Kubota GR2110 transmission leaking oil out of overflow tube

[msn56]

Kubota GR2110 (serial 16105). Hydraulic oil is expelled from the transmission breather only after the machine warms up. The breather hose was kinked and when I went to check the oil it shot out under pressure I unkinked the hose and now it literally empties the transmission after several hours out of the Breather hose There is no case pressure with breather open. Tractor drives, steers, and lifts normally until oil level drops, then the HST begins to whine. New hydraulic filter and correct oil. Has anyone seen this before? Replace two of the hoses DOnt see any air leaks

Is the cooling fan intact and not damaged?

in addition to checking the above I would also check to be sure there isn’t a build up of grass and debris by the fan and the transaxle which could cause heat buildup.
