The creator calls out a key distinction other videos may miss: the Scuttle Shift has no spin-on transmission filter, only an inline strainer. Practical tips on drain order, O-ring prep, and bleeding air make this most useful to RK37 owners doing their own first service.
The creator appears to be an independent mechanic or small shop operator servicing a customer's tractor, giving the video a practical, real-world repair perspective rather than a dealership or manufacturer angle.
No. The Scuttle Shift model has no spin-on oil filter for the transmission. The only filter is an inline strainer located near a hose under the tractor.
Remove the crossmember by undoing bolts on both sides, drop the support, then unbolt and pull the strainer straight out after draining the transmission fluid first.
According to the manual used in the video, the RK37 takes about 3.2 quarts of 10W40 engine oil.
The transmission fluid is shared with the hydraulics, so cycling all gears and running the loader and rear hydraulics helps bleed air from the system.
