John Deere groups excavators into three classes by operating weight: compact excavators from 3,800 to 13,500 lbs, mid-size excavators from 16,500 to 90,000 lbs, and large excavators from 103,500 to 188,750 lbs. Operating weight, not horsepower, is the spec that defines the class and determines what you can haul.
Most contractors shop by weight for a practical reason, since weight sets your trailer and truck requirements, your ground pressure, and whether the machine fits the site at all. Here, we’re breaking down the sizing of John Deere’s compact excavator lineup.

John Deere Compact Excavator Sizes
Compact excavators (also called mini excavators) run 3,790 to 13,620 lbs and handle utility trenching, landscaping, residential sitework, and excel in tight spaces like fenced-in areas.
| Model | Operating Weight | Net Horsepower | Max Dig Depth |
| 17P | 3,790 lbs | 14.5 HP | 7’2″ |
| 26P | 6,110 lbs | 20 HP | 8’6″ |
| 30P | 7,220 lbs | 23 HP | 9’2″ |
| 35P | 8,135 lbs | 23.3 HP | 10’0″ |
| 50P | 10,847 lbs | 35.9 HP | 11’7″ |
| 60P | 13,620 lbs | 53 HP | 12’4″ |
The 35 P-Tier is one of the best sellers in this group, because at 8,135 lbs, it tows behind a three-quarter-ton truck on a suitable trailer and still reaches 10 feet.
The step from the 35 to the 50 P-Tier is the one to think hardest about. You gain 2,700 lbs, 12 more horsepower, and 19 inches of reach, but you also move into heavier trailer territory.
How To Choose the Right Excavator Size
When sizing for your crew, it’s easier to work backward from your constraints rather than forward from your wish list, and these three questions will usually settle it.
- How deep do you actually dig? Buying 25 feet of reach to dig 9-foot trenches is money sitting idle.
- How tight is the site? Access width and swing clearance rule out machines that otherwise fit the job.
- What is the ground like? Soft or sloped ground favors more weight and wider tracks.
Match the machine to your most common job rather than your biggest one, and rent for the outlier.
What Does Operating Weight Really Tell You?
Operating weight tells you a few important things at once: what it takes to haul the machine, how much force it can apply without tipping, and how much ground pressure you should plan for. Heavier machines dig harder in dense material, but that same weight is a liability on finished surfaces and soft ground. That’s why you shouldn’t consider only digging depth when purchasing your excavator—where a 17P and 60P can get the job done, a 17P is likely a safer choice.

Frequently Asked Questions
What size is considered a mini excavator?
John Deere classifies compact excavators at 3,800 to 13,500 lbs. In common use, “mini excavator” means roughly anything under 10 tons, which covers the 17 P-Tier through the 60 P-Tier.
How much does a John Deere 35P excavator weigh?
The 35 P-Tier has an operating weight of 8,135 lbs. and a maximum dig depth of 10 feet.
What is the difference between an excavator and a trackhoe?
Nothing. “Trackhoe” is regional slang for a tracked excavator. “Digger” is used the same way in some areas.
How deep can a mini excavator dig?
Among the compact models above, 7 feet 2 inches on the 17 P-Tier to 12 feet 4 inches on the 60 P-Tier.
