick.
Quite obviously it is a 4" concrete tank.
That would be one hxll of a steel tank if it were 4" thick.

And not running g a light b series even over the field????

How do you guys mow your leach field?

My house was built in 1987. I know where my tanks are because I have risers. I have no issues running a 8000#+ mx Kubota over it.

Not entirely sure where leach field is, but I am pretty sure my 18000# backhoe has crossed it several times.

I have went over ours every week for the last 10 years with either a B or BX when mowing. I have crossed over it with a MX5100 well loaded with out issue several times.... Ours is about 3' deep in well compacted soil.

Is it the pipe from the house to tank , or the field not draining ? You need to uncover the tank and the lids and see what is going on . How much paper is being used ? If it is the pipe from house to tank , easy fix . If not ,$$$$ . I am going to wager that thinwall PVC was used on the system and has settled or snapped off at inlet or outlet .BTW you need a new pumper guy !

This is basically what he said Kevin.
My system stopped flowing. I phoned for a pump. " He's been in the business installing tanks and pumping for 50 plus years. The 2nd or 3rd gen owner " When we pulled the caps off the tank, the level of sewerage was several inches below the sewer pipe outlet from the house. ( Way below the inlet Pipe )
He pumped the tank out and asked me to go in the house and run all the faucets and toilet.
Nothing came out of the pipe, still backing up.
He retrieved a Snake and ran it into the inlet pipe to the tank.
It kept getting snagged, hitting something.
He finally got it,, Everything flowed out in within several seconds.
His Snake was hitting against something. The snake had a roller ball on it and was still getting snagged up.
Funny,, He laughed. It's time to take that pretty waxed up new Kubota of yours out of the garage.
Dig out this 10' pipe coming from the house to the tank. Phone me back when you're done.
Something is going with that pipe coming from the house to the tank.
He said don't worry. I don't think it's split and leaking into the ground.
Most likely it has a Divot in it... Bent down, to the side etc.

It can actually be helpful, if one reads and understands the OP posting, before offering a response.

I will not offer any tips on how much weight is too much weight on a concrete lid. My only memory is the duels of a fire engine look really stupid in a septic tank. Don't ask me how I know that...

I have seen a skidsteer swallowed up by an old tank too.....
