Grime Task Force Gear Drive 5.5 GPM @ 3000 PSI — CRX420 (Cart, K7)

Built for contractors who need real commercial output without a bulky footprint, this gear drive pressure washer pairs a CRX420 engine with the Comet RW5535 pump to deliver a steady 5.5 GPM at 3000 PSI. The gear drive configuration reduces belt wear and the maintenance downtime that comes with it, which means more billable hours and fewer interruptions over the life of the machine.

This unit is mounted on a wheeled cart for easy repositioning around a job site, and runs pull start. Gear drive systems transfer engine power to the pump through a sealed gearbox rather than belts and pulleys, eliminating a common wear point and the periodic tensioning and belt replacement that belt-drive units require.

This configuration includes the K7 unloader, a flow-sensitive unloader valve that manages bypass pressure and helps protect the pump during trigger-off periods.

Every build includes a gun and wand assembly, spray tips, and a 50-foot section of high-pressure hose, so the machine arrives job-ready rather than needing accessories sourced separately. The engine carries a 3-year limited CRX warranty. Motor oil is 10w30 and pump oil is 30wt non-detergent.

This is equipment built for operators running a real cleaning business. Grime Task Force builds and stocks this configuration because it's what holds up in the field — commercial power and commercial reliability, day after day.

Please note: as a custom-built unit, this machine may require 1-2 weeks lead time before shipping.
