I’ve spent the last 12 or so years quadding extensively, on rough terrain and with very heavy loads, while running treeplanting crews in BC. A lot of it only comes with experience, but some lessons I’ve learned, often the hard way, are:
- Weight should be balanced, but adjusted with steep slopes - ie. if you’re climbing something steep you need more weight at the front to maintain traction. Proper attention needs to be given to securing loads and also loose straps, etc. A heavy duty tie-down strap ending up in your axle can have pretty catastrophic results at high speed, for example.
- More weight = less stability, with a downward multiplier effect on stability after a certain weight. By this I mean an extra bit of weight on an already heavy machine often makes a much larger impact on stability than you might think.
- If you’re in gnarly terrain be sure you’re able to jump off if you need to. Getting off to walk machines over tricky sections always a great move.
- cheap/low quality and/tires are a massive liability.
- Avoid riding a machine into a truck whenever possible, I straight-up ban it where I work. 1/2-1 ton trucks can be loaded while standing off to the side easily and effectively with a little practise. Same goes with controlled unloading. High and very avoidable rate of accidents associated with loading/unloading in my experience.
- Complacency kills - accidents happen when you’re not paying attention, thinking about other things, or on easy terrain. Likely a contributing factor with OP’s buddy I’d expect.
- If you’re riding on a radio-controlled logging road either have a handheld and know how to use it or understand the need to be extremely careful. I’ve lost count of how many ATVs I’ve nearly flattened in my truck who have been on the wrong side of the road / out of control around corners / not paying attention/ drunk, etc etc. These encounters seem to happen a lot during hunting season.
- having gears offers a massive advantage in control and thus safety vs. high/low ranges or whatever other hokey stuff you can get. Honda all the way.
- high speed on roads etc much safer in 2wd. Front end tends to roll in 4wd at speed and on smooth(er) surfaces, especially when wheels are canted.
Prob forgetting some other important stuff but

Rubber side down everyone.
