I was thinking about making a custom implement for my tractor - a water tank wit attached sprinklers (with simple valve) and small 12V pump with a short hose. It would allow to address fire spots that are numerous and small but too far to run to them with buckets of water - usually in 100 F heat + fire heat plus smoke.
They make premade pump & water tank assemblies for ATVs & trucks. I think they are available for tractors too. It would be fairly easy to install one for ATVs on a tractor's 3 point hitch. Here's another thread that has some pix of them
installed on ATVs.
We used tractor disks for fire prevention. We made firebreaks with them. Before the fire was started. I suppose a lot depends on type of tractor & the terrain but I generally prefer a 4 wheel drive ATV over a tractor for fighting a fire that is already burning. They are very effective because they're small, fast, maneuverable in tight conditions, & can put a lot of water exactly where needed.
There are some excellent suggestions already mentioned above. The basic idea is to remove excess fuel, especially around houses & other structures. One thing specific to NM & other places with arroyos is, well, arroyos. Once a fire starts on the lower end of those it rips upwards extremely fast. Pay special attention to arroyos! Once a fire starts there it's usually too late to do much about it. I've seen too many very expensive houses along the scenic top of arroyos & canyons completely destroyed in seconds, yes seconds, simply because there was too much fuel below.
One lesser known but useful tool that often works better than water or vehicles is a powerful leaf blower. One of those can blow a long line of burning leaves, etc back into itself & eliminate the threat very quickly.
