Detailed comparison insights:

Engine and Power:

The Kubota F3990 offers slightly higher horsepower (39 HP) compared to John Deere’s 37–38 HP Yanmar diesel.

Both provide robust diesel power suited for commercial mowing and snow removal. Kubota’s turbocharged V1505T engine provides ample power for heavier workloads.

Transmission and Maneuverability:

The John Deere 1585 uses an automatic AWD system with hydrostatic transmission and simple pedal controls, offering dependable traction especially on tough terrain and slippery conditions.

Kubota’s F3990 features rear-wheel steering (making it steer like a zero-turn mower) which is excellent for tight areas and enhanced maneuverability in complex landscapes.

Emissions and Reliability:

The John Deere 1585 has been noted for its reliable Tier 4 diesel engine without significant regeneration issues.

Kubota’s F3990 had earlier reputations for diesel particulate filter (DPF) regeneration problems, which caused some dealers to caution against it, although more recent reports suggest these issues have been largely addressed.

Attachments and Versatility:

Both machines offer a wide array of attachments, including snow blowers, blades, rotary brooms, and cab options with HVAC.

The John Deere 1585’s versatility and proven field service support make it a strong commercial favorite.

Operator Comfort:

Both offer cabs with heating and air conditioning, ensuring operator comfort year-round.

User Opinions:

Some users favor the Kubota F3990 for its power and maneuverability, particularly if they can accept dealing with past emission system complexities, while others trust the Deere 1585 for its simpler, proven reliability and ease of maintenance.

Recommendation:

If you prioritize reliable, proven performance with minimal emissions system complexities, the John Deere 1585 is a strong choice ideal for commercial mowing and snow removal.

If you want maximum power and zero-turn style maneuverability and are comfortable with potential emission system maintenance, the Kubota F3990 offers excellent capabilities with a slightly higher power rating and innovative design.

Ultimately, the decision depends on your operational priorities—ease of maintenance and trusted reliability (John Deere 1585) vs. maximum power and maneuverability (Kubota F3990), balanced against your comfort level with potential emissions system intricacies on the Kubota.
