938 Small Wheel Loader

The Cat® 938 Small Wheel Loader sets the standard for productivity, fuel efficiency, operator comfort and low operating costs. Experience the industry benchmark.

Enjoy All Day Comfort

  • Have a seat in the new Cat small wheel loader and enjoy automatic temperature control, class leading sound levels, enhanced all-around visibility and low-effort joystick controls that move with you on a fully adjustable seat suspension. A large spacious operator environment combined with Caterpillar hydraulic cylinder damping and smooth predictable controls make this the most comfortable seat on your jobsite.
  • An upgrade to multi-view camera and rear object detection gives you an extra eye on the jobsite while the new optional force feedback joystick steering keeps you feeling confident on those long shifts. The operator not present function helps to isolate the machine if you leave the environment; while seat belt notifications give you a gentle reminder to buckle up.

Efficiently Powerful

  • Experience the difference with an intelligent hydrostatic power train and industry leading fuel savings through a lower maximum engine speed working in combination with a new auto engine RPM mode. This provides efficiency as standard with a boost in power when you need it. Optimize traction and minimize wheel slip with a new Auto Wheel Torque system tuned to provide peak performance while maximizing tire life and keeping operating costs low. Track your production and accurately hit your load targets with Cat Payload.

Work Made Easy

  • Move more with the Caterpillar patented quick loading performance series buckets and optimized Z-bar linkage with enhanced forward visibility that combines the digging efficiency of a traditional Z-bar with tool carrier capabilities. The parallel lift and high tilt forces throughout the working range allow you to confidently handle loads with precise control.
  • Multi-function work has never been easier with dedicated pumps for each system and a flow sharing implement valve governed by an intelligent power management system. Simultaneously lift, steer, and drive without compromise. Upgrade to autolube to make service easy and get to work quicker. Light the way with auto roading lights that come on at night fall.

Customize Your Experience

  • Meet your application requirements and individual preferences with Caterpillar industry first Hystat™ Operator Modes featuring four unique power train settings. Select classic torque converter for smooth rollout, conventional hystat for aggressive engine braking, an ice mode that maximizes your control on slippery underfoot, and an all new single pedal mode for simplified use.
  • Fine tune machine performance with adjustments at your fingertips through programmable joysticks, soft touch buttons, and a new jog dial that works in combination with a standard touch screen display. Quickly recall attachment profiles that maintain key settings for versatility onthe jobsite and optimal efficiency.

Upgrades and Services

  • Enjoy a full range of upgrades and accessories to configure your small wheel loader for a broader range of applications.
  • Utilize readily available services and maintenance parts including a range of self-service options (SSO) and dealer installed kits.
