Columbia IS12 Stockchaser (24v) VS Pack Mule Stock Chaser SC-775 (24v)

FeaturePack MuleColumbiaWhy it matters

Tow Capacity

2,000 lbs

1,000 lbs.

Pack Mule pulls twice the weight, which means that you get more work done with each trip, increasing productivity and decreasing vehicle wear.

Cargo Capacity

1,000 lbs.

1,200 lbs.*

Pack Mule’s “cargo capacity” means just that. Columbia’s means “personnel, cargo, options, and accessories,” which would reduce the real cargo capacity substantially.

Deck Size Capacity

31.5" x 48” (1512 sq. in.) standard with six optional sizes

29.5" x 43” (1249 sq. in.)

Pack Mule gives you more than 20% more cargo deck, making loading easier and safer.


A/C Motor 9.2 hp (24 V), 13.2 hp (36 V), 17.7 hp (48 V)

Separately excited DC motor 5.2 hp (24 V), 15.5 hp (48 V)

The Pack Mule NXG’s more powerful A/C motor lets you get more work done, especially coupled with the controller that increases power when you need it and reduces it when you don’t.


245 amp/hour

232 amp/hour.

Higher amps per hour increase runtime and battery life. Pack Mule’s standard batter gives you more amp hours.


Precision Rack and Pinion Heavy Duty 1” steering pivot shaft. Front axle with tapered bearings and center support between front tires.

¾” steering pivot shaft and ¾” front axle with smaller bearings.

Ease and precision of steering not only affect driver performance, but also safety, especially in close areas. Additionally, the more robust steering greatly reduces downtime.

Throttle Control

Dual Hall Effect Throttle Control

Spring-connected Throttle Control

The Pack Mule NXG’s Dual Hall Effect throttle control substantially increases safety for both the operator and the load by significantly reducing the chance of loss of throttle control, resulting in a “runaway” vehicle.

Ergonomic Accelerator Pedal


Not Available (see note below)

Pack Mule’s pedal design makes it easy to drive. Columbia’s is set at twice the angle of Pack Mule’s, putting stress on the operator’s ankle, and the accelerator requires more than three times the effort.

Cargo Deck Material

Melomine Laminated Decking

Painted Plywood Decking

Melomine lamination provides longer life and prevents early failure due to warping or splitting.

Hour Meter


Not Available

Provides management and maintenance to accurately track vehicle usage so that preventative maintenance can be performed properly, decreasing machine failures.

Programmable high-frequency charger


Not Available

Pack Mule’s high-frequency charger uses temperature compensation and automatic cell equalization to optimize run time and extends battery life.

Operator Friendly Ergonomic Matting


Not Available

The ergonomic matting increases operator comfort and reduces fatigue, increasing productivity and safety.

Fully-enclosed Operator Foot Area


Not Available

The fully enclosed operator foot area increases operator safety and comfort as well as protecting the internal workings of the vehicle.

Adjustable Backrest


Not Available

The adjustable backrest allows the operator to set it to the most comfortable position, increasing operator comfort, productivity, and safety.

Steps on Back Rest


Not Available

Let’s the operator move quickly and easily to hard-to-reach places, saving time and reducing operator fatigue.

Hitch Plate

Multi-position hitch plate

Single position hitch plate. No upgrade.

Multi-position hitch plate allows hitch height to be adjusted to meet the specific application.


Three-year Warranty

Two-year Warranty

Pack Mule’s confidence in its quality allowed it to introduce the industry’s first (and only) three-year warranty.

*This is “load capacity,” not cargo capacity. It includes “personnel, cargo, options, and accessories.”


How we compare the Pack Mule to the competition.

We go to great lengths to make sure that our comparisons between Pack Mule vehicles and others are as fair and accurate as possible. It doesn’t serve anyone’s interests for those depending on the comparisons to be disappointed. Basically, here’s how we do them:

  1. We purchase competitor vehicles from time to time through authorized channels, usually a dealer, specifying standard equipment and asking for quotes on appropriate upgrades.
  2. The competitor vehicle is tested alongside the Pack Mule.
  3. Wherever possible, we use the specifications on the machine we purchased. When we need additional specs, we use the ones published on the competitor’s web site, in the quote we received from their authorized dealer or published in their user manuals.
  4. We frequently check to see if anything has changed. If it has, we immediately change the comparison, as we do when the competitor provides us documentation of a change.
  5. We offer to back our comparisons up with on-site demos. If you’re currently using another manufacturer’s electric industrial vehicle, we’ll provide a Pack Mule for you to do your own comparison.
