However, it's not especially efficient, it's definitely obsolete, and it's prone to various failures. I had more trouble with the reverse relay than anything else on my E15. The final straw for me was the snowstorm where I was plowing the driveway with the hood open and the panel unscrewed so I could push on the reverse relay to make the tractor back up. Adding a modern solid-state controller markedly improves the tractor's manners and reliability. The downsides of controller conversion are 1. You gotta pick (relatively) cheap or (relatively) easy. You can't have both. 2. Unless you're a well trained up-to-date electronic engineer, the controller becomes an unfixable black box to be sent out for service or replaced if/when it fails. Fortunately, that normally doesn't happen very often.
