Why Choose Broken Tractor:

• ✅ Ninety Machines, One Sensor: The same sensor runs across the 8R tractor line, the G-series excavators, the L-series skidders and the K-series loaders.
• ✅ Two Engine Families Named: 4045 and 6090 applications are called out, so a repower or an OEM engine install is covered too.
• ✅ Light Part, Quick Ship: At under a pound this moves as a small parcel, not freight.
