Kubota Z125E Transmission Notes
Transmission type note
The key drivetrain answer for the Kubota Z125E is Hydrostatic. That matters first because transmission type changes how the tractor feels more than a small horsepower difference
Gears and range note
The captured gears/ranges detail for the Kubota Z125E is Infinite forward and reverse. Hydrostatic setups usually matter more for control feel than fixed gear count
Forward / reverse speed note
The useful speed numbers are 8.4 mph (13.5 km/h) forward and 4.5 mph (7.2 km/h) reverse. That gives a better driving comparison than transmission type alone
Buyer takeaway
If you are comparing tractors, judge the Kubota Z125E from Hydrostatic, Infinite forward and reverse, and 8.4 mph (13.5 km/h), not horsepower alone. Transmission setup decides how the tractor actually drives
The clean captured transmission type for the Kubota Z125E is Hydrostatic. Use that as the first answer, then check gears/ranges and travel speed.
Does the Kubota Z125E have fixed gears?
The listed transmission detail is Infinite forward and reverse. If the tractor is hydrostatic, treat this as range/speed information rather than a normal manual gear count.
How fast does the Kubota Z125E go?
The Kubota Z125E is listed at 8.4 mph (13.5 km/h) forward and 4.5 mph (7.2 km/h) reverse.

This row does not show a clean fluid capacity. Check the operator manual before doing a transmission or hydrostatic fluid change.
What should I check before buying a used Kubota Z125E?
Confirm the exact transmission type, test forward and reverse operation, check for fluid leaks, and verify any service history for the transmission or transaxle.
Official information note
Mistakes do happen. Tractor transmission specs can change by year, market, serial range, transaxle, trim and option package. Please check the operator manual, service manual, build sheet and official kubotausa.com website for official transmission information before servicing or buying parts.
