Weasler 77 Series PTO Shaft Parts
PTO drive shaft parts are crucial for farm machinery, and understanding them can help you operate your equipment more efficiently. PTO shafts are critical parts of your tractor and are commonly overlooked during routine maintenance checks.
In addition to the PTO drive shaft, you should also look for any other PTO shaft parts that can cause damage to the tractor. A broken or damaged shaft can cause the tractor to perform poorly. Fortunately, most of these parts are easy to replace and are not expensive. WLY PTO drive shafts are made of a durable alloy that’s designed to withstand the stresses placed on the machine. However, if you do need to replace the drive shaft, you should first consider the model of your tractor. You can also find extra parts for your tractor’s PTO drive shafts at WLY.

How to Shorten a PTO Shaft？
1. Remove the safety shield.
2. Shorten the inner and outer tubes according to the required length. Shorten the inside and outside tubes once at a time by cutting the same length.
3. Deburr edges of the drive tubes with a file and remove all filings from the tubes.
4. Shorten the inner and outer plastic tubes according to the required length. Shorten the inner and outer plastic tubes once at a time by cutting the same length.
5. Grease the internal drive tubes and reassemble them with a safety shield
Check the minimum and maximum length of the drive shaft installed on the machine. In working conditions, the drive tubes should overlap 2/3 length and the plastic tubes should never be separated.
Agricultural Gearboxes and PTO Shafts
Agricultural equipment includes a variety of PTO shafts. Each one is connected by yokes at each end and rotates between 540 and 1,000 rpm. A safety shield is commonly installed on both ends of a PTO shaft to protect the operator. These protective shields are also found in tractors and agricultural implements, and they ensure maximum efficiency. Added safety is also provided by the use of internal yokes.
The agricultural PTO gearbox is designed to change the output speed of a PTO drive shaft. It can be used as a decreasing or increasing ratio gearbox. With the decrease ratio gearbox, it reduces the PTO shaft's speed from 1000 rpm to 540 rpm, allowing you to use equipment designed for 540 rpm. On the other hand, an increasing ratio gearbox increases the speed of the PTO shaft from 540 rpm to 1000 rpm.
Together, the PTO shaft and agricultural PTO gearbox form a critical link between the tractor and the implement, allowing farmers to efficiently and effectively manage their land and crops.
