M7060 Air Suspension Seat not working

[dhcole99]

Air ride seat no longer does anything. Before I start investigating any suggestions to troubleshoot? My first thought is to check electrical. Tractor has 1400 hrs.

Check fuses, then wiring connectors, then wire continuity and grounds

Thanks. Ok. Will let you know what I find.

It does sound like an electrical issue. If all of those items are ok, I'd look at the pump to see if it's working. A hole in the air bag seems unlikely at this stage since nothing is working.

Have a tough time troubleshooting the seat. Part number is Kubota M9270 or GRAMMER DS85H/90 but cannot find any diagrams or parts listing. The diagram in the Kubota Canadian Parts site does list the seat and the diagram is terrible and difficult to make out what goes where. Any idea where to find a parts list or diagram?

Issue ended up being a failed switch. Unfortunately a replacement switch is $500+ CDN. Way too expensive for me so I added a $1 rocker switch to tide me over until I figure out next steps. Any suggestions for a better hack or how to fix myself would be appreciated.

Nice job figuring out the problem! You could contact Grammer and see if they'd send you a replacement switch under warranty. Maybe worth a try.

Another option would be to find one on Ebay or similar. There appear to be plenty of them if you search under Grammer seat switch.

Read all the small letters and numbers on the case of the switch.

Then search on the internet for the part number or size of the opening.

Look at Mouser and other similar vendors online for the switch with whatever vendor name or numbers you can find. Order several of them since they will be pretty cheap unless they are something unusual. You may be able to get it “upgraded“ with engraved letters or symbols if you want to and can figure out the vendor codes.

Right idea. I haven't looked at mine is there a microswitch in the seat somewhere under all the tupperware?
