DIY 100HP Lawn Tractor & Lawn Chopper Trike- Still Run?

Spring is finally here, which means it’s time to get my two favorite DIY custom projects ready for the season! In this video, I'm performing a full spring service, including oil changes, spark plug replacements, and a thorough wash using biodegradable products to keep the yard safe. It’s hard to believe, but it’s already been two years since I built the “Monster Murray” — that crazy 600cc lawn tractor powered by a 100HP Honda CBR 600 F3 engine. It's still pure madness on four wheels! Beside it stands the Racing Lawn Chopper Trike, which I finished almost a year ago. I built it around a unique Briggs & Stratton two-cylinder boxer engine, and I’m proud that it’s not just for show — it’s a fully functional racing mower that I still use to cut grass. If you want to see the full journey of how I created these machines from scratch, you can watch the complete step-by-step build videos below:
