Bought the Troy Bilt. If it's built half as good as our tiller, it'll last a good long while.

Through research/years of use Ive found a couple tips to help prolong the life of them
*To avoid hand lock after hrs of use - use some velcro straps to keep the handle pressed down. Not safe if you go muzzle sweeping everyone with it or fall down, but it will save your hands over the years.
*Always prime the pump 100%. I use the velcro strap to keep the trigger pushed for about 5 minute prior to start up.
*Never let them idle. Never. After warm up either use them or turn them off. When you have them on full throttle and you aren't using the pump it is building heat and pressure that decreases the life of the pump severely (why on my new pump I got the overflow line to be about 100X longer than on the old pump - will hold more pressure & heat). This should really be tip #1 and the most important
*During break in if your pump has pressure adjustment - start it off slow and low. I ran mine for about a 1/2 day before I cranked it up and I'm still not running it at 100%.
