Kubot B2100 won't start

[windowman]

I don't have any current to the starter. My battery is fully charged. When I cross the terminals on the solenoid the starter spins but doesn't engage. Any ideas?

Thanks

I'm not a Kubota expert, but if you cross the terminals and the starter spins, the the one terminal is hot. Are the connections at the starter tight and clean? If the starter spins but doesn't engage, it would be a solenoid problem, if you are crossing the proper terminals. The solenoid is not pulling the starter gear to engage the ring gear on the flywheel. If the starter won't spin when using the normal start switch, then there is a problem in the start circuit ( including any related safety switches) or switch.

The solenoid is what brings in the starter, so either the soleniod is bad but most likely a safety switch is not making. If the starter is not engaging when the starter spins the there is a problem with the bendix on the starter itself. Bendix should engage if starter spins, maybe there a burr on starter shaft that stopping the bendix from moving. Hope this helps

Thanks for the help.

On my old Kubota, I had to adjust the clutch safety switch a couple of times over the years.

I got my Dad's 9N fired up. The starter would not turn. It was a bad/dirty terminal connection at the starter.

I would double check all the safety switches are working; Sitting on the seat, clutch in, tranny in neutral, PTO disengaged, brake on.

After that, I check voltages and make sure all the wire connections are bright, clean, and secure. That includes the battery cables, at both end. Give the ground connections particular attention.

Dirty grounds can cause endless frustration...
