The Iron Horse is an exclusive J-Glover mobile plaster pump. Equipped with an Iron Horse plaster pump and a 1010 Powermix mixer, the Iron Horse can pump & mix plaster, finish, pebble, and fireproofing with ease. Unlike its competitors, the J-Glover Iron Horse is mounted on a full Spray Force wishbone torque-flex axle trailer with electric brakes for an incredibly smooth ride and the best longevity in the industry. This innovative suspension system makes for ease of transportation to and from the job sites day after day, while still maintaining its low-slung frame.. The Iron Horse is strong, reliable, durable, and a great value.
