Winding 300 feet of wet, heavy pressure washer hose back onto a reel by hand at the end of a long day is the worst part of the job. Your arms are tired, the hose fights you on every turn, and it takes five minutes of cranking that you would rather spend driving to the next job or going home. This 12V power rewind kit bolts onto your existing A-frame hose reel and adds motorized retraction so the reel winds itself while you guide the hose.
Press a switch, and the electric motor does the cranking. You just walk the hose back toward the trailer and guide it onto the reel with one hand. What used to take five sweaty minutes at the end of every stop now takes 60 seconds with almost no effort.
Compatibility
This 12V power rewind kit (part number 103166) is designed to fit GPA150, GPA300, and GPA450 series A-frame hose reels. If you have a General Pump or compatible A-frame reel in the 150, 300, or 450-foot capacity range, this kit will bolt on. The motor assembly mounts to the existing frame, and the drive connects to the drum axle.

Why Power Rewind Matters for Commercial Operations
Time is money in pressure washing. If you do four to six stops per day and spend five minutes hand-cranking your hose reel at each one, that is 20 to 30 minutes per day spent winding hose. Over a five-day work week, that is nearly two and a half hours. Over a season, it adds up to days of lost productivity on a task that generates zero revenue.
Power rewind also reduces physical wear on the operator. Repetitive cranking under load is hard on wrists, elbows, and shoulders. Over months and years of daily use, it contributes to fatigue and repetitive strain. The motor eliminates that mechanical stress entirely.
For crews with employees, power rewind means faster pack-up between jobs and less physical demand on workers. Faster transitions between jobs mean more jobs per day. Less physical strain means fewer complaints and lower risk of injury claims.
Installation Overview
The power rewind kit is designed for bolt-on installation with basic hand tools. No cutting, welding, or permanent modification to the reel frame is required. The general installation process involves mounting the motor assembly to the reel frame using the provided hardware, connecting the drive mechanism to the drum axle, running the 12V power wiring to your battery source, and mounting the control switch in a convenient location on your trailer or truck bed.
Most installations can be completed in under an hour. Detailed installation instructions are included with the kit. If you prefer professional installation, any mobile mechanic or trailer shop can handle it.
Power Source Considerations
The motor runs on 12V DC and draws power only when actively reeling. You have several power source options. The simplest is wiring directly to your truck battery with an inline fuse. For trailers, running a dedicated deep cycle battery gives you independent power without drawing from the tow vehicle. If your rig already has a 12V system for lights, pumps, or other accessories, you can tap into that existing circuit.
The motor draws modest current during operation. A healthy truck battery or a small deep cycle auxiliary battery will handle the load without any issues, even after a full day of use.

Frequently Asked Questions
Will this kit fit my existing reel?
This kit fits GPA150, GPA300, and GPA450 A-frame reels. If you have a different brand or model, call us with your reel specifications and we can confirm compatibility or suggest alternatives.
Can I still hand-crank the reel with the kit installed?
Yes. The power rewind kit adds motorized capability but does not remove the manual crank option. If your battery dies or the motor is unavailable, you can still wind the reel by hand.
How much battery power does it use?
The motor draws power only during active reeling, not continuously. A standard truck battery or a small deep cycle auxiliary battery provides more than enough capacity for a full day of reeling cycles.
Is this waterproof?
The motor and electrical connections are designed for outdoor use on pressure washing equipment, but they are not submersible. Normal splash and spray exposure from pressure washing operations will not damage the components. Avoid submerging the motor or leaving connections exposed to standing water.
