A highlighted cell wins its row on the rule named above the table: more power, lift, capacity or flow, or a lower price. A lift row is left unwon whenever the two makers measured in different places, or where either of them did not say — a figure quoted at the pivot pin and one quoted 500 mm ahead of it describe the same loader and differ by roughly a third, so ranking them against each other would invent a result. Prices are typical list and move with dealer packages.

From owner discussion and long-term write-ups

What owners of each one say

Bobcat CT4045

What they like

  • 2,716 lb of hitch capacity at 24 in behind the lift point is a 1,085 lb jump over the 2000 platform and opens up box blades and heavier rotary cutters
  • 16.5 gpm total flow - 9.6 implement plus 6.9 steering on the hydrostatic build - is half again what the 2000 platform offers
  • 1,795 lb of loader lift at max height finally makes pallet forks a sensible attachment
  • A turbocharged 111 cu in Daedong three-cylinder at 2,750 rpm rather than a bigger naturally aspirated block
  • An 8x8 synchro shuttle is available if you would rather change direction without a hydrostatic pedal
  • 18.5 mph top speed with a 71.2 in wheelbase makes it usable for moving between fields, not just around a yard
  • Optional mid-PTO at 2,119 rpm on the hydrostatic build

What they complain about

  • PTO output drops to 32.8 hp on the hydrostatic build from 41.6 hp on the manual - an 8.8 hp penalty, the largest transmission trade-off in the Bobcat line
  • Bobcat's own pages disagree on the fuel tank, 12.7 gal on the CT4045 page against 11.9 gal on its siblings
  • The CT4545 cab version costs $11,014 more
  • Emissions hardware is unstated on the model page, so any particulate filter and its regeneration cycle need confirming at the dealer
  • No warranty term is published

Bobcat CT4058

What they like

  • 57.7 hp is the most engine power Bobcat puts in an open-station tractor, and 45.1 PTO hp comes with it
  • 16.5 gpm of total flow is the platform's higher hydraulic figure, so loader work is quick
  • 2,716 lb of hitch capacity at 24 in behind the lift point handles the heaviest Category 1 implements
  • A cab version exists on the identical chassis as the CT4558 for $8,798 more

What they complain about

  • Hydrostatic is the only transmission offered, so buyers who want gears for long PTO sessions have to drop to the CT4050
  • At 57.7 hp the loader still lifts 1,795 lb at max height, the same as the 44.9 hp CT4045 - the whole platform shares one loader rating
  • 3,745 lb of operating weight is unchanged from the smaller 4000-platform models, which limits how much loader load the machine can counterbalance
  • 11.9 gal of fuel for nearly 58 hp is a short working window
  • Emissions hardware is not stated on the model page, so any particulate filter and its regeneration cycle must be confirmed at the dealer
  • No warranty term published
