Repair service for Tuff Torq transmissions

In the normal course of events we will advise that the unit is taken to your regular garden machinery dealer for repair. Not only does this avoid the need to ship a heavy item around the country but also means that the repairer can test the transmission in the host machine. If we carry out a repair without the host machine we can only bench test it. We will of course supply your dealer with all the parts and technical backup needed to complete the job. The exception to this preference for local repair is the model K55 transmission. This unit was used in many machines including Countax, Westwood, Husqvarna and Stiga but has been out of production for several years. Subject to certain conditions we will take these transmissions back for repair in our workshop. If you have an issue with one of these units please phone our Service Department 0208 908 4744, 09:00 – 17:00 Monday – Friday. 


This unit has been used in newer Countax and Westwood tractors. Many of these units are starting to show signs of wear, particularly if they have not had regular oil changes – typically loosing power when hot, particularly in reverse. Due to the cost of repair parts and labour it is usually recommended that a new box be fitted. We can supply the latest K46 CM that is a direct replacement for the 46E or supply repair kits for rebuilding worn boxes. Another option is to rebuild K46E units to a higher specification by the addition of an internal charge pump effectively turning them into the heavier duty K57. For more details talk to our Service Department – 0208 908 4744.

Quick trouble-shooting.

A few things to check before concluding that there is an internal problem with the transmission.

  • Is there sufficient oil in the transmission?
  • Is the by-pass valve fully closed? – often referred to as the dump, freewheel or tow valve.
  • Is the brake binding?
  • Is the transmission being properly driven? – is the drive belt in good condition and being correctly tensioned when “in drive”?
  • Is the transmission pulley actually turning the input shaft? – worn splines in the pulley boss can result in a pulley that rotates but doesn’t drive the box. Usually audible as a harsh metallic noise.
  • Are the “instructions” from the control lever or pedal actually being relayed to the box? Check for out of adjustment machine linkages or even a fractured or missing roll pin where the control arm fits to the control shaft where it enters the box.
