I said it before and this thread and I’ll reiterate - I highly doubt a ‘95 has any parasitic draw when off and therefore can go several months with no issues. My garden tractor has sat for 4+ months for 3 winters, outside, never seen a tender, and starts right up every time with no issues, still on the original battery.

no parasitic draw = no need to put on a tender or disconnect the battery. Just trying to save the OP some time and money

 

I put my Harley battery in lawn mower when old such small engines.

4 months seem like long time for bigger engine. I do think once a month,if he does ride it will work. Try it and find out.

Bring a jump pack if you have to be somewhere

 

Can you mount a solar battery charger somewhere? Amazon sells them pretty cheap.

 

Years ago I never used a battery tender on my bikes. But the current fobs signal the bike when near. My 2023 FatBoy114 flashes a red light every 30 seconds which can (over time) draw down the battery.

 

He doesn't have a fob or radio. A person with those could disconnect battery

 

I used a solar charger once, years ago, on a long extended camping trip. Worked well.
