Hi AC, thank you for your recent inquiry with The Home Depot. The Honda GX390 Pressure washer does not come with a skid mount, it only comes with the wheel kit as shown. We appreciate your business and look forward to serving you in the future. Thank you for shopping Home Depot.

Customer Reviews

Water Blaster 4,200 psi 4.0 GPM Belt Drive Gas Pressure Washer Powered by Honda is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from Excellent Pressure Washer I have always purchased the high-end consumer 2800 to 3000 PSI Washers for about $500 and did not see the need for a larger unit, but I have a lot of concrete and a large fence that I wash every year. The standard units blew up about every 3 years so I just threw it out and bought another one, still cheaper than paying someone else. I finally decided to purchase this pressure washer (a real one) and I am very happy I did, jobs take 1/2 the time and the cleanup is a much better job, well worth the price. But your arms will be sore from using this machine because it is so powerful, but a lot of fun to use. I think I sold 3 more of them while I was using it; all my neighbors were coming over and asking where I purchased it.
