I was going to put my rig up for sale until I read these reviews. I dont understand how all these other rigs wouldnt drill. I purchased the 13 hp and I drilled a well within the first month. I had to do two things. One I had to chase the threads on the drill stem with a 150.00 tap to clean out all the weld splatter. Two I had to purchase a better mud pump hose coupler. The mud pump is more than sufficient. To ease transportation I welded a tow hitch on my drill frame and I brazed carbide all around my 7inch reamer so I could drill and ream in a single pass. I cut down through rock to 50ft and I have more that enough water. Try doing that with any other rig. There is a little wobble frome the water swivel but goodness gracious what do you want for under 10 grand. I can drill down to 200 ft in a couple of days and that is a 10,000$ well here on the nothern California coast. I guess I wll keep mine and start drilling wells for a living. Anyone with a little sense can iron out any wrinkle this rig might have. If you want email me custom_xmods .  I understand why hydra jett wouldnt respond to everyone about everylittle thing but that is propably hurting there sales and reputation...Get a a clue hydrajett, good product but unhappy customers?
