Steering system ensures that lawn tractors are easily maneuvered in the operator’s direction of choice. This calls for an effective steering system that is easy to operate, free from frictional resistant forces, free from faulty steering linkages. This article discusses steering problems common to Husqvarna lawn tractors. Most of the problems emanate from faulty mechanical elements that build up the steering system and dry joints that require lubrication. Additionally operation of equipment without proper manual guidelines from supplier may result in steering problems as discussed in detail below.

1. Steering Too Hard
The Husqvarna lawn tractor steering operation should generally be an easy operation. If steering becomes hard, this can be a good sign to show that there is need to make certain adjustments. The first thing to look out for is tyre pressure. Unequal tyre pressure in front wheels results in difficulties in Husqvarna lawn tractor steering. This is due to the resistance of the low pressure tyre at their frictional point of contact with the ground. Always ensure tyres are equally pressurized to recommended pressure levels to avoid hard steering due to low or unbalanced tyre pressure. Use of tyre pressure gauges is recommended to for this.
2. Steering Gear
The Husqvarna lawn tractor steering system relies on the linkage between the steering gear and the pinion. These meshing gears wear and tear due to use and in some instances they may dislodge when tractor hits a bumpy area or rock while in motion. Operation of the Husqvarna lawn tractors with faulty, damaged or broken steering gear results in problems with steering. Check the steering gears as per supplier procedure to realign dislodged gear and replace any broken or damaged gear to solve hard steering problem. To replace the broken gear, loosen the tightening bolt and fit a new one and tighten back. Steering should be normal.
3. Broken Bushings
The other common mechanical fault that develops with the Husqvarna lawn mower tractors steering system is the broken bushings. The purpose of the bushings is to hold the steering bolts gear in place. They are located just under the steering gear. If these units gets worn out or broken, this will result in vibrations in the gear shaft. If not solved this will eventually lead to gear failure and excessive wear and tear. It is recommended to check and replace all broken and damaged bushings as per supplier procedure.
4. Loss of Steering Power
The Husqvarna lawn mower tractor steering assembly consist of rods, washers and bearings. These are critical parts that forms the structure of the mechanism of steering in lawn mowers. If these units are not checked and gets worn out, loss of steering power is experienced. This may result in need for hard but very slow steering. Bushings, washers and rods need to be kept in good condition for efficient steering system. These also need lubrication to improve their life span and effectiveness.
5. Loose Husqvarna Lawn Mower Tractor Steering
In some instances, the steering will be loose and the wheel will not move. This is due to faulty tie rods in which case it needs replacement. With malfunctioning tie rods, the steering load is separated and hence the light or loose feeling on the steering. Steering will not move the wheel in such circumstances.
6. Steering Linkages And Cumber Angle
Another area to look for in case of hard steering on the Husqvarna models is the steering linkages. Steering linkages have different connections for different mowers designs and these are simply rods attached to the steering box. If these gets damaged, the mower steering is affected. All defective linkages requires immediate replacement to solve the problem. Incorrect cumber angle for wheels also results in hard steering problem. Cumber angle assist in turning or cornering by providing different wheel contacts with the ground. However incorrect angle results in excessive resistance to the steering effect of the steering. To solve such problem you have to engage Husqvarna experts to adjust the cumber angle as some require negative while some require positive cumber.
7. Steering Without Wheels Moving
This steering problem is common with the Husqvarna tractors and is commonly a result of disjoint in any steering linkage. This is largely due to mechanical failure from wear and tear of shafts, joints, washers and bolts and nuts. This then causes the steering to turn without any effect on wheels since the attachment is broken. Turning the steering to the left or right won’t have an effect on the wheels which will remain straight. One major cause of this experience is wear and tear of teeth on the Husqvarna lawn mower tractor steering sector or on the steering shaft. Check all gear teeth for condition and alignment to address this problem. The second area to look at is the transmission. Faulty transmission also results in steering problems. To solve this Husqvarna lawn mower steering tractor problem, engage a certified personnel or refer to the manuals as recommended by supplier. Additionally, the Husqvarna lawn tractors usually suffer from fasteners loosening. Operating the unit with loose fasteners results in weak steering power and ultimately steering power loss. Always check all fasteners, bolts and nuts for secure and tight connections. Replace all worn out fasteners and bolts to ensure efficient steering is maintained. This Husqvarna problem also emanates from hydraulic system failure. Depending on the make leaks on the hydraulic system results in pressure loss and ultimately in loss of steering. This Husqvarna lawn mower tractor steering problem requires proper checking of the hydraulic system, from hydraulic pipes for bursts, valves for failure and connections to the pump which supply the hydraulic fuel to the whole system.
To sum up this article on Husqvarna lawn tractor steering problems, it is important to check the whole steering linkage mechanism for loose connections, broken or excessively worn out joints, fasteners, washers, bolts, retainer caps, gears and shafts as these are critical for an easy and efficient steering system. This eliminates all mechanically related problems and the play on the steering induced by loose connections. Additionally, always check all joints for lubrication to avoid stiff steering. Use of recommended lubricant is required to address these problems. Always refer to supplier manuals for asset care.
